<p>The present disclosure provides a composite structure and associated method for preparing a composite substrate comprising an inorganic coating that is adhered to an organic-based substrate via an adhesion promoting agent comprising a molecule having a urea moiety at one end of the molecule and an alkoxysilane moiety at the other end of the molecule. The use of adhesion promoting agent having at least one of an amine or imine moiety and an alkoxysilane moiety promotes tight adhesion of the inorganic coating to the substrate. In one embodiment, the adhesion promoting agent may have the following structure as shown in formula (I) below:
wherein X is an alkoxy group having from 1 to 3 carbon atoms; and n is a number from 1 to 5.</p> |
