The demand of nonspherical particles at photonic crystal has leaded to an increasing research interest in nonspherical particles since 2001.Nonspherical particles have became a recent hot field of material due to their low symmetries

novel properties and wide potential applications.The synthesized approaches include seeded polymerization

self assembly

particle clusterization

microfluidics and mechanical stretching.This paper outlines the developing course of seeded polymerization

presents relating formed mechanism of nonspherical particles

reviews the main morphologies and structures of nonspherical polymer particles.The potential applications of these materials and future trends in the fields are also been described.
