Coating material for multifunctional superphobic layers

A family of innovative composite zeolite materials and methods for making the same are disclosed. Zeolites 3A and 13X have been incorporated into hybrid polysiloxane polymers to form composite materials which are useful as membranes for separating a variety of gaseous and liquid materials. Thermal curing, thermal drying and UV curing were utilized to initiate polymer crosslinking reactions and bond the polymers to zeolite surfaces. Thin film samples exhibited nitrogen adsorption as high as 126 cc/g and specific surface area of up to 390 m,/g. Infrared characterization spectra and TEM analysis indicated that polymeric matrices bonded to zeolite surfaces. Pore size of the composite membrane films may be tailored for specific separation applications through choice of zeolite and polymer compositions, curing method, and post-synthesis membrane treatments.

Incorporation of zeolites into hybrid polymer matrices

The invention pertains to a powder lacquer composition containing epoxy-rtive polymers as binders and epoxy-functional siloxane resins as hardeners as well as additives, if required, such as pigments and/or fillers and/or thermal stabilizers and/or additives such as flow-promoting agents and de-gassing agents, whereby the hardener is a compound which is prepared by the hydrolysis and condensation of an organo-silane R.sub.2 SiX.sub.2 of an epoxy-functionalized silane.
