Highly reliable transparent superhydrophobic composite by organosilane/denture base resin-modified alkylated silica nanoparticles against contaminants

A problem associated with long-term service of dentures is their instability in the oral environment, especially their poor antifouling properties. Therefore, it is highly desirable to introduce an effective protective layer compatible with polymer dentures for the reliable use of dentures. We developed a denture-based transparent superhydrophobic film (DTSF) by integrated synergistic self-assembly between a double bond-silicon oligomer and green hydrophobic nanoparticles. The superhydrophobic protective layer (with a high water contact angle of >164. and an ultralow sliding angle of <1.) was deposited onto the denture, resulting in excellent transparency, water-repelling, and self-cleaning properties. Additionally, the DTSF surface could preserve superhydrophobicity after being threatened by mechanical action, chemical corrosion, and water-based contaminants. Furthermore, the protected denture exhibited a more reliable antifouling ability, even when exposed to acids, alkali, sweets and spicy solvents. This study provides a practical solution for improving the reliability and value of dentures in the oral environment.

Automated summary

Dentures often face problems of instability and poor antifouling properties in the oral environment. In this study, a denture-based transparent superhydrophobic film (DTSF) was developed by self-assembly, providing excellent transparency, water-repelling, and self-cleaning properties. The protected denture showed reliable antifouling ability even when exposed to various substances, making it a practical solution for improving denture reliability and value.
