温度敏感性水凝胶的合成及其相行为研究

通过辐射聚合以及引发剂引发聚合方法合成了一系列温度敏感性水凝胶，并比较了两法的利弊，运用弹性模量法研究了凝胶的网络结构及其影响因素，并讨论了其对凝胶样品的温度溶胀曲线的影响，测定了水凝胶在空气中的浊点曲线，认为：凝胶本身的浊点是反映其凝胶－凝胶相平衡的热力学行为。

Studies on the Syntheses and the Phase-Behaviours of the Temperature-Sensitive Hydrogels

Both the radiation-induced polymerization and initiator-induced initiation poly-merization methods were used to prepare a series of temperature-sensitive hydrogels of acry-lamide and its derivatives.The method of elastic modulus was adopted to study the networkstructure and affectable factors on it.The temperature-swelling curves and cloud-pointcurves of the hydrogels were measured and discussed.It is shown that the cloud-point of gelsis a thermodynamic behaviour reflected the gel-gel phase equilibrium.
