摘要：
Directional wetting on limited sectors of surfaces is achieved on partially wetting microstructured surfaces by placing non-symmetrical microstructures in a regular rectangular lattice. Droplet spreading to a 90 degrees sector is possible when the microstructures are designed to present broad features towards the right and top and sharp features towards the left and bottom (see image).
