Abstract

In the present work, the synthesis of novel nanocomposite polymer resins with silica bearing triazole functional groups was realized. Silica nanoparticles were produced by sol-gel method known as stöber process. Then the surface was modified with 1H-1,2,4-triazole to form functional silica nanoparticles. Dental nanocomposites were produced by insertion of functional nanoparticles into the Bis-GMA/TEGDMA different weight fractions. The initiator system was CQ/EDMAB:0.1:0.4 wt%, and then photopolymerization was carried out by means of LED light having wavelength of 450 nm–500 nm and power density of 1000 mW/cm2. FT-IR used to confirm the final structures of the functional nanoparticles as well as nanocomposites. The surface morphology of the materials was analyzed by SEM and thermal properties were studied by TGA. Cytotoxicity test and mechanical test were carried out to evaluate cell viability and mechanical properties of the materials, respectively. Sorption and solubility were conducted on the different formulations to obtain the mean sorption and solubility values of the materials. The test results demonstrated that the composition of the nanocomposite resins significantly changed their properties compared to control samples.
