چکیده انگلیسی


- Superhydrophibic coating was prepared by photo-crosslinked PU and F-SiO2.
- PU and F-SiO2 NPs facilitate the superhydrophibic property by synergetic effect.
- The coating possessed hierarchical papillae structure and good biocompatibility.
- It was used for anti-microleakage in dental caries restoration for the first time.
- The coating showed superior anti-microleakage in dental restoration evaluation.

Superhydrophobic coatings were successfully fabricated by photo-crosslinked polyurethane (PU) and organic fluoro group-functionalized SiO2 nanoparticles (F-SiO2 NPs), and were introduced for preventing microleakage in a dental composite restoration. The F-SiO2 NPs possessed low surface energy and the PU can not only improve the mechanical stability but also promote F-SiO2 NPs to form multiscale structure, which could facilitate the properties of the as-prepared superhydrophobic coating by synergetic effect. The morphology and properties of the resulted superhydrophobic coatings with different PU/F-SiO2 ratios were studied using 1H NMR spectrum, fourier transform infrared spectra, scanning electron microscopy, atomic force microscopy and UV-vis spectrophotometry. The results showed that the superhydrophobic coatings with low PU/F-SiO2 ratio (1:3) possessed excellent hierarchical papillae structure with trapped air pockets, high contact angle (160.1°), low sliding angle (< 1°) and good transparency. Additionally, MTT experiments results certified the prominent cell viability and biocompatibility for clinical application. Based on its fantastically superhydrophobic property, the as-prepared superhydrophobic coatings effectively prevented water permeation in resin composite restoration evaluation. This research may provide an effective method to solve the problem of microleakage and will efficiently increase the success rate of dental composite restorations.
