The present teachings generally provide curable polysiloxane compositions including a base resin and a lubricating liquid. The curable polysiloxane compositions can create a slippery material or coating, where an overlayer of the lubricating liquid is spontaneously presented at an exposed surface of the cured base resin. Articles of manufacture including the curable polysiloxane compositions and slippery coatings and materials also are provided. Per some aspects of the invention addition and condensation based curable silicone coating composition is provided which may be used to to provide slippery, lubricious, or repellent materials and coatings against a fluid matter including water, oil, viscous fluids, slurries, complex fluid mixtures with or without solids in them, biological fluids and organisms, bodily fluids, ice, frost, and mixtures thereof; to reduce drag or friction; to enhance product performance by providing slippery feeling, by providing anti-fouling function, by providing application mechanism of payloads such as lubricants, personal care products, drug molecules, and biocides; to provide non-stick or easy-to-clean function; to provide anti-fouling or foul-release function on open surfaces, internal surfaces, membranes; to provide pinning free or low contact angle hysteresis surfaces; to provide homogeneous interface to suppress nucleation; to provide a barrier layer such as anti-corrosion; to provide anti-stain, anti-smudge, anti-fingerprint, anti-soil function. The curable silicone coating composition of the present invention comprises a stable thin liquid overlayer (LOL) leading to a slippery surface with very low roll-off angle for water typically seen as equal or greater than 15 degrees when a 15 uL water droplet is applied on said slippery surfaces. In addition, the curable polysiloxane compositons can further incorporate at least one or more surface active amphiphilic polymers leading to a self-lubricating amphiphilic slippery coating, and can incorporate optional biocides and/or biocidal effect boosters that can further impart anti-biofouling functions in both static and dynamic conditions.
本教导一般提供可固化的聚硅氧烷组合物,包括基底树脂和润滑液体。可固化的聚硅氧烷组合物可以制成滑爽的材料或涂层,其中润滑液体的覆盖层会自发地呈现在固化的基础树脂的暴露表面。本发明还提供了包括可固化聚硅氧烷组合物和滑爽涂层及材料的制造物品。根据本发明的某些方面,本发明提供了基于添加和缩合的可固化有机硅涂料组合物,可用于提供防滑、润滑或排斥流体物质的材料和涂料,这些流体物质包括水、油、粘性流体、泥浆、含有或不含固体的复杂流体混合物、生物流体和有机体、体液、冰、霜及其混合物;以减少阻力或摩擦;通过提供滑爽感、防污功能、提供有效载荷(如润滑剂、个人护理产品、药物分子和杀菌剂)的应用机制来提高产品性能;提供不粘性或易清洁功能;在开放表面、内表面、膜上提供防污或除污功能;提供无针刺或低接触角滞后表面;提供均匀界面以抑制成核;提供阻挡层,如防腐蚀;提供防污、防污迹、防指纹、防污功能。本发明的可固化有机硅涂料组合物包括一个稳定的薄液体覆盖层(LOL),可形成滑爽的表面,当 15 uL 的水滴在所述滑爽表面上时,水的滚落角非常低,通常等于或大于 15 度。此外,可固化的聚硅氧烷复合物还可进一步加入至少一种或多种表面活性两性聚合物,形成自润滑的两性滑爽涂层,并可加入任选的杀菌剂和/或杀菌效果增强剂,进一步增强静态和动态条件下的防生物污染功能。
