電場応答型マイクロカプセルの調製とその評価

概要

A nylon-polystyrene microcapsule sensitive to an outside stimulus such as an electric field was prepared by the combination of both interfacial polymerization and solvent evaporation techniques. A ferroelectric liquid crystal monomer containing carboxyl-p-benzoyloxybenzoate (the mesogenic core) and carboxyl-(s)-(-)-2-methylbutylester (the terminal group) was much effective as a functional component which responds to an electric field. The monomer extremely has a sensitive response to an outside stimulus such as an electrical field, because it has spontaneous polarization. The microcapsule immobilized the ferroelectric 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.
