Abstract :
Samples of novel nanocomposites of multiwalled carbon nanotube and poly (dimethylsiloxane), i.e., CNT-PDMS, at different filler concentrations are prepared. The mechanical/electrical and piezoresistance properties of these nanomaterials are studied in detail. The gauge factor (GF) of this nanocomposite, dependent on the content of CNT, ranges from 1.38 to 12.4. Since the CNT-PDMS can be easily used as a novel piezoresistor using low-cost MEMS technology, this nanomaterial has decent potential in nanosensors and PDMS-based microfluidic systems.
