Abstract:
1. A process for the production of a layered inorganic/organic composite material, said layered inorganic/organic composite material consisting of a predominantly inorganic material layer, selected from the group consisting of lead glass, phosphate glass and borate glass, and a polymeric layer, the process comprising providing a predominantly inorganic material and a polymeric material, wherein the melting point of the predominantly inorganic material is below 500° C., melting the predominantly inorganic material and the polymeric material, and coextruding the predominantly inorganic material and the polymeric material in order to form the composite material by an extrusion process, wherein the composite material, including both the inorganic material layer and the polymeric layer, is subjected to an orientation process during discharge of the extrusion process, and wherein the thickness of the inorganic material layer is between 5 to 25 μm.
