- Complete wetting surface is a surface providing spontaneous transportation of water. With well-organized structure acting as a way, spontaneous transportation of water to a desired direction is made without any energy requirement. However, high surface energy of complete wetting surface limits its potential to commercial applications by easily recovering to a hydrophobic state. Here, we introduce nanostructure superhydrophilic surface of DLC (diamond-like carbon) containing silicon oxide as a long-lasting surface. We deposited Si-DLC by RF-CVD (radio frequency – chemical vapor deposition) method with a mixture of benzene and silane gases. And hydrophilic Si-O group and nanomorphology are made on the surface during following oxygen plasma treatment. We found the relation between long-lasting behavior and chemical & morphological properties of Si-DLC film from the aging experiments up to 20 days in the air and water immersion. And we have further applied the long-lasting hydrophilic surface on fiber network of a non-woven fabric.
