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 SiO 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 SiO. 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.
本文通过混合含羟基氟聚合物（PHF）、聚氨酯预聚物（Pre-PU）与环氧功能化 SiO2 纳米粒子，并经热交联，制备出具有抗菌黏附性、优异生物相容性、良好超疏水性和高透光率的涂层。采用傅里叶变换红外光谱（FT-IR）、扫描电子显微镜（SEM）、原子力显微镜（AFM）、紫外-近红外可见光分光光度计（UV-3600）对涂层性能进行了研究。形貌结果表明，通过改变功能化聚合物和 SiO2 的含量，可以控制微纳结构表面的粗糙度尺度。涂层 S2 表现出优异的超疏水性，接触角为 155.9°，滑动角小于 1°，且具有良好的透光性。此外，该涂层表现出抗菌黏附性和良好的生物安全性，有望在口腔领域得到应用。
