  Abstract

Polyimide (PI) nanofiber membranes (NFMs) via electrospinning demonstrate widespread applications with an intrinsic drawback of lower mechanical performance, which could be improved with multi-wall carbon nanotubes (MWCNTs). PI NFMs was fabricated via a simple thermal induced imidization of polyamic acid (PAA) NFMs and MWCNTs/PI composite NFMs were also investigated on the effect of MWCNTs on morphology, mechanical performance, and its possible carbonization. Such simply thermal induced imidization of PAA demonstrates successfully to be PI, and small amounts of MWCNTs could reduce the diameter and distribution of MWCNTs/PI nanofibers, and coarse and granular-like surface appeared on MWCNTs/PI composite nanofibers as the MWCNTs was increased up to 1.0 wt.%. Notably, addition of MWCNTs improved thermal stability and mechanical performance of MWCNTs/PI composite NFMs, but it lowered the mechanical performance of such composite NFMs at higher carbonization temperatures, which makes its carbonized NFMs even more inclined to be fragile and fracture.
