具有高机械强度和良好介电性能的柔性材料是现代电子产品非常需要的。本研究通过将无规PVDF纳米纤维和取向的co-PI纳米纤维逐层热压复合，制备了全有机PVDF/PI纳米纤维增强复合材料。研究了PVDF/PI复合材料的介电性能和力学性能。结果表明，取向的共聚酰亚胺纳米纤维的机械性能得到了极大的提高，介电常数继承了PVDF固有的良好介电性能。这些全有机PVDF/PI复合材料具有优异的机械强度和良好的介电常数可调，可用于柔性嵌入式电容器，并可进一步用作聚合物基体制备高介电聚合物基复合材料。
Flexible materials with high mechanical strength and good dielectric properties are highly desired for modern electronics. In this research, all-organic PVDF/PI nanofiber-reinforced composites were fabricated by layer-by-layer hot-pressing the random PVDF nanofibers and aligned co-PI nanofibers. Dielectric and mechanical properties of the PVDF/PI composites were investigated. Results showed that the mechanical properties were highly enhanced by the aligned co-PI nanofibers and the dielectric permittivity was inherited from the intrinsic good dielectric properties of PVDF. These all-organic PVDF/PI composites with excellent mechanical strength and good tunable permittivity can be used for flexible embedded capacitors and can be further employed as the polymer matrix for preparing high dielectric polymer–matrix composites.
