Nylon-polystyrene microcapsules sensitive to an outside stimulus such as an external electric field were prepared by the combination of interfacial polymerization and solvent evaporation techniques. A ferroelectric liquid crystal monomer possessing both mesogenic group and chirality was much effective as a functional component which responds to an external electrical field. The liquid crystal extremely has a sensitive response to the outside stimulus, because it has spontaneous polarization. The microcapsules immobilized the liquid crystal could control the permeability of oxprenolol, which is used as an encapsulated core material, compared to that of the microcapsule without the liquid crystal under the external intermittent electrical field. In addition, we characterized the electro-responsive controlled release mechanism by the polarized light transmittance measurement.

采用界面聚合和溶剂挥发相结合的方法制备了对外界刺激如电场敏感的尼龙-聚苯乙烯微胶囊。同时具有介晶基元和手性的铁电液晶单体作为响应外电场的功能组分是非常有效的。由于液晶具有自发极化特性，因此它对外界的刺激有极其灵敏的响应。与不含液晶的微胶囊相比，固定液晶的微胶囊可以控制用作包封芯材的氧烯洛尔在外部间歇电场下的渗透性。此外，我们还通过偏振光透射率的测量来表征电响应控制释放机制。
