General description

Vinyltrimethoxysilane (VTMS) is a silane coupling agent with a silicon and hydroxyl groups that can be used to enhance the wettability and improve the superhydrophobic characteristics of different composites.

Application

VTMS may be used to provide superhydrophobicity to different materials like TiO2, talc, kaolin, magnesium oxide nanoparticles, ammonium phosphate and PEDOT. It modifies the surface by capping the material and creates a protective layer that is water resistant and can be used in major coating industries.

Plastic bottles are generally recycled by remolding them into numerous products. In this study, waste from plastic bottles was used to fabricate recycled polyethylene terephthalate (r-PET) nanofibers via the electrospinning technique, and high-performance conductive polyethylene terephthalate nanofibers (r-PET nanofibers) were
