POLYAMIC ACID-SILICA HYBRID COMPOSITION MANUFACTURED BY USING A SURFACE-TREATED SILANE SOL, POLYAMIDE-SILICA HYBRID FILM, AND A MANUFACTURING METHOD THEREOF

摘要

PURPOSE: A manufacturing method of a polyamic acid-silica hybrid composition is provided to improve compatibility and mixing performance by using a silane sol coupled with a polyamic acid to the surface thereof.;CONSTITUTION: A manufacturing method of a polyamic acid-silica hybrid composition comprises a step of manufacturing a polyamic polymer with a silane terminal by reacting a polyamic acid and silane coupling agent; a step of putting an organic solvent, diluted water, and acid catalyst agent into alkoxy silane for a hydrolysis and condensation reaction and putting in a silane coupling agent to manufacture a silane sol; a step of manufacturing a silane sol coupled with a polyamic acid to the surface thereof; and a step of manufacturing a polyamic acid-silica hybrid composition by mixing a silane sol and polyamic acid polymer coupled with the polyamic acid to the surface thereof.;COPYRIGHT KIPO 2013;[Reference numerals] (AA) Anhydride end PAA
