Here, we present all dry fabrication of superhydrophobic surfaces through mechanochemical grafting of silicone. The entire process consists of agitating silicone and nanoparticles in a planetary ball mill for a duration on the order of minutes. A lowcost and biocompatible silicone is employed for lowering the surface energy of nanoparticles.

Specifically, a planetary ball mill was used to grind silica nanoparticles and dodecyltrichlorosilane in a milling jar to obtain a superhydrophobic powder within 5 min. The use of ball milling in this application eliminates the need for solvent, which reduces waste and makes the process environmentalfriendly.

Inert Gas Condensation for Nanoparticle Synthesis

Inert Gas Condensation for Nanoparticle Synthesis

As a class of bottomup viewpoint in nanoparticle synthesis, inert gas condensation is a perfectly developed and popular nanoparticle synthesis technique owing to its capability and flexibility to control the synthesis process. Briefly, the material is evaporated under the pure helium atmosphere with the helium atoms serving as a cooling agent condensing the atoms to finalize the formation of ...
