【摘要】 基于一种新型聚电解质水凝胶及其与黏土杂化水凝胶的合成,考察了所得凝胶的溶胀性能。与单一聚电解质凝胶相比,含黏土的杂化型凝胶有增强的溶胀能力和pH敏感性;其溶胀机理遵循Fickian扩散模式。更多还原

【Abstract】 A new polyelectrolyte hydrogel and its hybrid hydrogel with the Laponite clay were prepared, and their swelling properties were investigated. In comparison with pure polyelectrolyte hydrogel, the hybrid hydrogel containing the clay has enhanced swelling ability and increased pH-sensitivity. The swelling mechanism of these hydrogels was found to follow the Fickian diffusion mode.更多还原
