چکیده
Abstract As a representative piezoelectric polymer, poly (vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP) has been widely used in sensors transducers and actuators. In this paper, gold nanoparticles (AuNPs) are prepared doped into the PVDF-HFP solution to enhance property of electrospun nanowires. The results indicate that proper amounts AuNPs within nanowires can improve phase PVDF-HFP. Then, nanogenerator was using PVDF-HFP/Au verify increase performance. Experimental show compared with without doping, output voltage is increased by about two times, while current doubled for nanogenerator. Furthermore, systematic molecular dynamics (MD) simulations conducted elucidate physical mechanism enhanced β-phase formation Our adsorption electrostatic interaction between PVDF chains promote electroactive formation, also significantly tension poling effect during electrospinning process, which origin

Poly(vinylidene fluoride-hexafluoropropylene) (PVDF-HFP) porous membranes are fabricated via thermally induced phase separation (TIPS) with mixed diluent (dibutyl phthalate (DBP)/dioctyl phthalate (DOP)). The effects of mixed diluent are discussed in detail in term of morphology, mean pore size, selective wettability, etc. The results show that the membrane structure changes from spherulitic to...

متن کاملCross-Selectivity Enhancement of Poly(vinylidene fluoride-hexafluoropropylene)-Based Sensor Arrays for Detecting Acetone and Ethanol
Two methods for cross-selectivity enhancement of porous poly(vinylidene fluoride-hexafluoropropylene) (PVDF-HFP)/carbon black (CB) composite-based resistive sensors are provided. The sensors are tested with acetone and ethanol in the presence of humid air. Cross-selectivity is enhanced using two different methods to modify the basic response of the PVDF-HFP/CB sensing platform. In method I, the...
