Superhydrophobic materials have triggered large interest due to their widespread applications, such as self-cleaning, corrosion resistance, anti-icing, and oil/water separation. However, suffering from weak mechanical strength, plenty of superhydrophobic materials are limited in practical application. Herein, we prepared hierarchical carbon microflowers (CMF) dispersed with molybdenum trioxide (MoO) nanoparticles (MoO/CMF) via a two-step preparation method. Taking advantage of high-adhesion epoxy resin and the modification with 1H,1H,2H,2H-perfluorodecyltriethoxysilane (PDES), the modified MoO/CMF (PDES-MoO/CMF) coating on various substrates shows great waterproof ability, excellent chemical stability, good mechanical durability, and self-cleaning property. More significantly, the prepared PDES-MoO/CMF powder with high thermal stability (250°C) can be used for oil/water separation due to its special flower-like structure and superhydrophobicity/superoleophilicity. All of these advantages endow the superhydrophobic powders with huge potential in the practical applications.
超疏水材料由于其广泛的应用，如自清洁、耐腐蚀、抗结冰和油水分离等，引起了人们的极大兴趣。然而，由于机械强度较弱，许多超疏水材料在实际应用中受到限制。本文通过两步法制备了分层碳微花（CMF）分散的三氧化钼（MoO）纳米粒子（MoO/CMF）。利用高附着力的环氧树脂和 1H，1H，2H，2H-全氟癸基三乙氧基硅烷（PDES）的改性，各种基底上的改性 MoO/CMF（PDES-MoO/CMF）涂层具有出色的防水能力、优异的化学稳定性、良好的机械耐久性和自清洁性能。更重要的是，由于其特殊的花状结构和超疏水/超亲油性，所制备的具有高热稳定性（250°C）的 PDES-MoO/CMF 粉末可用于油水分离。这些优点使超疏水粉末在实际应用中具有巨大的潜力。
