Fabrication of nonspherical polymer particles by using microporous film

In natural world, Isotropic sphere of polymeric nano- and micro-particles are originated from the shape of hydrophobic monomer nano- or micro-droplet in water, since surface tension was acted on the surface of the droplet. In other words, preparation of nonspherical nano- or micro-particles is challenging and attractive field. In this presentation, self-organized preparation method of new nonspherical particles will be reported. The preparation method of the nonspherical particles bases on the fabrication of the composite structure of microporous film and nanoparticles introduced into the micropores by self-organization process. Structures of nonspherical particles were originated in those of the assembly of particle in micropores of the composites.
