Chen, Hong published the artcileInterpenetrating polymer network hydrogels using natural based dyes initiating systems: Antibacterial activity and 3D/4D performance, Recommanded Product: Ethyl 4-dimethylaminobenzoate, the publication is European Polymer Journal (2022), 111042, database is CAplus.
In the past few decades, interpenetrating polymer network (IPN) hydrogels have attracted huge attention due to their special cell-like structures, interpenetrating interface, and two-phase continuity, which has special synergistic effects on their performance and function. In this work, the best candidates were selected from the firstly synthesized 11 dyes based on 1-aryl-3-(2,4,5-trimethoxyphenyl)prop-2-en-1-one or 3-aryl-1-(3,4,5-trimethoxyphenyl)prop, and then combined with an amine (i.e., 1,4-(dimethylamino) Et benzoate, EDB) and an iodonium salts (bis(4-tert-butylphenyl)iodonium hexafluorophosphate, Iod) as a three-component visible light photoinitiating systems (PIS) to induce both free-radical photopolymerization (FRP) of poly(ethylene glycol) diacrylate (PEG-DA) and cationic photopolymerization (CP) of 3,4-epoxycyclohexylmethyl-3′,4′-epoxycyclohexanecarboxylate (EPOX) and in situ reduction of silver cations into silver nanoparticles to prepare interpenetrating network polymers (IPN) with antibacterial activity for Gram-pos. bacteria (e.g. Staphylococcus aureus) and Gram-neg. bacteria (e.g. Pseudomonas aeruginosa). More interestingly, stable 3D patterns were successfully produced through direct laser write (DLW) technique, and they exhibited reversible swelling properties and shape memory effects caused by swelling and dehydration processes, thus enabling 4D printing.
