    • Coated particles comprise a core of fumed or precipitated inorganic metal oxide having a surface area of about 50 to about 500 square meters per gram and a shell consisting of an array of fluoroalkyl molecular chains at a density of at least 1 chain per square nanometer, joined to the core by covalent chemical bonds and with a total organic content of at least 9.9 percent by weight. These particles are formed by the chemical attachment of fluoroalkyl-alkylsilanes after exposure to an alkylamine and followed by an extraction to remove any organic material not covalently bound. The dense packing of molecular chains in the fluoroalkyl shell combined with a mesoporous structure imparts a very low surface energy, a very high specific surface area, and surface texture over a wide range of length scales. Such features are highly desirable for the creation of, for example, superhydrophobic and superoleophobic surfaces, separation media, and release films.
    • 涂覆的颗粒包括表面积为约50至约500平方米/克的热解或沉淀的无机金属氧化物的核心和由至少1个链每平方毫米的密度的氟代烷基分子链阵列组成的壳, 通过共价化学键到达核心,总有机含量为至少9.9重量%。 这些颗粒是在暴露于烷基胺之后通过氟代烷基 - 烷基硅烷的化学连接形成的,然后进行萃取以去除未共价结合的任何有机材料。 结合中孔结构的氟烷基壳中的分子链的密集填料在宽范围的长度尺度上赋予非常低的表面能,非常高的比表面积和表面纹理。 这种特征对于产生例如超疏水和超疏油表面,分离介质和脱模膜是非常需要的。
