Effects of Preparation and Self-Assembly of Poly(Styrene-Acrylic Acid) (P(St-AA)) Microspheres upon Constructed Photonic Crystals with Structural Color on Wood Surfaces

Colloidal microspheres could be used as raw materials to construct the photonic crystal modification layers on wood surfaces, and would produce gorgeous structural color effect. The diameter, monodispersity self-assembly of colloidal directly affect well-structure order crystals. Therefore, poly(styrene-acrylic acid) (P(St-AA)) shell-core were prepared by emulsion polymerization. effects reaction time, amount initiator emulsifier temperature particle size dispersity during polymerization analyzed single-factor experiments. P(St-AA) self-assembled surfaces formed crystals with through thermally-assisted gravity deposition. coating per unit surface area ambient optical properties investigated. It was found that synthesized increased increase decrease emulsifier; however, effect time less regular. best obtained using 0.408 ?L/mm2 at a 50 °C. composed both ordered disordered layers.
