Abstract:
1. A film substrate having a thickness of 30 to 500 μm, prepared by a process comprising the steps of: a) preparing a mixture solution by mixing an organic polymer, which has a water solubility of 0 to 5 g based on 100 g of 25° C. water and has an acetone solubility of 25 to 100 g based on 100 g of 25° C. acetone, and a reactive metal compound under a reaction accelerating condition, so as to form a condensation polymer from said reactive metal compound and a hybrid from said organic polymer and said condensation polymer, b) casting the mixture solution on a substrate; and c) drying the mixture solution on the substrate to obtain the film substrate having the thickness of 30 to 500 μm, wherein the reactive metal compound is at least one pair of a reactive metal compound having two substituents capable of being hydrolyzed per one metal atom and a reactive metal compound having three substituents capable of being hydrolyzed per one metal atom.
