ELECTROMECHANICAL PROPERTIES OF POLYCARBONATE-IMPREGNATED GRAPHENE NANOSHEET-CARBON NANOTUBE HYBRID COMPOSITE SHEETS

摘要

This paper presents an experimental study on fabrication and characterization of polycarbonateimpregnatednano graphene plates (NGP)-multiwalled carbon nanotube (MWCNT) hybridcomposite sheets. The NGP-MWCNT hybrid sheets were fabricated through surfactant-aidedcarbon nanomaterial dispersion followed by vacuum-induced filtration. The hybrid sheets wereproduced at various NGP:MWCNT ratios. The inherently porous sheets were impregnated withpolycarbonate by infiltrating a polycarbonate-chloroform solution through the sheets. Themechanical and electrical properties of the hybrid sheet preforms as well as the polymerimpregnatedsheets were characterized. The morphologies of hybrid sheets and compositeswere analyzed through SEM to assess the interaction between NGP and MWCNT network andthe effect of porous nanostructure on polymer infiltration.
