Self-cleaning superhydrophobic surfaces are a highly sought-after class of materials which have the potential to be hugely beneficial to many commercial industries. A prospective application is within the paints and coatings industry. However, photo-degradation of titanium dioxide-based (TiO₂) coatings often limits the practical implementation of applied superhydrophobic coatings. Here, we present a facile process for fabricating pigmented superhydrophobic nanomaterials which display excellent UV durability, owed to the synergistic effect of using cerium oxide (CeO₂) nanoparticles and a silicone elastomer, polydimethylsiloxane (PDMS). Composite coatings resisted photo-degradation after 250 hours of intense UV irradiation (over 100 days under ambient conditions) and continued to exhibit promising self-cleaning properties.

通过限制光催化活性及其效果，具有增强的紫外线回弹性的色素自清洁涂料

自清洁超疏水表面是一类备受追捧的材料，对许多商业行业都有巨大的潜力。预期的应用是在油漆和涂料工业中。然而，基于二氧化钛的（TiO ₂）涂层的光降解常常限制了所施加的超疏水涂层的实际实施。在这里，由于使用氧化铈（CeO _2）的协同作用，我们展示了一种制造具有超强紫外线耐久性的着色超疏水纳米材料的简便方法。）纳米颗粒和有机硅弹性体聚二甲基硅氧烷（PDMS）。复合涂料在经过250小时的强紫外线照射后（在环境条件下超过100天）可以抵抗光降解，并继续展现出令人期待的自清洁性能。
