| Abstract Scope |
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 and their properties examined. The P(St-BA-AA) latex had a slightly lower glass transition temperature (Tg) (106 oC) compared to the PS microspheres (104 oC). 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 assembled 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 improved properties compared to the as-synthesized PS and this may find use in optical applications. |
