Synthesis of Copper-polystyrene nanocomposite particles in water in supercritical carbon dioxide (sc-CO2) medium and its antimicrobial activities

I.R. Kamrupi and S.K. Dolui
Copper encapsulated polystyrene nanocomposite particles were prepared through ex-situ dispersion of Cu nanoparticles into monomer droplets and subsequent polymerization using water-in-sc-CO2 at 70oC. First, colloidal dispersion of copper nanoparticles were synthesized by chemical reduction of...

Synthesis of silver-polystyrene nanocomposite particles in water in supercritical carbon dioxide (sc-CO2) medium and its antimicrobial activities

I.R. Kamrupi, P. Phukon, S.K. Dolui and B.K. Konwer
A novel method based on ex situ dispersion of silver nanoparticles within the monomers and subsequent emulsion polymerization using water-in-sc-CO2 medium is introduced in this paper. Silver nanoparticles were synthesized by chemical reduction of silver nitrate using sodium borohydrate as a...

Synthesis of stable dispersion of Copper nanoparticles in a water-in-supercritical carbon dioxide (sc-CO2) using Polydimethyl siloxane (PDMS) as the stabilizer

I.R. Kamrupi and S.K. dolui
Reported herein is the synthesis of stable dispersion copper nanoparticles by chemical reduction of Copper Chloride (CuCl2) in a water-in supercritical carbon dioxide (sc-CO2) medium using sodiumborohydrate (NaBH4) as reducing agent, polydimethylsiloxane (PDMS) as the stabilizer and Sodium...
