Summary: In this article, CTFE-based fluorocarbon composite latexes and their coatings were successfully prepared using a new environmentally friendly method based on MFWPU dispersion. The MFWPU dispersion acted as a stabilizer and microreactor, providing the composite coating with excellent self-healing performance and adhesion. The introduction of a dynamic disulfide bond and carbon-carbon double bonds in the polyurethane dispersion enhanced the scratch self-healing performance and compatibility of the coating. The research results have important implications for the structural design and application of waterborne fluorocarbon functional coatings in the future.

Summary: A repeatable and environmentally friendly method was used to prepare a hydrophobic surface with photocatalytic features. Titanium dioxide nanoparticles and fluorinated ethylene propylene (FEP) resins were applied on an aluminum substrate using layer-by-layer and mixing methods. The prepared films were analyzed and the photocatalytic activities were explored. The hydrophobicity and photocatalytic performance were better in the samples with one layer of titanium dioxide and three layers of FEP in the layer-by-layer method, and in the sample containing 10 wt% TiO2 in the mixing method.

Summary: Antireflective and self-cleaning coatings have gained attention for their wide applications, but they face challenges such as poor performance optimization, mechanical stability, and environmental adaptability. The development of high-performance coatings with satisfactory mechanical stability remains a challenge. A biomimetic composite coating (BCC) was prepared, which showed improved antireflective and self-cleaning properties, as well as remarkable mechanical stability and acid resistance.

Summary: By hybridizing TiO2 photocatalyst with CaCO3 as the wall material and using linseed oil as the core material, self-cleaning and self-repairing microcapsules were produced using in-situ precipitation. The microcapsules were evaluated for their morphology, chemical composition, thermal stability, and self-cleaning and self-repairing properties. Results showed that the microcapsules had a rough and spherical surface, along with excellent thermal stability and repeatability. Increasing the dosage of microcapsules significantly increased the degradation rate of methylene blue, while the self-repairing effect of micro-cracks became more evident. The optimal microcapsule dosage was found to be 7.0 wt%.

Summary: Different membrane compositions were designed to improve the self-cleaning and low emissivity of the membrane. The WO3/Mo/CrNi/TiO2 composite film prepared by magnetron sputtering technology showed complementary effect with different argon/oxygen ratios of TiO2 layer and film thicknesses. The microstructure characterization proved that the self-cleaning function of the composite film was determined by the photocatalytic properties and superhydrophilic properties of the TiO2.

Summary: The Co/TiO2 micro- and nano-composite coatings were compared for their tribological properties and corrosion behavior. It was found that nano-composites had smoother worn surfaces and stable oxide layers, while micro-composites showed lower volume loss and higher friction coefficients. Additionally, the co-deposition of micro/nano-particles significantly improved corrosion resistance, with nano-composite coatings exhibiting better corrosion resistance than micro-composite films.
