Effect of Cross-Linking Degree on Hydrogels using Surfactant Detergent as Template

摘要: To avoid the formation of layer-pore structure and flocculation caused by excessive introduction nonionic surfactant detergent polyoxyethylene 20 cetyl ether (Brij58) into poly N-isopropylacrylamide/inorganic nanoclay hectorite hydrogels network (PLH hydrogels), inorganic content, severed as physical cross-linker, was increased from 1wt% to 3wt%. The morphology, temperature- responsibility, capacity water absorption swelling kinetics resulting PHL were investigated SEM, DSC Gravimetric method, respectively. It found that PLH would keep well honeycomb-like pore with increasing content. Furthermore, exhibited good temperature sensitivity regardless cross-linker
