摘要:
  Water is essential for life on earth and considered a symbol of purity. 71% of the surface of our planet is covered by water, and our own body is composed of 65% of this simple but vital molecule. Considering increasing environmental issues, the idea of replacing plastics with water-based materials, so-called hydrogels, seems quite reasonable. Inspired by the self-cleaning fish scales and articular cartilage, we fabricated a series of functional hydrogels through the design of 2D surfaces and 3D networks. For example, we developed underwater superoleophobic hydrogels and extended this concept to design antibiofouling coatings. Furthermore, we developed a highly anisotropic hydrogel having a large compression resistivity and, in its orthogonal direction, an ultralow internal friction, so that this material, just like articular cartilage, efficiently insulates horizontal vibrations even under a heavy weight. We anticipate that these bio-inspired design strategies will open up new possibilities for developing soft materials with unusual functions.
