本文研究了不同温度时KCl对浸有P204聚酰胺胶囊的渗透速度。从Arrkenius图上得到了KCl的渗透系数随温度改变有一转变点(约5℃),从而证明了这一转变温度是膜中双亲分子形成复合双层结构的晶型转变温度(Tc)—相转变温度。所以,验证了P204在聚酰胺胶囊膜中是以复合双层结构形式存在的。 In this paper, the penetration rate of KCl impregnated with P204 polyamide capsule at different temperatures was studied. From the Arrkenius diagram, it is found that the transformation coefficient of KCl has a transition point (about 5 ° C) with temperature, which proves that the transition temperature is the crystal transition temperature (Tc) -phase transition of amphiphilic double layer structure temperature. Therefore, it is verified that P204 exists in the form of composite bilayer in the polyamide capsule membrane.
