| abstract |
The present invention relates to an apparatus comprising a liquid-impregnated surface (100), wherein the surface (100) comprises a matrix of impregnating liquids and solid features (102) And which is sufficiently close to be contained in them stably, and a method for the same. In some embodiments, the apparatus has one or both of the following: (i) 0 <?? 0.25, where? Is the projection of the liquid-impregnated surface 100 corresponding to a non-immersed solid at equilibrium The scale fraction of surface area]; And (ii) S ow (a) <0, where S ow (a) is the spreading coefficient defined as γ wa - γ wo - γ oa where γ is the number of the two Where w is water, a is air, and o is the impregnation liquid. |
