在纳米A l粒子表面的苯乙烯原位聚合反应中,反应体系的组成(单体用量、引发剂用量、稳定剂用量及A l粒子用量)会对A l/PS微胶囊的形态、粒径大小及分布产生一定的影响。当纳米A l粒子用量小于5%,苯乙烯用量为20%,引发剂及稳定剂用量分别为单体用量的0.5%和1.5%时,制备出的A l/PS微胶囊呈球形,表面光滑无明显缺陷,颗粒之间分散性很好,粒径为1.345μm,分散系数为13.1%。 In the in situ polymerization of styrene on the surface of nano-Al particles, the composition of the reaction system (monomer amount, initiator amount, stabilizer dosage and A l particle amount) Size and distribution have a certain impact. When the amount of nano-A l particles is less than 5%, the amount of styrene 20%, the amount of initiator and stabilizer were 0.5% and 1.5% of the monomer content, prepared A l / PS microcapsules spherical, smooth surface No obvious defects, the dispersion between the particles is very good, the particle size of 1.345μm, dispersion coefficient of 13.1%.
