PAN/BaTiO3电纺纤维膜的制备及其压电性能
Preparation and piezoelectricity of PAN/BaTiO3 nanocomposite membrane
摘要
Abstract
To enhance the piezoelectric of PAN, PAN membranes with different content of BaTiO3 nanoparticles were pre-pared via electrospinning method. The piezoelectricity of the membranes were tested and analyzed by homemade power generating device, SEM, FTIR, XRD and dielectric spectrometer. The results showed thatthere wasa uni-form distribution of BaTiO3 nanoparticles modified by silane coupling agent (KH550) in PAN nanofibers. The output voltage and dielectric constant of PAN/BaTiO3 nanocomposites with 12.5%BaTiO3 nanoparticles were both increased by 300%compared with that of PAN membrane, while the dielectric loss of PAN/BaTiO3 nanocompos-ites with 12.5% BaTiO3 nanoparticles was decreased by 67%compared with that of PAN membrane. The results of FTIR and XRD showed that BaTiO3 nanoparticles promoted the transformation of conformation for PAN from 31 helical conformation to zig-zag conformation,consequently enhanced the piezoelectricity of PAN.关键词
