Waterborne polyurethane, with a mechanical strength comparable to solvent-based types, is eco-friendly and safe, using water as dispersion medium. Polyacrylate excels in film formation weather resistance but suffers from “hot stickiness cold brittleness”. Merging polyurethane polyacrylate creates advanced hybrids, while organosilicon enhances properties restricted due hydrolytic crosslinking. In this paper, series of polyurethane–polyacrylate hybrid latexes high content were prepared phase inversion emulsion polymerization technology. Even when the monomer 3-(methacryloyloxy)propyltrimethoxysilane (MPS) was increased 10%, process stable, without gel precipitate. The resulting could remain stable for at least 6 months significant changes their films. effects MPS on thermal latex films systematically researched. study showed that an increase dosage, hardness elastic modulus increased, elongation break absorption decreased, together glass transition temperature surface hydrophilicity. This work aims provide new theoretical guidance preparation silicone-modified latexes, enabling safe production storage.

The development of new encapsulating coatings for flexible solar cells (SCs) can help address the complex problem short lifespan these devices, as well optimize technological process their production. In this study, laminate-type protective composite were prepared using a silicon oxynitride thin-film matrix obtained by curing pre-ceramic polymer perhydropolysilazane (PHPS) through two low-temperature methods: (i) thermal annealing at 180 °C and (ii) exposure to UV radiation wavelengths 185 254 nm. Single-walled carbon nanotubes (SWCNTs) used fillers via dry transfer, facilitating horizontal orientation within matrix. optical, adhesive, structural properties films SiO
