A composition useful for producing a superomniphobic coating on a substrate, the composition comprising a colloidal suspension of a fluorinated siloxane in a non-silicon-containing fluorinated solvent. In some embodiments, the composition further comprises particles of a hydrophobized metal oxide, e.g., silicon oxide, wherein the hydrophobized metal oxide may be fluorinated. In some embodiments, the composition further comprises a non-silicon-containing fluorinated polymer. The invention is also directed to methods for making the above composition. The invention is also directed to methods for using the above-described composition for rendering a substrate superomniphobic. The aforesaid method comprises depositing a liquid coating solution onto a substrate to form a coated substrate, followed by subjecting the coated substrate to a drying step to remove a liquid phase of the liquid coating solution, wherein the liquid coating solution comprises a colloidal suspension of a fluorinated siloxane in a non-silicon-containing fluorinated solvent.
一种用于在基材上制作超疏磷涂层的组合物,该组合物包括氟化硅氧烷在非含硅氟化溶剂中的胶体悬浮液。在某些实施方案中,组合物进一步包含疏水性金属氧化物(如氧化硅)颗粒,其中疏水性金属氧化物可以是氟化的。在某些实施方案中,组合物进一步包含非含硅氟聚合物。本发明还涉及制造上述组合物的方法。本发明还涉及使用上述组合物使基底具有超疏水性的方法。上述方法包括将液体涂层溶液沉积到基底上以形成涂层基底,然后将涂层基底置于干燥步骤中以除去液体涂层溶液的液相,其中液体涂层溶液包括氟化硅氧烷在非含硅含氟溶剂中的胶体悬浮液。
