Abstract
A high-modulus black matte polyimide film is provided, the high-modulus black matte polyimide film includes polyimide in an amount from 75 to 93 wt % of the high-modulus matte polyimide film, in which dianhydride and diamine are polymerized to form a polyimide precursor, and the polyimide precursor is chemically cyclized to form the polyimide; carbon black in an amount from 2 to 8 wt % of the high-modulus matte polyimide film; and liquid crystal polymer micropowder having a particle size between 2 and 10 μm and being in an amount from 5 to 20 wt % of the high-modulus matte polyimide film, wherein the high-modulus matte polyimide film has a gloss value at 60° being less than 50.
