Abstract:
In this paper, coatings with antibacterial adhesion, excellent biocompatibility, good superhydrophobicity and highly transmittance were fabricated by mixing hydroxyl group fluropolymer (PHF), polyurethane oligomer (Pre-PU) with epoxy functionalized SiO2 nanoparticles and thermal-crosslinked. The properties of coatings were investigated by Fourier transform infrared spectroscopy (FT-IR), Scanning electron microscopy (SEM), Atomic force microscopy (AFM), Ultraviolet near-infrared visible spectrophotometer (UV-3600). The morphology results indicated that the roughness scale of micro-nano structure surface can be monitored by changing the contents of functionalized polymers and SiO2. The coating S2 showed outstanding superhydrophobicity with the contact angle of 155.9°, the sliding angle less than 1°, and good transparency. Furthermore, the coating exhibited antibacterial adhesion and favorable biosafety, confirming a potential for application in the oral field.

Cleaning, Sterilization, and Disinfection
Cleaning
The cleaning process usually involves using water with detergents or enzymatic cleaner and removing foreign material from objects and surfaces, including organic material such as body fluids or inorganic material like soil. Cleaning is performed before high-level disinfection and sterilization because foreign materials on the cover of the devices interfere with process...

Coat Assembly and GTPases
Coat assembly depends on the local availability of phosphatidylinositol phosphates or PIPs and GTP-binding proteins. Adaptor proteins, which link the coat proteins to the membrane, bind to these PIPs and play a crucial role in controlling...
