Abstract

This article describes the generation and characterization of colloidal crystals from particles of gum arabic (GA) and sodium dodecylbenzene sulfate (SDBS) emulsified poly(styrene methylmethacrylate-acrylic acid) (P(St-MMA-AA) latex. The colloidal latex was synthesized using GA and SDBS as the emulsifying agents and then used to generate colloidal crystal films via the vertical deposition technique. Dynamic light scattering analysis placed the average particle diameter, polydispersity and Zeta potential at about 122 nm, 0.014 and –36.20 mV for the as-synthesized GA emulsified terpolymer latex and 213 nm, 0.006, –35.60 mV for the SDBS emulsified terpolymer latex, respectively. Thermo-gravimetric analysis and differential scanning calorimetry showed comparable thermal stability for both prepared terpolymer samples. Microscopic analysis showed that the latex particles possess a core-shell morphology which readily assembles into a well ordered hexagonal arrangement of spherical particles with manifold layers. This study, therefore, shows comparable properties of terpolymer prepared using gum arabic as emulsifier with terpolymer synthesized using SDBS which is a conventional emulsifier.
