Researchers found that the newly developed hydrosilylated water-based organosilicone coatings have excellent anti-fouling properties, allowing water, ethanol, muddy water and other liquids to bead cleanly and oily marks to be easily wiped off.

Research proves that these coatings maintain their anti-fouling performance even under extreme conditions such as high temperatures, UV radiation and chemical corrosion, indicating high durability and longevity of the materials. Source: sevector - adobe.stock.com

Under the background of “Dual Carbon” strategy, the coating technology of silicon-based materials replacing carbon-based materials has become a research hotspot. Owing to high-viscosity characteristic of raw materials involving divinyl-terminated polydimethylsiloxane (ViPDMSVi) and reinforcing components, existing approaches for the preparation of organosilicon coatings by hydrosilylation still consume a large amount of organic solvents, causing environmental pollution and inconsistent with the low-carbon strategy. Herein, a robust strategy to prepare hydrosilylation waterborne organosilicon coatings via rational design of the emulsification system to obtain two-component aqueous emulsions is reported. In this strategy, two reactive organosilicon surfactants were synthesized and compounded with corresponding anionic surfactants for emulsification of vinyl organosilicon components and polymethylhydrosiloxane (PMHS), respectively.
