제목 2-DIMENSIONAL STRAIN SENSING CAPABILITY OF POLYMER-IMPREGNATED EXFOLIATED GRAPHITE NANOPLATELET-MULTIWALLED CARBON NANOTUBE HYBRID SHEETS
초록 Extensive experimental study has been conducted on polycarbonate (PC) impregnated exfoliated graphite nanoplatelet (xGnP) / multiwalled carbon nanotube (MWCNT) hybrid sheets. The hybrid sheets were fabricated through surfactant-aided carbon nanomaterial dispersion followed by vacuum-induced filtration. The inherently porous sheets were impregnated with polycarbonate by infiltrating a polycarbonate-chloroform solution through the sheets. Electromechanical properties of PC-impregnated sheets had proven their strain sensing capability and unique direction dependent piezoresistive characteristics under cyclic flexural loading. The study demonstrated successful hybridization of two carbon nanomaterials with varying morphologies, which can be used as performs for easy-to-handle, high-carbon-content, multifunctional composite strain sensor with tailorable sensitivity and mechanical property.
