Abstract
Provided are organic-inorganic hybrid polyamic ester, method of fabricating the same, and method of fabricating a film thereof. The polyamic ester is formed by chemically reacting an inorganic precursor containing inorganic and/or metal element with a polyamic acid having two carboxyl acid of good reactivity per a polymer repeating unit. The inorganic alkoxide is hydrolyzed to be the corresponding inorganic hydroxide. The hydroxyl group is reacted with the carboxylic acid of the polyamic acid and with the hydroxyl group of the other inorganic hydroxide. Therefore, the polyamic ester can steadily include more inorganic materials. The content amount of the inorganic material is relatively high, so that the polyamic ester may have superior refractive index, chemical and heat resistances.
