Hoshino, Ken-ichi; Nakajima, Tasuku; Matsuda, Takahiro; Sakai, Takamasa; Gong, Jian Ping published an article in 2018, the title of the article was Network elasticity of a model hydrogel as a function of swelling ratio: from shrinking to extreme swelling states.HPLC of Formula: 79642-50-5 And the article contains the following content:
In this work, we intended to investigate the relationship between the swelling ratio Q and Young’s modulus E of hydrogels from their contracted state to extreme swelling state and elucidate the underlining mol. mechanism. For this purpose, we used tetra-poly(ethylene glycol) (tetra-PEG) gel, whose network parameters are well known, as the polymer backbone, and we succeeded in tuning the swelling of the gel by a factor of 1500 times while maintaining the topol. structure of the network unchanged, using an approach combining a mol. stent method and a PEG dehydration method. A master curve of Q-E, independent of the method of obtaining Q, was obtained. Using the worm-like chain model, the exptl. determined master curve can be well reproduced. We also observed that the uniaxial stress-strain curve of the hydrogel can be well predicted by the worm-like chain model using the structure parameters determined from the fitting of the Q-E exptl. curve. The experimental process involved the reaction of Bis(2,5-dioxopyrrolidin-1-yl) glutarate(cas: 79642-50-5).HPLC of Formula: 79642-50-5
