The article was titled 《Polyacrylamide crosslinked by bis-vinylimidazolium bromide for high elastic and stable hydrogels》. The information in the text is summarized as follows:
A series of ionic compounds 1,n-dialkyl-3,3′-bis-l-vinylimidazolium bromide (CnVIM) are prepared and employed to crosslink acrylamide for polyacrylamide (PAAM) hydrogel preparation via in situ solution polymerization The swelling behavior, mech. properties and thermal stability of the prepared CnVIM crosslinked PAAM hydrogels are investigated. CnVIM effectively crosslink the PAAM networks to form porous structures in the hydrogel, which could stably absorb water as much as 75.9 fold in weight without structural degradation The prepared hydrogels could endure compressive stress up to 1.95 MPa and compressive deformation more than 90%. Meanwhile, the CnVIM crosslinked networks show superior thermal stability, and could retain the structural integrity under 150°C for more than 240 h. The swelling degradation resistance, mech. strength and thermal stability of CnVIM crosslinked hydrogels are much better than those of a conventional N,N’-methylenebisacrylamide crosslinked PAAM hydrogel. Using bis-vinylimidazolium bromides as crosslinkers provides an optional strategy for constructing thermally and mech. robust hydrogel networks. In the part of experimental materials, we found many familiar compounds, such as 1,6-Dibromohexane(cas: 629-03-8Recommanded Product: 629-03-8)
1,6-Dibromohexane(cas: 629-03-8) is generally used to introduce C6 spacer in the molecular architecture. Some of the examples are: synthesis of solvent processable and conductive polyfluorene ionomers for alkaline fuel cell applications; synthesis of cross-linkable regioregular poly(3-(5-hexenyl)thiophene) (P3HNT) for stabilizing the film morphology in polymer photovoltaic cells.Recommanded Product: 629-03-8
