The crisis of contamination that leads to the accumulation of dust particles on insulation equipment and electrical insulators has disrupted the electricity grid. Electric discharge on infected insulators in wet conditions is a serious threat to the reliability of the grid, which can lead to grid failure and blackout. In this regard, the importance of hydrophobic and dustproof coatings in the electricity industry has increased in recent years. In this paper, silica nanoparticles in the silicon rubber matrix were used to coat ceramic insulators to decrease the environmental impact of dust and moisture on the insulator’s coatings. One of the essential properties of these coatings is their hydrophobicity to prevent possible problems in power transmission. With this regard, nanocomposites were applied to 70 kN insulators and the tests were designed according to the available standards. The performance of these nanocoatings was evaluated by the implementation of electrical, salt fog, and hydrophobicity tests. Finally, the nanocomposite sample containing 3 wt % silica was recognized as the best one.

This research aims to determine the influence of fundamental, applied, developmental research and Nanofabrication (NanoFab) centers on the final outcomes achieved by research and development activities, implying product development and value creation in nanotechnology. Data were collected through library studies and field studies in this study and research factors were also identified. To confirm the collected factors, structural equation technique and Smart PLS software were used and after confirming the research factors, the collected data were analyzed using fuzzy inference method and MATLAB software. The achieved results indicated that this field had the most performance despite the minimal influence of fundamental research on the final results of research and development activities and developmental research, while NanoFabs had the poorest performance with the highest influence on the final results of research activities. It is possible to conclude according to the research results that research and development activities at the fundamental and applied levels cannot easily be connected to the end ring, i.e., industry without NanoFab centers, and provide the final product and create value. Furthermore, providing NanoFab or NanoFabs with emphasis on the development of nanomaterial can significantly affect the development of renewable energies.
