Xu, Kangming; Chen, Guoqing; Zhao, Mingjie; He, Weiyi; Hu, Qiaoman; Pu, Yong published an article in 2022, the title of the article was Transparent, self-recoverable, highly tough, puncture and tear resistant polyurethane supramolecular elastomer with fast self-healing capacity via “hard-soft” hard domain design.Application of 517-23-7 And the article contains the following content:

The integration of superior mech. properties and fast healing efficiency for self-healing polyurethane supramol. elastomers is challenging due to the confliction between high chain mobility for healing and high chain rigidity for mech. properties. Herein, a strategy to design a “hard-soft” hard domain by the cooperation of quadruple hydrogen bonds (HBs) in the mainchain as restriction units and single HBs in the side chain as diffusion units is reported. The resulting transparent supramol. elastomer exhibited fast self-recoverability, good puncture resistance and superior mech. properties with a tensile strength of 20.5 MPa, an extensibility of 2043.7%, a toughness of 146.1 MJ m-3 and a tear resistance of 13.8 kJ m-2. Moreover, the fast self-healing capacity (healing efficiency > 82% within 3 h under moderate condition) was realized due to the soft effects of weak HBs in the side chain on the strong HBs in the mainchain. Taking advantage of the merits of the supramol. elastomer, a flexible sensor was simply fabricated, which showed good self-repairable and stable sensing properties. Thus, the elastomer has great potential in the field of flexible electronics and wearable devices. The experimental process involved the reaction of 3-Acetyldihydrofuran-2(3H)-one(cas: 517-23-7).Application of 517-23-7

And the article contained the following:

A well-defined quadruple hydrogen bonding strategy involving dimerization of 2-ureido-4[1H]-pyrimidone (UPy) units is innovatively designed to prepare polyureas with high overall mech. properties. Three polyureas containing different amounts of UPy units were synthesized by replacing a portion of isophorone diisocyanate (IPDI) with a UPy-derived diisocyanate. The formation of quadruple hydrogen bonds in hard segments via UPy dimers was confirmed by NMR and fourier transform IR spectroscopy. The mech. properties of the polyureas were evaluated by uniaxial tensile testing. Compared to the polyurea without UPy units, remarkable improvements in Young’s modulus, tensile strength, and toughness were simultaneously achieved when UPy units were incorporated. The mechanism behind the strong strengthening effect rooted in the stronger intermol. forces among hard segments brought by the quadruple hydrogen bonds, which were stronger than the inherent bidentate and monodentate hydrogen bonds among urea groups, and the slower soft segmental dynamics revealed by both increased Tg and relaxation time of the soft segments. The mechanism behind the strong toughening effect was ascribed to more effective energy dissipation brought by the quadruple hydrogen bonds that served as stronger sacrificial bonds upon deformation. This work may offer new insight into the design of polyurea elastomers with comprehensively improved mech. properties. The experimental process involved the reaction of 3-Acetyldihydrofuran-2(3H)-one(cas: 517-23-7).Product Details of 517-23-7

And the article contained the following:

Self-healable polyurethane elastomers have potential applications in many fields, however, their use is limited by single self-healing mechanism, intricate preparation process, and long curing time. Herein, a UV-irradiation/thermo dual-induced self-healing polyurethane elastomer is prepared by UV-curing two kinds of acrylates, where one includes a quadruple hydrogen bond (PU-UPy-HEA) and the other contains a disulfide bond (SS-MA). UV-curing kinetics indicate that the conversion of acrylates is significantly improved by tuning the irradiation intensity, photoinitiator dosage, and SS-MA content. A maximum conversion of 80% is achieved within 10 s under 200 mW cm-2 in the case of the 1.5 weight% photoinitiator. The tensile strength of UV-cured polyurethane elastomer is notably improved by SS-MA, whereas its elongation at break decreases. Tensile shear tests demonstrates that the bisected samples can be re-bonded when they are repaired at 100°C for 15 min, or under 200 mW cm-2 irradiation for 1 h. After that, ∼90% of shear strength is recovered and the strength is only slightly reduced after two healing cycles. Self-healing mainly relies on thermally reversible hydrogen bonding interactions and UV-induced disulfide metathesis. This UV-cured self-healable polyurethane elastomer can be used in smart coatings as well as in other fields. The experimental process involved the reaction of 3-Acetyldihydrofuran-2(3H)-one(cas: 517-23-7).SDS of cas: 517-23-7

