Abstract :
This paper presents the fabrication of nano-porous polymer microcapsules using self-assembly of the block copolymers in the microchannel. The spherical microcapsule with the diameter of about 25 mum was successfully fabricated with the thickness distribution of 0.5-1.5 mum and nano pores. Its potential as an encapsulant use was demonstrated by comparing the release performance under the various microenvironments.
