A Review of P(St-MMA-AA) Synthesis via Emulsion Polymerization, 3D P(St-MMA-AA) Photonic Crystal Fabrication, and Photonic Application

The possible applications of photonic crystalsPhotonic crystals (PhCs) in photonics and optics have increased their relevance in recent times. The propensity of PhCs to interact with light in their structure has led to a variety of thrilling and extraordinary features, which have shown possible usage in the generation of full-colour displaying films, coatings, switches, filters, photonic papers, responsive optical devices, etc. Polymeric materials have played an important part in the fabrication of PhCsPhotonic crystals owing to exceptional properties such as high strength, resistance to corrosion, resilience, colour, transparency, processing, and low cost. Among the utilized polymers, poly(styrene-methylmethacrylate-acrylic acid) (P(St-MMA-AA)Poly(Styrene-MethylMethacrylate-Acrylic Acid) (P(St-MMA-AA) has been utilized by several studies to generate photonic crystalsPhotonic crystals with unique structural coloursStructural colours for photonic application due to the exceptional features introduced by its functional groups. This paper provided a brief explanation of the synthesis P(St-MMA-AA) of colloidal particles via emulsion polymerization, 3D photonic crystal fabrication, and photonic application.
