Abstract

See full text

The present disclosure provides a method to fabricate three-dimensional transparent glass utilizing polymer plasticity, including the following steps. In step 1, synthesize polymer-glass powder composite containing dynamic chemical bonds, the bond exchange catalyst is added during the synthesis process, and then cure to obtain a two-dimensional sheet shape I, the bond exchange catalyst is used to activate a dynamic chemical bond in step 2. In step 2, shape the two-dimensional sheet shape I obtained in step 1 into a complex three-dimensional shape II under the conditions of the effect of an external force and the activable dynamic chemical bond. In step 3, pyrolyze the composite precursor at high temperature to obtain transparent glass with complex three-dimensional shape II. The present disclosure provides a method in shaping the transparent glass with complex geometries by unique polymer plasticity in lower temperature.
