Abstract
A one-pot synthetic procedure was successfully used to synthesize monodispersed poly (styrene-butyl
acrylate-acrylic acid) (P (St-BA-AA)) colloidal spheres via emulsion polymerization. A glass transition temperature (Tg)
of 108 oC was obtained by DSC analysis. Core-shell morphology was revealed by TEM micrograph. Evaporative induced
self-assembly process was used to fabricate photonic crystals from the as-synthesized P (St-BA-AA) latexes. Microscopic
analyses of the fabricated photonic crystal films revealed the assembling of colloidal particles which rearranged into a
fascinating compact three-dimensional periodic hexagonal structure with manifold layer arrangement. The photonic
crystal films displayed mesmerizing monochromatic yellow, blue and green colours which were obtained by controlling
the size of the microspheres. The prospect of deliberately obtaining photonic crystals with monochromatic colours would
be very useful in the generation of photonic crystals for sensing application.
