Atomic Force Microscopy Characterization of Latex Nanoparticles Synthesized by Slow Drying Process of Nano-Emulsion Polymerization

Abstract

The nano-emulsion polymerization method was used to synthesize the latex nanoparticles. Two set of samples are prepared by fast drying and slow drying process. For each process they have a two different amount of monomer. The monomer consists of butyl methacrylate (BMA), butyl acrylate (BA), and methacrylic acid (MAA). The average particle size of latex by fast drying process is 31.94nm for low amount of monomer and 19.59nm for high amount of monomer. By slow drying process the average particle size of latex nanoparticles for low and high amount of monomer are 26nm and 8.62nm respectively. All the samples that were prepared are characterized by Atomic Force Microscopy (AFM). We have found that the butyl methacrylate (BMA) content in between 6g and 10g has sensitively effect to the synthesization of nano-polymer for the both method of fast drying process and slow drying process of nano-emulsion polymerization method.
