Fabrication of NanoGs/PPy/Polymethacrylate (PMMA)-Epoxy Conductive Films

摘要

Nanographite sheets (NanoGs)/polypyrrole (PPy)/polymethacrylate (PMMA)-epoxy conductive films have been successfully prepared. NanoGs were prepared by treating the expanded graphite with sonication in aqueous alcohol solution. Then nanocomposite films were fabricated by in-situ polymerization of pyrrole in the presence of NanoGs by using epoxy resin and PMMA blends as copolymer matrix. From the thermogravimetric analysis, the introduction of epoxy resin and a few PMMA blends exhibited a beneficial effect on the thermal stability of pure PPy. According to the four-point probe test, the conductivity of the final nanocomposite films was about 1.5 × 10−3 s/cm.View full textDownload full textKeywordsConductive films, Epoxy resin, NanoGs, PMMARelated var addthis_config = { ui_cobrand: "Taylor & Francis Online", services_compact: "citeulike,netvibes,twitter,technorati,delicious,linkedin,facebook,stumbleupon,digg,google,more", pubid: "ra-4dff56cd6bb1830b" }; Add to shortlist Link Permalink http://dx.doi.org/10.1080/10426914.2012.663147
