Abstract:
Polymer nanocomposites have a considerable industrial application because of their low cost enhance durability, mechanical, and thermal characteristics. Focus of this research work is on the preparation of SiO2 NPs through sol-gel method and their incorporation as nanofiller as the 5%, 10%, 15%, 20% and 25%into the polytetrafluoroethylene (PTFE) polymer for the fabrication of matrix, to obtained a polymer nanocomposites with unique combined properties of filler and matrix because these nanocomposites has immense importance in various field such as defense, electronics, military. Initially SiO2NPs will be synthesized through sol-gel method. SiO2NPs were characterized using XRD spectroscopy. The XRD measurements of silica confirmed that the silica is predominantly an amorphous solid. The diffraction peak at 2? = 27 confirms the formation of amorphous silica. These can be appropriately marked by various peaks corresponding to silica (JCPDS CARD#01-081-0067). Current results confirmed the successful synthesis of SiO2NPs. Then these NPs are incorporated in PTFE matrix and the structural elucidation of PTFE/SiO2was analyzed through FTIR and XRD. The structural changes upon the PTFE revealed the efficient interaction of SiO2 with the polymers. XRD analysis revealed the enhancement in the crystallinity of PTFE. Dielectric constant and dielectric lossproperties of the silica NPs filled PTFE composites was carefully find out by varying the filler concentration from 5 to 25wt% in 5wt% interval meter is used for this measurements and was measured at 100Hz to 1MHz frequency at room temperature
