通过可逆加成-断链链转移(RAFT)溶液聚合,以三硫代碳酸酯为RAFT试剂,偶氮二异丁腈(AIBN)为引发剂,1,4-二氧六环为溶剂,制备甲基丙烯酸(2,2,2-三氟)乙酯(TFEMA)和苯乙烯(St)共聚物.详细研究了不同引发剂的用量、RAFT试剂与引发剂摩尔比以及聚合温度等实验条件对聚合反应过程的影响.通过GPC、FTIR测试共聚物的分子量、分子量分布和分子结构,并用静态接触角仪和AFM分别表征聚合物膜的接触角、表面能及膜的表面形貌. The product was prepared by RAFT solution polymerization using trithiocarbonate as RAFT reagent, azobisisobutyronitrile (AIBN) as initiator and 1,4-dioxane as solvent (2,2,2-trifluoroethyl) methacrylate (TFEMA) and styrene (St) copolymer.The effects of different conditions such as the amount of different initiators, the mole ratio of RAFT agent to initiator and the polymerization temperature The molecular weight, molecular weight distribution and molecular structure of the copolymer were measured by FTIR and GPC. The contact angle, surface energy and surface morphology of the polymer films were characterized by static contact angle meter and AFM respectively.
