【摘要】 采用电纺及热亚胺化技术制备了聚酰亚胺/Ag纳米纤维复合材料,用X-射线衍射(XRD)、扫描电子显微镜(SEM)及透射电子显微镜(TEM)对纤维表面形貌及结构进行了表征,并研究其电学性能及力学性能.结果显示,随着银含量的增加复合纳米纤维膜的电导率逐渐提高.当Ag的质量分数为35%时,复合纳米纤维膜的导电率为2.8μs/cm,同时其拉伸强度高达240 MPa。更多还原

【Abstract】 Silvered/polyimide composite nanofibres were fabricated from the poly(amic acid)(BPDA-BPA-ODA) by electrospinning and thermal imidization.The morphology and structure of electrospun fiber mat were charac-terized by X-ray diffraction,scanning and transmission electron microscopes.Experimental results show that the electronic conductivity of the composites increased with increase of silver content and reached up to 2.8 μs/cm and 240 MPa,respectively with silver content of 35%.更多还原
