I have to prepare silica based thin films by solgel method. The sample has already been calcined on high temperature. I have tried glass substrate but they are not binding to it well. Can someone suggest me a better substrate for their study in aqueous medium or some binder that can help their binding to substrate.
You can trying a pre-treatment, You'll treat the substrate electrochemically in order to increase the rugosity, such can increase the surface energy and that will enhance their binding to the substrate. Bur I dont work with Sol-Gel but I know that, if you have a poor adhesivity you ever try to increase the rugosity. Or maybe you need to use an agent that promoves the binding between the surfaces.
There are silane coupling agent and resin adhesives used on silica based materials that can help you! However, I don't know if you could use only reading your question...
