Research Abstract

Microcapsules have been drawing much attention as intelligent materials. In particular, functionalized polymeric microcapsules are eagerly studied in the chemical and industrial fields. Microcapsule membranes are semipermeable and therefore have disadvantage in that they cannot trap small substances in the inner phase. To overcome, we prepared a novel functionalized polystyrene microcapsule whose porous membrane was corked with ferroelectric liquid crystalline segments.
In this study, we prepared microcapsule with the ferroelectric liquid crystal, and investigated in detail the permeability control of oxprenolol, a model encapsulated drug, through the membrane of an electro-receptive nylon-polystyrene microcapsule^<1'2>). In addition, the permeability mechanism, with or without the electrical field, was quantitatively characterized by means of polarized light transmittance measurement. We specifically investigated the changes in behavior of the liquid crystalline segment of the microcapsule membrane under an electrical field.
