A superamphiphobic coating on a wood shows extreme liquid repellence against water, ethylene glycol, diiodomethane and olive oil.
- •
The coated wood sample can have the required geometrical homogeneity to establish superamphiphobic properties.
- •
To our knowledge, this is the first time superamphiphobicity based on overhang structures has been shown for a renewable bio-based material.A superamphiphobic coating on a wood shows extreme liquid repellence with static contact angles (CA) greater than 150° and roll-off angles less than 10° against water, ethylene glycol, diiodomethane and olive oil.
