Properties of Triboelectric Nanofiller/PDMS Composite Films
Triboelectric nanogenerators provide a new direction for energy harvesting and sensor monitoring.The high output performance of frictional layer materials is crucial.This study investigated the influences of different raw material ratios on the tensile properties of polydimethylsiloxane(PDMS),as well as the effects of various inorganic fillers(silica,titanium dioxide,graphite,halloysite nanotubes)and titanium dioxide filler concentrations on the electrical and tensile properties of PDMS films.The results show that the curing agent mass fraction has a certain impact on the tensile properties of PDMS,exhibiting elastic deformation within 100%strain.The four types of inorganic fillers enhance the electrical output performance of PDMS in different degrees.Among them,the titanium dioxide/PDMS composite film exhibits the best electrical output performance.When the mass of titanium dioxide accounts for the PDMS mass percentage of 8%and the working frequency of the electrical performance measurement platform is 2 Hz,the highest open-circuit voltage of titanium dioxide/PDMS composite film reaches 160 V,which is 8.4 times higher than that of pure PDMS film.This titanium dioxide/PDMS composite film also shows optimal tensile properties.This study provides references for improving the properties of PDMS films with nanofillers.
