Free-standing, flexible, composite films of poly(vinylidene fluoride)/poly(3,4 ethyelenedioxythiophene):poly(styrelenesulfonate) (PVDF/PEDOT:PSS) were deposited. The films were characterized using Field Emission Scanning Electron Microscopy, X-Ray Diffraction, Raman, and Fourier-transformed infrared spectroscopic studies. Enhancement in the conductivity with an increase in the concentration of the additives was observed. The electrical conductivity of the high resistive PVDF films increased to ∼10−3Scm−1 with the addition of a maximum of 1.7 mL of a 1.3 wt.% aqueous dispersion of PEDOT:PSS. An increase in the conductivity of the films with temperature was observed, indicating semiconducting nature. At room temperature, the conductivity of the composite films was found to be in the range of ∼1.3 × 10−4Scm−1 to ∼7.3 × 10−3 Scm−1. The conductivity of the composite films was found to follow the Mott Variable Range Hopping model of conduction.

调节聚(偏二氟乙烯)/聚(3,4 亚乙基二氧噻吩):聚(苯乙烯磺酸盐)的自立式柔性复合膜的电导率

沉积了聚(偏二氟乙烯)/聚(3,4 亚乙基二氧噻吩):聚(苯乙烯磺酸盐)(PVDF/PEDOT:PSS)的独立式柔性复合膜。使用场发射扫描电子显微镜、X 射线衍射、拉曼和傅里叶变换红外光谱研究表征薄膜。观察到电导率随着添加剂浓度的增加而增强。高电阻 PVDF 薄膜的电导率增加到~10 -3 Scm -1添加最多 1.7 mL 的 1.3 wt.% PEDOT:PSS 水分散体。观察到薄膜的电导率随温度增加,表明具有半导体性质。在室温下,该复合膜的导电性被发现是在〜1.3×10的范围内-4 SCM -1至〜7.3×10 -3 SCM -1。发现复合膜的导电性遵循莫特可变范围跳跃传导模型。