And the article contained the following:

Hydrophobic elastomers are required for use in industry and daily life because of their versatile properties. Developing a hydrophobic elastomer with self-healing abilities and excellent mech. performance has been very challenging because of the mutually exclusive nature of these properties. Herein, supramol. polydimethylsiloxane (PDMS) elastomers with excellent self-healing and mech. properties were designed through the synergetic combination of multistrength H-bonds and disulfide bonds. The hierarchical H-bonds formed with urethane, urea, and 2-ureido-4[1H]-pyrimidinone (UPy) moieties in the backbone of the supramol. polymer endow the resultant polymers with effective reversible crosslinking, whereas during stretching, the dynamic dissociation and reassociation of H-bonds enable polymers with high extensibility and enhanced toughness and recoverability. In addition, disulfide bond exchange under heat enables polymer network rearrangement, thus imbuing the supramol. elastomer with excellent self-healing ability. Based on the extraordinary properties of hydrophobic supramol. PDMS elastomers, some smart materials can be prepared, such as oil/water separation foams and hydrophobic hot-melt adhesives. Therefore, this concept of synergetic dynamic bonds will point out a direction for the development of sustainable, green, and functional materials of the next generation.

And the article contained the following:

Achieving good transparency, high strength and superior extensibility simultaneously in autonomic self-healing elastomers remains challenging and fascinating. Herein, a complementary design strategy of combining densely distributed multiple hydrogen bonds and loosely packed spacer units in supramol. elastomer was reported to address the inherent contradiction of robust strength and room temperature self-healing. The chem. structure can be tuned to achieve a good compromise between the mech. properties and self-healing efficiency. The representative elastomers can achieve robust strength (6.81 MPa), high extensibility (2520%) and superior toughness with the dissipated energy up to 63.7 MJ/m3. Moreover, this elastomer is capable of recovering mech. fractures and routine scratches with the self-healing efficiency up to 90%, which are comparable to that of room-temperature self-healable counterparts. Spacer units with steric hindrance effect can facilitate segmental motions and dynamic changes of H-bonds. Meanwhile, the randomly distributed multiple H bonds crosslinking such spacers contribute to the good mech. performance and intriguing self-healing. In contrast to previous reports, this strategy provides an uncomplicated and cost-effective route to prepare robust elastomers that can self-heal at room temperature without any need of external assistance.

And the article contained the following:

This research aimed to optimize the extracting condition of banana peel (BP) and to investigate the effect of organic banana peel extract (BPE) on the immunity of giant freshwater prawn (Macrobrachium rosenbergii). The result demonstrated that the optimum extracting condition of organic BPE was 50% volume/volume of methanol at 100°C for 10 min. Under this condition, the maximum total phenolic content and extraction yield of 10.44 mg of gallic acid equivalent (GAE) per g of dry matter (mg GAE/g DM) and 33% w/v were obtained resp. The organic BPE could inhibit an aquatic pathogen Aeromonas hydrophila at the min. inhibitory concentration of 625μg/ disk. The main phytochems. in organic BPE showed two major biol. functions, which are antioxidant and antipathogenic activities. Subsequently, the effects of organic BPE on the immunity of M. rosenbergii were investigated. The results demonstrated that the organic BPE could increase immunity and phagocytic activity and decrease the susceptibility of M. rosenbergii. Moreover, the organic BPE could also increase total as well as differential hematocyte count, decrease the coagulation time and increase the total protein in serum of M. rosenbergii. The phagocytic activity of prawn was enhanced to 82.00% by using an organic BPE at 6μg/g. At the same time, the cumulative mortality was declined to lower 20% after 6 days of organic BPE injection. In conclusion, organic BPE can be a potential immunostimulant in giant freshwater prawn culture. The utilization of BP in aquaculture can further add the value of BP and reduce organic pollutants.
