Abstract
A polyimide blend nanofiber and its use in battery separator are disclosed. The polyimide blend nanofiber is made of two kinds of polyimide precursors by high pressure electrostatic spinning and then high temperature imidization processing, wherein one of the polyimide precursor does not melt under high temperature, and the other is meltable at a temperature of 300-400° C. The polyimide blend nanofiber of present invention has high temperature-resistance, high chemical stability, high porosity, good mechanical strength and good permeability, and can be applied as battery separator.
