Synthesis of Polydispersed P(St-MMA-AA) Microspheres and Fabrication of Colloidal Crystals with Non-Compact Morphology

Great attention has been given to the synthesis of monodispersed and uniform colloidal polymer particles with controllable particle sizes. However, investigations on preparation, characterization fabrication polydisperse polymeric are very few. Polydisperse polymers also needed meet new demands modern markets due ease their synthesis. This study, therefore, synthesized polydispersed poly(styrene-methyl-methacrylate acrylic-acid) (P(St-MMA-AA)) via emulsion polymerization synthetic approach under unstable reaction conditions. The P(St-MMA-AA) microparticles were characterized using Fourier transform infrared spectroscopy (FTIR), dynamic light scattering (DLS), a thermo-gravimetric analyzer (TGA) scanning electron microscope (SEM). DLS results revealed highly an average diameter 803.4 nm. SEM, TEM (transmission microscopy) AFM (atomic force analyses showed that spherical polydispersed. unequal diameters non-compact nature fabricated crystals may have affected its possible uses in some specific applications such as decorative coatings, biomedical sensing applications. other materials can be incorporated into prepared microspheres improve properties applications.
