Hybrid polymer-inorganic membranes with varied composition of polymeric matrix were synthesized by UV-curing of a mixture of acrylic monomers with simultaneous formation of inorganic network via sol-gel reaction of tetraethoxysilane. Composition of polymeric counterpart was varied by changing the ratio of hydrophilic and hydrophobic monomers, whereas the content of inorganic counterpart was maintained constant. Morphology, thermal behavior and water uptake of membranes were investigated.
Polymeric materials are exposed to high temperatures that results in lowering of the film integrity. A blend of an epoxy resin with the silicone acrylate resin was developed to provide high heat resistance UV cured coatings. Earlier siliconized epoxy coatings had been developed by conventional curing. But due to environmental awareness, high productivity rate, low process costs and energy saving UV curable coatings are enjoying considerable growth.
