Effect of Particle Size on the Synthesization of Latex Nanoparticles

Abstract

The differential microemulsion polymerization method was used to prepare the latex nanoparticles at different amount of monomer. The monomer mixture consists different amount of butyl methacrylate (BMA) that was varied from 5.7 g to 9.7 g. Thin film of latex nanoparticles was prepared using the spin coating method and has been dried at 100°C for 5 minutes. The particle sizes of latex nanoparticles were characterized using Zetasizer nanoseries and the structural properties of the samples was studied using Atomic Force Microscopy (AFM). As the BMA amount increased, the particle sizes of latex nanoparticles has found to decrease from 69.66 nm to 31.16 nm and the roughness has detected to reduce from 3.78 nm to 2.63 nm. We have found that the BMA content in the polymerization has sensitively effect the particle sizes and the structural properties of the latex nanoparticles.
