The Numerical and Experimental Investigation of Piezoresistive Performance of Carbon Nanotube/Carbon Black/Polyvinylidene Fluoride Composite

The composites with multiple types of nano-carbon fillers have better electrical conductivity and piezoresistive properties as compared a single type fillers. As previously reported, the various aspect ratios, such carbon nanotube (CNT) black (CB), synergistic enhanced effects on performance composite sensors. However, most works that been reported are experimental investigations. efficient usable numerical simulation investigation needs to be further developed. In this study, based an integrated 3D statistical resistor network model, model was created calculate behavior CNT/CB/ Polyvinylidene Fluoride (PVDF) composite. This also takes into account tunneling effect between nearby nano-fillers. It is found from results sensitivity cells can influenced by fraction CNT CB. case content 0.073 wt.%, best force-electrical achieved when CB loading up 0.2 wt.%. To verify validity previous compared. confirm model. valuable utilized design strain sensor for nano-composite increased sensitivity.
