聚苯乙烯乳胶球三维有序体的制备及其显微形貌表征

摘要

A three-dimensional(3D) ordered structure was achieved by self-organization of monodisperse polystyrene latex about (250 nm) in diameter after being ambient dried.The stacked morphology was investigated by scanning electron microscopy(SEM) observation.It is shown that the face-centered cubic(FCC) phase dominantly exists.This finding presents a potential template for preparing an inverse FCC structure as a photonic crystal of full band gap if the index contrast is higher than 2.8.
