영문 초록

To prepare very stable acrylic type emulsion having a visible ray absorption property, in-situ preparation technique of CuxS 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℃ in the presence of anionic surfactant. Secondly, CuxS nanocomposited emulsions were directly prepared in the prepolymerized acrylic emulsion with CuSO4 at 50℃. The presnce of CuxS nanoparticle in emulsion was confirmed by SEM and EDS. The final Cux S nanocomposited emulsion showed an olive-green colour and good emulsion stability up to 1 month. In addition the PET films coated with our CuxS nanocomposited emulsion absorbed effectively the visible ray.
