摘要:

通过将苯并噁嗪、聚丙烯腈(PAN)和乙酰丙酮铁共同静电纺丝的方式制备了柔性良好的碳纳米纤维薄膜。结果表明,引入结构设计的苯并噁嗪可以有效地将N、O、S等杂元素引入碳纳米纤维薄膜,从而有效地提高电极的赝电容特性及电解质对电极的浸润性。并在此基础上,进一步将环境友好且赝电容特性明显的Fe3O4沉积在所得碳纳米纤维薄膜上,最终制备了电化学性能优异的柔性电极材料Fe3O4@BENCNFs,三电极测试结果表明,当电流密度为1 A/g时,其质量比容量高达160.1 F/g。

Abstract:

A carbon nanofiber membrane with good flexibility was prepared through electrospinning with a mixture of benzoxazine, PAN and iron acetylacetonate. The results indicated that the N, O and S heteroatoms were successfully introduced into the as?prepared carbon nanofiber membrane through electrospinning in terms of the chemical structure designed benzoxazine, and these introduced heteroatoms effectively enhanced the pseudocapacitance of the electrode and its wettability with the electrolyte. Furthermore, eco?friendly Fe3O4 with excellent pseudocapacitance was deposited on the surface of the carbon nanofiber membrane to obtain a flexible supercapacitor electrode material (Fe3O4@BENCNFs) with excellent electrochemical performance. The three?electrode test results indicated that the Fe3O4@BENCNFs achieved a specific capacity of 160.1 F/g at a current density of 1 A/g.

Key words: electrospinning, carbon nanofiber membrane, benzoxazine, electrochemical property
