“…and, "Does there exist an optimal film structure attainable through deposition control?". The question of optimal filler material quantity has been examined by a number of investigators in various separate disciplines [12,13,14,15]. One model, coined General Effective Media (GEM), was developed that enabled the calculation of the composite resistivity of a material assuming a random dispersion of equally-sized constituents [16,17].…”

Electrical contact materials deposited via thin-film processes enable the structuring of interfaces that optimize electrical contact performance. The performance gains are accomplished by structuring the contact material such that a conductive pathway is always present in the composite, a phenomenon related to the percolation threshold. The relationship between film composition and percolation threshold was explored by combined three-dimensional contact area and resistance modeling as well as experimental efforts. An optimal composite structure was found based on deposition parameters and compositional phase selections contacts, contact resistance, conductivity, modeling

“…Alumina oxide (Al 2 O 3 ) is widely used in the fields of ceramics, optics, the chemical industry, machinery and microelectronics because of its excellent optical properties, high mechanical strength and hardness, good insulation, wear resistance, corrosion resistance and chemical inertia. 23 In addition, Al 2 O 3 is a good infrared absorber, especially in the mid-infrared region, [24][25][26] thus Al 2 O 3 may be a good candidate for combined photothermal materials.…”

As a functional textile, photothermal textile materials are receiving more and more attention. A composite yarn was prepared by coating polyvinyl butyral/zirconium carbide/alumina oxide on the surface of polyester yarn through a sizing coating method with the aim to provide a textile substrate with controlled photothermal efficiency. The Box–Behnken design combined with response surface analysis and regression method was used to study the effects of input variables (polyvinyl butyral, zirconium carbide and alumina oxide concentration) on the temperature of the fabric made of polyester/polyvinyl butyral/zirconium carbide/alumina oxide composite yarn under infrared light irradiation. It was found that the effect of polyvinyl butyral and zirconium carbide content on the fabric surface temperature was more significant than that of alumina oxide content. The established regression model could predict the response value (fabric temperature) precisely. The optimal conditions for preparing the polyester/polyvinyl butyral/zirconium carbide/alumina oxide composite yarn were obtained by response surface analysis: 5.9% polyvinyl butyral, 5% zirconium carbide and 0.5% alumina oxide. The structure and properties of the yarn prepared under the optimal conditions were characterized. The results showed zirconium carbide and alumina oxide deposited on surface coating without obvious deterioration of thermal stability and tensile strength. The near-infrared light absorption rate of the composite yarn reached 96.71% and its surface temperature reached 104.0°C after 180 s irradiation under an infrared lamp. The photothermal temperature can still reach 101.5°C after 20 cyclings. The excellent photothermal conversion capacity indicates the polyester/polyvinyl butyral/zirconium carbide/alumina oxide yarn can realize solar energy utilization and be applied in heat management textiles.
