| Abstract: | By employing multi-walled carbon nanotubes(MWNT) and SiO2 as fillers and silicone as matrix,(MWNT-SiO2)/RTV composites were prepared by three roll mills mixing method and the piezoresistive and dielectric properties of composites were investigated.The results showed that the use of KH570 modified silica could improve the dispersion of fillers in matrix and the interface binding between fillers and RTV.After modified SiO2,the pressure sensitivity of(MWNT-SiO2)/RTV composite become stronger.When the outside p... |
