Abstract
A correlation is established between the mesh size of a swollen cross-linked network and its equilibrium polymer volume fraction, for hydrogels isothermally swollen up to semidilute, dilute, or concentrated conditions. The exponent of this correlation decreases as the water concentration of the hydrogel decreases. Experimental results with hydrogels of poly(vinyl alcohol) and poly(2-hydroxy ethyl methacrylate) are used to verify the new scaling laws.
摘要
对于在等温条件下溶胀至半稀溶液、稀溶液或浓溶液状态的水凝胶，建立了其溶胀交联网络的网孔尺寸与其平衡聚合物体积分数之间的相关性。随着水凝胶中水浓度的降低，这种相关性的指数减小。使用聚乙烯醇和聚甲基丙烯酸 2-羟乙酯水凝胶的实验结果来验证新的标度律。
