Claim:
1. A composition for preparing a polyimide-inorganic particle composite comprising: a reaction product of a tetracarboxylic dianhydride mixture and a diamine, and a precursor of an inorganic particle, wherein the precursor of an inorganic particle is selected from an alkoxide, ester, acetylacetonate, halide, or nitride of Si, wherein an amount of the precursor of an inorganic particle is about 8 percent by weight to about 18 percent by weight based on the weight of the reaction product of a tetracarboxylic dianhydride mixture and a diamine, wherein the tetracarboxylic dianhydride mixture comprises a tetracarboxylic dianhydride represented by Chemical Formula 5, and a tetracarboxylic dianhydride represented by Chemical Formula 7, and wherein the diamine comprises 2,2′-bis(trifluoromethyl)benzidine:
