- Organic-Inorganic Hybrid Having Low Coefficients of Thermal Expansion and Method for Making the Same

摘要

The present invention relates to a process for preparing a silica-metal oxide solution, which comprises dissolving a silsesquioxane oligomer and a metal oxide in a solvent to prepare a silica-metal oxide solution; Adding a poly (amic acid) solution to the silica-metal oxide solution and reacting; And a step of heating the obtained solution. The present invention relates to a method for producing an organic-inorganic hybrid, and an organic-inorganic hybrid, wherein inorganic particles are uniformly dispersed and can be controlled in size Excellent thermal properties.;
