本文进一步研究了环氧乙烷-环氧丙烷嵌段共聚物(L61和F68)、聚丙二醇(PPG)分别与十六醇(CA)、硬脂酸(SA)所形成的二元混合膜.根据对π-a实验结果的分析,表明PPG-CA、PPG-SA、F68-SA和L61-SA的混合单分子膜是不相混溶的,而L61-CA和F68-CA的混合单分子膜则是混溶的.
In this paper, the binary mixed films of ethylene oxide-propylene oxide block copolymer (L61 and F68) and polypropylene glycol (PPG) with cetyl alcohol (CA) and stearic acid (SA) were further studied. Based on the analysis of the results of π-a experiments, the mixed monolayers of PPG-CA, PPG-SA, F68-SA and L61-SA were immiscible whereas the mixed monolayers of L61-CA and F68-CA The membrane is miscible.
