Abstract

Abstract Polyurethanes have been designed and fabricated into membranes with unique separation properties. Moreover, polyurethane microcapsules also have been reported actively as controlled release materials for their excellent blood compatibility, tensile strength and permeability. In this study, polyurethane microcapsules were synthesized by interfacial polymerization in an aqueous poly(ethylene glycol) dispersion of toluene diisocyanate in perfume oil using poly(vinyl alcohol) as the stabilizing agent. The effect of a few important process conditions on the average particle size and distributions, morphologies, and thermal properties to design microcapsules for the sustained release system was investigated.
