Claims13
A polyimide polymer, comprising a repeating unit represented by formula (I):
- wherein R1 and R2 are the same or different from each other, and are each independently an ether group, an ester group, an amine group or other heteroatom chains, an alkyl group, an alkenyl group, an alkynyl group, an aryl group or other carbon chains, Ar is a tetravalent organic group containing aromatic ring.
A polyimide mixture, comprising:
- a polyimide precursor, wherein a polyimide polymer is dissolved in a first organic solvent to obtain the polyimide precursor, and the polyimide polymer comprises a repeating unit represented by formula (I):
- wherein R1 and R2 are the same or different from each other, and are each independently an ether group, an ester group, an amine group or other heteroatom chains, an alkyl group, an alkenyl group, an alkynyl group, an aryl group or other carbon chains, Ar is a tetravalent organic group containing aromatic ring;
- and
- a silica containing solution, wherein a plurality of silica particles are dispersed in a second organic solvent to obtain the silica containing solution.
