Polymeric nanocomposites have been received significant attention in chemistry, biology, and material science because they are worthy to apply to various industrial fields, our daily life. The polymeric nanocomposite can be a potential material that has the merit to use for liquid crystal, bio-imaging, and drug-delivery. Plasmonic nanoparticles can create both energetic charge carriers, i.e., hot electrons and thermal energy through light-to-matter interaction. Those energetic particles can be acts as an initiation source to proceed polymerization at the surface of Au NPs. In this study, we pursued photo-polymerization of acrylic acid on Au NPs under visible light with control of irradiation intensity, excitation wavelength, and reaction temperatures. The resultant was characterized by UV-Vis spectrophotometer, TEM, XRD, and so on. Consequently, we observed that poly(acrylic acid) was wrapped on the surface of Au NPs with a varying thickness depending on the experimental conditions. |
