A Superamphiphobic Macroporous Silicone Monolith with Marshmallow-like Flexibility

A monolithic material has marshmallow‐like flexibility and superamphiphobic properties on any cutting surface. The two‐step synthesis consists of a simple sol–gel process to obtain vinyl‐modified superhydrophobic monolithic gels and grafting of perfluoroalkyl groups onto the pore surface to decrease...

Description
Summary:A monolithic material has marshmallow‐like flexibility and superamphiphobic properties on any cutting surface. The two‐step synthesis consists of a simple sol–gel process to obtain vinyl‐modified superhydrophobic monolithic gels and grafting of perfluoroalkyl groups onto the pore surface to decrease surface energy. These superamphiphobic materials float on water and even on organic liquids with low polarity, such as alkanes.
