Abstract

Superhydrophobic polyurethanes offer robust hydrophobicity and corrosion resistance. However, it is essential to consider the durability and environmental constraints associated with these materials. This study prepared a bio-based superhydrophobic polyurethane coating film using epoxidized soybean oil, superhydrophobically modified silica nanoparticles, and OH-PDMS-OH as surface modifiers. The coating film exhibited sustained super-hydrophobicity and an excellent antifouling effect for pu-erh tea and edible oils, among other substances, after 14 days of immersion in solutions with different pH values, 28 days of exposure to air, and 2000 abrasion cycles. This finding can be applied to the development of daily indoor and outdoor antifouling protective coatings and provides a new method for the preparation of green and durable superhydrophobic antifouling coating films.

摘要

超疏水聚氨酯具有强大的疏水性和耐腐蚀性。然而，考虑这些材料相关的耐久性和环境限制至关重要。本研究使用环氧化大豆油、超疏水改性二氧化硅纳米颗粒和OH-PDMS-OH作为表面改性剂制备了一种生物基超疏水聚氨酯涂膜。在不同pH值的溶液中浸泡14天、暴露于空气中28天以及经过2000次磨损循环后，该涂膜对普洱茶、食用油等物质表现出持续的超疏水性和优异的防污效果。这一发现可应用于日常室内和室外防污保护涂料的开发，并为制备绿色耐用的超疏水防污涂膜提供了一种新方法。
