摘要

Multi-walled carbon nanotubes (MWCNTs) were facilely decorated with tannic acid (TA) and the MWCNTs/TA dispersion was vacuum-filtered to fabricate carbonaceous coatings with superoleophobicity and ultra-low oil adhesion underwater (OCA = 164.8 degrees, SA = 2.7 degrees). The super-oil-repellent property can be well maintained for long-term use, even in strong acidic, alkaline or saline environments.
