Omniphobic fluorogel elastomers were prepared by photocuring perfluorinated acrylates and a perfluoropolyether crosslinker. By tuning either the chemical composition or the temperature that control the crystallinity of the resulting polymer chains, a broad range of optical and mechanical properties of the fluorogel can be achieved. After infusing with fluorinated lubricants, the fluorogels showed excellent resistance to wetting by various liquids and anti‐biofouling behavior, while maintaining cytocompatiblity. 相似文献

Using the tip of a scanning tunnelling microscope a metal‐free phthalocyanine has been transformed into a silver‐phthalocyanine on a surface. The individual reactions have been performed atom by atom. Each product has been imaged with the scanning tunnelling microscope. Along with the transformation of the molecule, controlled tautomerization and H hopping have been induced by injection of electrons and demonstrate the precision a state‐of‐the‐art scanning tunnelling microscope has reached. 相似文献
