INTRODUCTION Oil-polluted water caused by oil-spill accidents and industrial wastewater leakage usually contains poisonous chemicals, which may threaten human health or bring a disastrous effect on the ecosystem.1−5 Therefore, it is imperative to develop efficient materials and technologies for the separation and removal of oils and organic pollutants from water. Inspired by the special wettability of lotus leaves6,7 and water-strider legs8 in the biological world, superhydrophobic and superoleophilic (SHBOI) materials have drawn considerable attention in the field of oil/water separation.9−13 SHBOI materials are capable of separating oil−water mixtures by selectively absorbing oil and completely repelling water. Recently, numerous researchers have devoted their work to creating SHBOI materials by fabricating the micro/nanosized hierarchical structures with
