Durable superamphiphobic wood surfaces from Cu2O film modified with fluorinated alkyl silane
Abstract
A simple hydrothermal process with further hydrophobization was developed for fabricating durable superamphiphobic films of cuprous oxide (Cu2O) microspheres on a wood substrate. With the advantages of simple operation, low cost, short reaction time, and environmental friendliness, the present method can be well adapted to fabricate Cu2O microstructures on wood surfaces. Meanwhile, the wood coated with a hydrolysis product from long chain fluoroalkyl silane of (heptadecafluoro-1,1,2,2-tetradecyl)trimethoxysilane has a durable superhydrophobic and superoleophobic surface and the coating shows excellent durability to acid, high temperature and humidity, and abrasion. The coatings effectively protect the substrate from damages, expanding the wood application fields. The functional coating may have a broad prospect of applications from the bridges and buildings to automobiles and other possible aspects.
