Splet15. avg. 2024 · In contrast, when PDMS-PU was not used, fumed silica particle coatings were unable to impart hydrophobicity to the fabric, and drastically reduced abrasion resistance of the base fabric. We deduce that our polymer dispersion acts as a bridge to hold the silica particles as a top layer to enhance the hydrophobicity while showing … Spletpanied by chemisorption of the PDMS decomposition products onto the silica surface.

PDMS is a common surfactant and is a component of defoamers. PDMS, in a modified form, is used as an herbicide penetrant and is a critical ingredient in water-repelling coatings, such as Rain-X. Dimethicone is used in the active silicone fluid in automotive viscous limited slip differentials and couplings. Spletpanied by chemisorption of the PDMS decomposition products onto the silica surface. The preliminary modification of fumed silica by phosphorus oxides had a substantial effect on the mechanism of the thermal destruction of PDMS and led to the depolymerization of adsorbed macromolecules at lower temperatures (Bogatyrov and Borysenko 2000).
