Abstract
Inorganic membranes such as zeolite membranes or other molecular sieve membranes can be provided by using silicone polymer material as starting material. A thin film zeolite membrane or a thin film membrane formed of interlocking zeolite crystals can be provided. Water soluble or water insoluble silicones can be treated in a basic solution under conditions and with an appropriate structure directing template, suitable aluminum content and at a temperature that is appropriate for growing a desired inorganic crystal framework. The continuous thin film membranes or interlocking crystal membranes can be formed on the sides of a reaction vessel, on the surface of the solution or on the surfaces of substrates introduced into the vessel.
