Abstract

It has been found that the hybrid materials are a compatible matrix for numerous organic compounds, such as organic dyes, laser dyes, and compounds that exhibit photo-chromic behavior and many more The epoxy-silica system seems to be an excellent matrix for organic dyes and a hybrid material suitable for to be used as coating on glass substrates with good adhesion properties. This work presents a systematic study of the effects of the different amount of using rhodamine 6G as dye on the structure and properties of epoxy–silica hybrids coatings synthesized by the sol-gel process. We have taken advantage on the high solubility of organic dyes in a hybrid organic–inorganic epoxy resin–silica (epoxy–SiO2) matrix to obtain homogeneous, hard and high optical quality red color films on glass substrates. The effects of the content of rhodamine 6 G on the optical and thermal properties of epoxy-silica hybrid films were also examined. Epoxy resin DER 332 cured with an amine (4,4 diamino diphenyl methane) was used as organic component and tetraethyl orthosilicate (TEOS) was used as precursor of the inorganic component. The results showed that at a concentration of rhodamine 0.05% coatings retain adhesion properties similar to coatings without colorant and the coatings are uniform and free of defects. These coatings have the potential to be used as filters and ornamental coatings.
