Process and device for particle synthesis on a superamphiphobic or superoleophobic surface

摘要

The present invention relates to a process for particle synthesis on a superamphiphobic or superoleophobic surface comprising at least the followings steps:a) providing a substrate having at least one superamphiphobic or superoleophobic surface, i.e. a surface exhibiting an apparent macroscopic contact angle of at least 140° with respect to 10 µl sized drops of liquids having a surface tension of not more than 0.06 N/m, in particular oils, alkanes, and aromatic compounds;b) providing drops of a liquid material to be solidified on said superamphiphobic or superoleophobic surface;c) maintaining the drops of a liquid material in contact with said at least one superamphiphobic or superoleophobic surface while the solidification of the liquid material to be solidified takes place and particles are formed, wherein the solidification of the liquid material is induced by at least one of the following: evaporation of at least one organic component of the liquid material, one or more phase transitions, cooling, exposure to radiation, e.g. visible light, UV or electron beam, or combining reactants to initiate a chemical reaction, in particular a polymerization reaction.;A second aspect of the invention relates to a device for synthesizing particles comprising a superamphiphobic or superoleophobic surface as defined above.
