Cationic Core/Shell Polysiloxane Acrylate Emulsion: Synthesis, Film Morphology, and Performance on Cotton Pigment Coloration.

In this paper, acrylate-terminated polysiloxane was synthesised and used as raw materials for the synthesis of cationic core/shell polysiloxane acrylate emulsion, which was applied as binders in the pigment dyeing of cotton fabrics. The experimental results showed that: the cationic core/shell poly siloxane acrylate emulsion in this article is in nano size of 100nm. During the film formation of the emulsion, there are core-core and shell-shell fusion phenomena between the latex particles, and same poly siloxane chain aggregates on the surface of the film. When the emulsion is used in the pigment dyeing of cotton fabrics, the dyed cotton fabrics feel soft, and the soaping fastness and dry/wet rubbing fastness meet the national quality requirements, as soaping fastness can reach grade 4 ~ 5, dry rubbing fastness can reach grade 4 ~ 5, and wet rubbing fastness can reach grade 4.

Sustainable Waterborne Vanillin-Eugenol-Acrylate Miniemulsion with Suitable Antibacterial Properties as Substitutes for Styrene-Acrylate Emulsion

In this work, we have prepared solvent-free, facile synthesis of renewable aromatic monomers, double bond modified vanillin (DV) and double bond modified eugenol (DE). The resulting DV and DE were...

Hydrophobicity and corrosion resistance of waterborne fluorinated acrylate/silica nanocomposite coatings

This study aims to improve the hydrophobic properties and corrosion resistance of fluorinated acrylate coatings. The surface of nano-SiO2 was modified by the silicone coupling reagent (KH-570), and the reactive functional groups were introduced to modify fluorinated acrylates. The functionalized SiO2-modified waterborne fluorinated acrylate emulsion was prepared by free polymerization with dual initiators. The structure of the polymer was analyzed by Fourier transform infrared spectroscopy (FTIR), nuclear magnetic resonance spectro-meter (1H-NMR), X-ray photoelectron spectroscopy (XPS) and Waters gel chromatography (GPC). The properties of the films and coatings were analyzed by contact angle, atomic force microscopy, scanning electron microscopy, and electrochemical analysis. The results showed that the contact angle reached 120° when the SiO2 content was 3%, the electrochemical impedance value reached 1.49 × 107 Ω·cm2, and the pencil hardness was 3H.
