两亲聚合物功能单体对聚集及界面行为影响

以环氧乙烷与环氧丙烷共聚物（m=环氧乙烷数，n=环氧丙烷数，其中：m和n值分别对应m=16和n=18，m=16和n=6，m=16和n=2），苯基-4-戊烯（1-苯基，1，1-二苯基和1，1，1-三苯基）和1，3-双（二甲基丁基溴化铵）-2-丙烯酰氧基丙烷（碳链个数分别为8，12和16）作为功能单体，室内合成了系列两亲聚合物样品。通过稳态荧光实验、动态光散射、扫描电镜、透射电子显微镜等仪器系统考察m/n值，苯基和碳链个数对两亲聚合物聚集行为和聚集体形貌的调控作用及其对油水界面性质影响。研究发现，两亲聚合物溶液在固体表面吸附后形成空间网络状结构；在溶液体相中，随着m/n值，苯基和碳数增加，聚集体尺寸增加，聚集体形貌更密集；对于油水界面性质和乳化原油能力，随着m/n值，苯基和碳数增加，油水界面张力和接触角变小，乳化油滴尺寸越小。

Influence of Amphiphilic Polymer Functional Monomer on Aggregation and Interface Behavior

The functional monomers, including ethylene oxide and propylene oxide copolymer (m=the number of ethylene oxide, n=the number of propylene oxide, m and n values correspond to m=16 and n=18, m=16 and n=6, m=16 and n=2), phenyl-4-pentene (1-phenyl, 1, 1-diphenyland 1, 1, 1-triphenyl), and 1, 3-bis (dimethyl methylbutyl bromide) 2-acryloyloxy propane (the number of carbon chain is 8, 12 and 16, respectively.) were synthesized as a series of amphiphilic polymer samples. Through steady-state fluorescence experiments, dynamic light scattering, electron microscopy scanning, and transmission electron microscopy, we made a study on m/n values, and on how phenyl and carbon atoms influence the aggregate behavior of amphiphilic polymers and interfacial properties of water and oil. It was found that a spatial network structure formed after adsorption of amphiphilic polymer solutions by a solid surface. In the bulk solution phase, with an increase in the m/n value, phenyl group, carbon number, and the aggregate size, the morphology was denser. In terms of oil-water interfacial properties and emulsion for crude oil capacity, with an increase in m/n values, phenyl and carbon atoms, the lesser the oil-water interfacial tension and the smaller the contact angle, the smaller was the emulsion droplet size.
