Ultra-high hydrophobicity on the surface of nanocomposite hydrogels with a poly(n-isopropylacrylamide) / clay network
关键字：Surface property, Nanocomposite, Hydrogel, PNIPA, Clay
Surface wettability is one of the most important properties of all materials, since it reflects the real structure and chemical composition at the outer-most surface, and is a decisive factor in many properties. As readily ex...
