Sep 29, 2016

The inorganic materials constituting the polyimide-inorganic hybrid material are various. Including ceramics, silica, clay, molecular sieves and the like. Generally, the inorganic material is dispersed in the form of a dispersed phase in the polyimide matrix to form a phase-separated inorganic phase. The inorganic material may be introduced into the polyimide in the form of ultrafine powder or may be blended with the polyimide precursor solution in a certain precursor form to be converted to the corresponding inorganic phase. The so-called sol-gel method.
