Fabrication and performances of preceramic polymer-based high-temperature High emissivity coating

Band gap and oxygen vacancy engineering of honeycomb‐like CuFe2O4 spinels toward enhanced high infrared emissivity

“…Figure 7D–F illustrates the surface macroscopic digital photographs, microstructures, and cross sections of the coatings after thermal cycling. As expected, the coating has no cracks, peeling, or obvious distortion even after 15 thermal cycles at a high temperature of 800°C (Figure 7D,E), which is even better than several previous reports, 3,22 suggesting its enormous applications in the coating field. The cross‐section image visualizes that the coating is merely widened by about 8 µm after thermal cycling (Figure 7F).…”

“…In view of less pollution and energy conservation, infrared heating and drying technique is being utilized in many industries. Hereby, high infrared radiation materials, as the main component of infrared radiation coatings, have been widely applied in high‐temperature furnaces, infrared heaters, aerospace fields, and electronic and electrical industries due to their excellent radiation power, durability to high‐temperature oxidation, and high infrared emissivity 3–5 . As a consequence, there is an increasing demand for high infrared emissivity materials.…”

Investigation of thermal control in phase-changing ABO3 perovskites via first-principles predictions: general mechanism of emittance

“…Phase-change thermal-control materials present intriguing challenges and hold great promise for use in thermophotovoltaic systems, 1,2 smart windows, 3,4 building insulation, 5 spacecraft, 6 multispectral thermal camouflage, 7 and thermal protection and insulation, [8][9][10] due to their extraordinary spontaneous and temperature-tunable emittance. According to Wien's displacement law, 11 the ideal emittance and waveband of a thermal-control material will vary for different working temperatures and applications.…”

Field Electron Emission Experiments with Cold-Sprayed Cu-SiC Composite Coatings

“…The most frequently used materials for films and coatings are-(i) different forms of carbon (e.g., graphene [25], diamond [26][27][28], carbon nanofibers [29] or nanotubes [30]) deposited by dip coating [25], plasma-enhanced chemical vapor deposition (PECVD) [26,29], sludge printing [30] or electrodeposition [27,28], and (ii) complex alloys and materials (e.g., ZnIn 2 S synthesized from zinc nitrate (Zn(NO 3 ) 2 •6H 2 O), indium nitrate (In(NO 3 ) 3 •H 2 O) and thiourea ((NH 2 ) 2 CS) [31], perovskites as SrTiO 3 [32], composite coating made from mixtures of CeO 2 , B 4 C, and PSON (mixture of polysiloxane and polysilazan) [33]) deposited by hydrothermal [31] or chemical [33] synthesis, or vacuum electron beam physical vapor deposition (EBPVD) technique [32,34]. Some of the processes are time consuming, such as chemical synthesis with long-time curing for 3 days [33], hydrothermal synthesis with a duration of 15 h [31]. Some others are expensive, such as the EBPVD [32,34] or PECVD technique [26,29].…”
