用于管状结构的内表面的超疏水组合物和涂布方法
摘要：
一种用于沉积涂层的方法包括在管状结构的内部体积内产生真空，其中所述管状结构也包括内表面。将气体供给至所述管状结构的内部体积，其中所述气体包括气相中的等离子体前体。所述管状结构相对于接地偏压。形成具有密度并沿着所述管状结构的长度周期性设置的等离子体。产生等离子体前体气体的正离子，所述正离子沉积于所述内表面上，从而在所述内表面上形成涂层，其中所述涂层显示出大于120°的水接触角。
摘要（英）：

A method for depositing a coating includes creating a vacuum within an interior volume of a tubular structure, wherein the tubular structure also includes an internal surface. Gas is supplied to the interior volume of the tubular structure, wherein the gas includes a plasma precursor in the gas phase. The tubular structure is biased relative to ground. Plasma having a density is formed and cyclically positioned along the length of the tubular structure. Positive ions of the plasma precursor gas are generated and are deposited on the internal surface forming a coating on the internal surface, wherein the coating exhibits a water contact angle of greater than 120°.
