合成了多种不同配比的N 异丙基丙烯酰胺 (NIPAM )与丙烯酰胺 (AM )的共聚物 .研究了共聚物溶液在温度变化过程中发生的线团 胶粒转变 ,及荧光探针分子扩散进入疏水胶粒的动力学过程 .研究了扩散过程的动力学 ,计算了探针对不同配比共聚物扩散过程的活化能 ,并进行了比较和讨论 .研究表明 ,AM在共聚物中的比例越大 ,相变形成的胶粒结构就越疏松 .此外值得注意的是 :在采用混入法引入探针用以测定该转变点时必须注意存在的探针分子的扩散问题 . A series of copolymers of NIPAM and acrylamide (AM) with different ratios were synthesized.The changes of colloidal particles during the temperature change of the copolymer solution were investigated, and the fluorescence probe molecules The kinetics of diffusion into the hydrophobic colloidal particles was studied.The kinetics of the diffusion process was studied.The activation energy of the probe for the diffusion process of different copolymer was calculated and compared and discussed.The results show that AM in the copolymer The larger the ratio, the more porous the colloidal structure formed by the phase change It is also noteworthy that the diffusion of probe molecules must be observed when introducing the probe using the incorporation method to determine the transition point.
