Ag–Se nanostructure films were deposited on a–Se/nylon templates by a template-engaged reaction. Firstly, amorphous selenium (a–Se) was deposited on nylon by employing the chemical bath deposition method while using H2SeO3 and Na2SO3 solutions with an increasing selenium deposition time. Then, these a–Se/nylon templates were exposed into AgNO3 solution at ambient temperature and pressure. The Ag–Se/nylon nanocomposites surface morphology, elemental and phase composition, and optical properties were monitored depending on the selenium deposition time on nylon. Scanning electron microscopy (SEM) analysis confirmed the development of a very complex surface composed of pyramidal-like sub-micron structures, agglomerates, and grid-like structures. Energy dispersive spectroscopy (EDS) proved the presence of carbon, oxygen, nitrogen, selenium, and silver. SEM/EDS cross-sectional analysis confirmed the multilayer character with different individual elemental composition in each film layer. X-ray diffraction analysis revealed a polycrystalline Ag2Se phase with or without metallic Ag. The RMS value obtained from atomic force microscopy varies from 25.82 nm to 57.04 nm. From the UV-Vis spectrophotometry, the direct optical band gaps were found to be 1.68–1.86 eV. Ag–Se/nylon composites exhibit high refractive indices in the near infrared region.

“…with the distance. By using AFM, many scholars have studied the characteristics of adhesion force between particles and high temperature gas-cooled reactors (HTGR), such as Beach [11], Drelich [12], Gorb [13], Mokgalapa [14], et al Their research shows that the adhesion force obtained by AFM test is 100-1000 times smaller than that calculated by JKR model. Because AFM test will get the sum of all forces between particle and sample, Schaefer discussed the influence of water vapor pollution in the process of measuring adhesion, and pointed out that when there is water vapor on the wall, the adhesion between particle and wall will be reduced [15].…”

Gas insulated transmission lines (GIL) have a wide application prospect in special occasions such as cross terrain power transmission. Metal particle pollution is an important reason for the low insulation performance of GIL. When micron metal particles (MMPs), which are the most common metal particles in engineering, adhere to insulators or high-voltage electrodes, the insulation performance will be reduced. Based on that, this paper mainly studied the static adhesion characteristics of MMPs. Firstly, the static adhesion models and their applicable conditions were introduced. Then, through the atomic force microscope (AFM) test, the adhesion force of MMP-electrode and MMP-insulator was obtained. The test results show that MD model should be used to calculate the adhesion force of MMP-electrode and MMP-insulator. In addition, the adhesion force presents the characteristics of random distribution due to the surface asperities of MMPs and samples. Therefore, according to the test results, this paper introduced the equivalent adhesion work, which is a random variable, and obtained the probability distribution model of equivalent adhesion work. Finally, the distribution of adhesion force was obtained. The above research results provide guidance for inhibiting the adhesion of metal particles in GIL.INDEX TERMS GIL, micron metal particles, adhesion model.
