Organic-inorgaic hybrid polyamic ester, method of fabricating the same, and method of fabricating a film thereof

A method of synthesizing an organic-inorganic hybrid polyamic ester, comprising:

• synthesizing a polyamic acid by reacting a diamine monomer with a dianhydride;
• and
• synthesizing a polyamic ester of the following chemical formula 1 by reacting the polyamic acid with an inorganic precursor,
• wherein, in the chemical formula 1, the X is an alicyclic compound or an aromatic compound, the Y is at least one selected from a group consisting of an aliphatic compound, an alicyclic compound and an aromatic compound, and the I is at least one out of an inorganic element or a metal element,
• wherein the dianhydride includes an aromatic or alicyclic compound.

A method of fabricating a film, comprising:

• dissolving a diamine monomer and a dianhydride into a first solvent and reacting the diamine monomer with the dianhydride to synthesize a polyamic acid;
• introducing an inorganic precursor into a solution containing the polyamic acid or dissolving the polyamic acid and the inorganic precursor into a second solvent to react the polyamic acid with the inorganic precursor and to synthesize a polyamic ester of the following chemical formula 1;
• and
• forming a film comprising the polyamic ester on a substrate,
• wherein, in the chemical formula 1, the X is an alicyclic compound or an aromatic compound, the Y is at least one selected from a group consisting of an aliphatic compound, an alicyclic compound and an aromatic compound, and the I is at least one out of an inorganic element or a metal element.
