Abstract
The present invention relates to a method of preparing antibacterial nanocomposite in supercritical fluids. In particular, the invention involves incorporation of antibacterial nanofillers into polymer matrix through either mixing a vinyl functional monomer, a polymerization initiator ,contacting the mixture with supercritical carbon dioxide and heating at a temperature and time to induce the insitu polymerization or infusing an antibacterial nanofiller into a polymer matrix swollen in supercritical carbon dioxide . The method further involves depressurizing the contents under ambient conditions to isolate the antibacterial nanocomposites. Fig:l
