Abstract
A polyimide film includes a polyimide, a carbon black present in a quantity between about 0.5 wt % and about 5 wt %, and a fluorine-containing polymer present in a quantity between about 15 wt % and about 40 wt %. The polyimide film can be a single-layer film or a multi-layer film, and has a low dielectric constant and low gloss.
Claims12
A base polyimide film comprising:
- a polyimide derived from condensation reaction of diamine monomers and dianhydride monomers;
- a carbon black present in a quantity between about 0.5 wt % and about 5 wt % based on a total weight of the base polyimide film;
- and
- a fluorine-containing polymer present in a quantity between about 15 wt % and about 40 wt % based on the total weight of the base polyimide film;
- wherein the base polyimide film has a dielectric constant Dk less than about 3.05, and a gloss equal to or less than about 10.
