摘要： A coating composition comprising hydrophobic particles having an average size of between 7 nm and 4,000 nm and a wetting agent for promoting dispersion of the hydrophobic particles in water. The hydrophobic particles may be oxides, such as silica, titania, or zinc oxide. In one embodiment, the hydrophobic particles comprise fumed silica. The coating composition may be brushed, spin coated, or dipped onto a surface. In one embodiment, once the coating composition dries, the coating formed thereby is characterized by a contact angle formed with a water droplet in excess of 165 degrees. A method of making a coating composition comprising providing hydrophobic particles having an average size of between 7 nm and 4,000 nm, mixing a wetting agent with the hydrophobic particles to form a paste, and dispersing the paste in water by mixing to form a mixture.

摘要： A super hydrophobic self-cleaning coating composition composed of from 0.001 to 5% by weight of hydrophobic fumed silicas coated in 95% to 99.999% by weight of a solvent, preferably acetone, to form a super hydrophobic coating for forming an almost clear, translucent dirt repellant film on a painted material, plastic, metal, glass, ceramic, fiberglass, wood, waxed or polymer substrate. The treated fumed silica in a solvent forms a film having a contact angle of at least 165 degrees as compared to water having a contact angle of from 50 to 60 degrees on a noncoated surface. The composition imparts a degree of hydrophobicity to the surface so that the surface has a tilt angle of sliding of less than 2 degrees as compared to water on a noncoated surface having a tilt angle of sliding of 90 degrees or higher.

摘要： A hydrophobic self cleaning coating composition that can be applied by conventional methods such as by spraying the composition onto a surface forming creating a wet and dry dirt repellent coating on the surface. The coating utilizes hydrophobic nanoparticles of fumed silica and/or titania in a solvent which evaporates at ambient temperature. The coating solves the problem of poor resistance to UV light, opaque appearance, and/or abrasion found in previous coatings of similar nature. Virtually transparent coating are produced as compared to conventional coatings of comparable hydrophobicity which are typically white or opaque. The coating can be applied by a single and easy spraying method and the super hydrophobic property can be achieved by drying the film by evaporation of the solvent at ambient temperature for 5 to 10 minutes. Embodiments of the hydrophobic self-cleaning coating composition can be produced resulting in a clear coating or in some cases a translucent dirt repellant film or coating on painted material, plastic, metal, glass, ceramic, fiberglass or a polymer substrate. One preferred coating composition utilizing an effective amount of a treated fumed silica in a solvent forms a coated surface providing a contact angle of at least 165 degrees as compared to water having a contact angle of from 10 to 15 degrees on a noncoated surface. The self-cleaning coating composition imparts a degree of hydrophobicity to a surface so that the treated surface will have a tilt angle of sliding of less than 2 degrees as compared to water on a noncoated surface having a tilt angle of sliding of 90 degrees or higher.
摘要翻译：疏水性自清洁涂料组合物，其可以通过常规方法施用，例如通过将组合物喷涂到表面上形成湿表面和干污垢涂层的表面上。该涂层使用在环境温度下蒸发的溶剂中的热解法二氧化硅和/或二氧化钛的疏水性纳米颗粒。该涂层解决了在类似性质的先前涂层中发现的耐紫外线性差，不透明外观和/或耐磨性差的问题。与通常为白色或不透明的相当的疏水性的常规涂层相比，产生几乎透明的涂层。可以通过单一且容易的喷涂方法施加涂层，并且可以通过在环境温度下蒸发溶剂5至10分钟来干燥膜来实现超疏水性。可以制造疏水性自清洁涂料组合物的实施方案，从而形成透明涂层，或在某些情况下产生在涂漆材料，塑料，金属，玻璃，陶瓷，玻璃纤维或聚合物基材上的半透明防污膜或涂层。使用有效量的经处理的热解法二氧化硅在溶剂中的一种优选的涂料组合物与在非涂层表面上的接触角为10至15度的水相比形成了涂覆表面，其提供至少165度的接触角。自清洁涂料组合物赋予表面一定程度的疏水性，使得与具有90度或更高的滑动倾斜角的未涂覆表面上的水相比，经处理的表面将具有小于2度的倾斜倾斜角度。

Preferred photoresist compositions of the invention contain an Si-polymer such as a silsesquioxane that has sulfonamide substitution and may be employed in multilayer resist systems. In preferred aspects, the Si-polymer has both sulfonamide substitution as well as moieties that can provide contrast upon exposure to photogenerated acid.
