Abstract

To prepare very stable acrylic type emulsion having a visible ray absorption property, in-situ preparation technique of $Cu_xS$ nanoparticle was adopted. Firstly, the acylic emulsions of methyl methacrylate(MMA), butyl acrylate(BA), and acrylonitrile(AN) were synthesized by pre-emulsion polymerization at $60^{\circ}C$ in the presence of anionic surfactant. Secondly, $Cu_xS$ nanocomposited emulsions were directly prepared in the prepolymerized acrylic emulsion with $CuSO_4$ at $50^{\circ}C$. The presnce of $Cu_xS$ nanoparticle in emulsion was confirmed by SEM and EDS. The final $Cu_xS$ nanocomposited emulsion showed an olive-green colour and good emulsion stability up to 1 month. In addition the PET films coated with our $Cu_xS$ nanocomposited emulsion absorbed effectively the visible ray.
