摘　　要：不对称的乳胶粒子属于Janus粒子的范畴,而Janus粒子是近年发展起来的一种具有独特性质的粒子。Janus粒子表面物理或化学性质不同,其在催化、光学、材料、生物传感、生物医药及电子学等领域具有广阔的应用前景。本研究用乳液聚合法合成不对称P(St-co-AA)/PS乳胶粒子,并从热力学和动力学角度探索了反应温度、引发剂用量、乳化剂量和不同溶胀比等对不对称乳胶粒子形态和尺寸的影响。Asymmetric latex particles belong to the category of Janus particles which are developed in recent years with unique properties.Janus particles have different surface physical or chemical properties,so they have broad application prospects in the fields of catalysis,optics,materials,biosensors,biomedicine and electronics,etc.Asymmetric P(St-co-AA)/PS latex particles are synthesized by emulsion polymerization.The effects of reaction temperature,initiator dosage,emulsification dosage and different swelling ratio on the morphology and size of asymmetric latex particles are investigated as viewed from thermodynamics and kinetics.
