摘要：
To improve the piezoelectric properties of polyvinylidene fluoride (PVDF), silicon dioxide (SiO2) in-situ doped PVDF composite nano fiber membranes were prepared via the sol-gel method and high-voltage electrospinning technology with PVDF and ethylsilicate (TEOS) as raw materials, N, N-dimethyl formamide (DMF) and acetone as mixed solvent. Surface micromorphology, chemical composition, mechanical and piezoelectric properties of the nanofiber membranes were compared and analyzed. Results show that the mass and thickness of composite nanofiber membranes ascended with the increase of TEOS. Electrospinning converted part of the α phase in PVDF to β phase, and the β phase content of pure PVDF nanofiber membrane was (31.42±0.62)%, which was 1.54 times higher than PVDF powder. Moreover, the content of β phase was further improved by in-situ doping of nano-SiO2, and peak value of (42.59±0.62)% was achieved when the mass of TEOS was 1.643 g. With the increase of nano-SiO2, both tensile force and output voltage of composite nanofiber membranes demonstrated an increase-decrease trend. In addition, when the mass of TEOS was 1. 643 g, SiO2 in-situ doped PVDF nanofiber membrane exhibited the highest tensile strength and output voltage, which were (8.03±0.19) N, and (2.33±0.13) V, respectively. © 2021, Periodical Agency of Journal of Textile Research.
