Summary: By reasonable coating structural design, a PDMS modified PU/Sm2O3 composite coating with super-hydrophobic and near-infrared absorption properties was successfully prepared. Adjusting the mass ratio of Sm2O3 and nano-SiO2 can achieve super-hydrophobic properties of the coating, while adding Sm2O3 can reduce the reflectivity of near-infrared light.

Summary: In this study, Mg2+ was doped in nanoporous SiO2 nano-particles to modulate the infrared emissivity of intrinsic SiO2. The effects of Mg doping on the crystallinity, morphology, infrared emissivity, and radiative cooling properties were investigated. The results showed that Mg doping induced cristobalite na-nocrystals, transformed the morphology, and improved the infrared emissivity. The Mg-doped SiO2 coatings exhibited high solar reflectivity and significantly improved radiative cooling capacity.

Summary: In this study, a composite coating with low infrared emissivity and high radar wave transmittance was prepared by sol-gel method. By adjusting the thickness of the surface modification layer of the floating aluminum powder, the dielectric constant and dielectric loss tangent values of the composite coating were significantly reduced. At a TEOS addition amount of 1g, a composite coating with an infrared emissivity of less than 0.6 was obtained.

Summary: In order to reduce the emissivity and enhance the mechanical properties of a hydrophobic low infrared emissivity composite coating, a dispersant, adhesion enhancer, and defoamer were utilized. The dispersion state of the fillers, interface structure, and surface condition of the coating were improved. The influences of these additives on the microstructure, emissivity, glossiness, hydrophobic property, adhesion strength, and impact strength of the coating were systematically studied.

Summary: By preparing Al-SiO2 nanoparticle composite films with varying SiO2 volume content, this study achieved a low infrared emissivity of 0.12 and high visible absorptivity of 0.67 when the SiO2 volume content was optimized at 6.9%. The compatibility issue between infrared stealth and visible stealth was resolved through the simultaneous low infrared emissivity and high visible absorptivity of the Al-SiO2 nanoparticle composite film.

Summary: This paper investigates the silicone rubber coating containing self-healing microcapsules with tung oil and tests its properties. By adjusting the size and content of the microcapsules, as well as adding nano-SiO2, the self-healing and mechanical properties of the coating are improved. The study shows that the nano-SiO2 forms a double network structure with the silicone rubber, effectively enhancing the mechanical properties of the coating.
