Ordered Colloidal Crystals Fabrication and Studies on the Properties of Poly (Styrene–Butyl Acrylate–Acrylic Acid) and Polystyrene Latexes
Monodisperse poly(styrene–butyl acrylate–acrylic acid) (P(St–BA–AA)) and polystyrene (PS) colloidal suspensions were prepared using emulsion polymerization technique with a view to study their variation in properties. The P(St–BA–AA) latex had a slightly lower glass transition temperature (Tg) (106 °C) compared to the PS microspheres (104 °C). TEM analysis revealed a core-shell morphology in the P(St–BA–AA) latex particles, as compared to the PS particles. The synthesized latex suspensions were used to fabricate mono- and binary-sized colloidal crystals via the evaporation-induced self-assembly approach. SEM/AFM analyses showed spherically shaped particles that readily assemble into a closely-packed three dimensional highly periodic pattern with hexagonal symmetry. Also, the smaller sized P(St–BA–AA) particles (197.3 nm) in the binary crystals arranged themselves in a well-ordered manner around the larger sized PS particles (404.9 nm). The results showed that the modification made on the functional group of PS by polymerizing with butyl acrylate and acrylic acid produced P(St–BA–AA) latex with more improved properties compared to the as-synthesized PS.
