Abstract

Utilizing emulsion polymerization, a microcapsule breaker with a polystyrene-polyacrylamide core-shell structure was synthesized. Ammonium persulfate served as the breaker, polystyrene as the shell, and polyacrylamide as the drug-carrying agent. The results demonstrated that the synthesized microencapsulated gel-breaker exhibited a uniform spherical shape, superior water dispersion, and enhanced thermal stability. Conductivity tests indicated that the core-shell structure of the microcapsules effectively regulated the release of ammonium persulfate as a gel-breaking agent, resulting in delayed polymer gel-breaking.

具有核壳结构的 P（St-AM）微胶囊破胶剂的制备与性能评估

利用乳液聚合法合成了一种具有聚苯乙烯-聚丙烯酰胺核壳结构的微胶囊破壁剂。过硫酸铵作为破壁剂，聚苯乙烯作为外壳，聚丙烯酰胺作为载药剂。结果表明，合成的微胶囊凝胶破壁剂具有均匀的球形、优异的水分散性和更强的热稳定性。电导率测试表明，微胶囊的核壳结构有效地调节了作为破胶剂的过硫酸铵的释放，从而延迟了聚合物的破胶。
