Methodology for Robust Superhydrophobic Fabrics and Sponges from In Situ Growth of Transition Metal/Metal Oxide Nanocrystals with Thiol Modification and Their Applications in Oil/Water Separation

摘要: Solid surfaces possessing both superhydrophobic and superoleophilic properties have attracted significant interest in fundamental investigations potential applications the fields of self-cleaning surfaces, oil/water separation, microfluidic channels. In this paper, a general methodology for robust fabrics sponges was proposed via situ growth transition-metal oxides metallic nanocrystals, including simple neutralization reaction oxidation–reduction reaction. The porous coated with Group VIII IB nanocrystals (such as Fe, Co, Ni, Cu, Ag) can not only present multiscale surface roughness, but also readily coordinate thiols, leading to special wettability. our previous work, it has been confirmed that interaction between thiols plays role introduction hydrophobic ingredients. demonstrated efficient control nucleation V...
