Superhydrophobic coatings with self-cleaning and antibacterial adhesion properties for denture base.
Journal of the Mechanical Behavior of Biomedical Materials(2019)
摘要
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.
