Abstract
Abstract In this study, we reported the first example of multi-functional 1-triacontanol-polymerized-octadecylsiloxane (1-triacontanol-PODS) coatings. The multi-functional 1-triacontanol-PODS coatings are formed on various substrates including cotton wool, filter paper, sponge, and glass via immersing the substrates in hot solutions (∼50 °C) of 1-triacontanol, octadecyltrichlorosilane (OTS) and ethanol. After coating, it is found that the 1-triacontanol-PODS-coated materials possess with superhydrophobicity, superoleophilicity and anti-corrosion ability. Furthermore, highly efficient oil/water separation and excellent self-cleaning ability were also observed on the 1-triacontanol-PODS-coated materials. For instance, the flux of 1-triacontanol-PODS coating modified cotton wool for ClCH 2 CH 2 Cl/H 2 O separation was ranged from 5677 to 32,157 L m −2 h −1 after 50 cycles, and the mass-based absorption capacities for the oils are in the range 15–31; Both micro (>20 μm) and nano dust particles (∼50 nm) were fully removed from 1-triacontanol-PODS coating-modified glass substrate.
