The invention provides compositions for forming a hydrophobic or superhydrophobic material, the composition comprising a polyol component having at least two hydroxyl groups per molecule on average; an isocyanate component having at least two isocyanate groups per molecule on average; a single population of nanoparticles having a particle size less than 1 pm; and a solvent; wherein the population of nanoparticles represents at least 5 wt. % of the total of the polyol component, isocyanate component, and population of nanoparticles. The invention also provides hydrophobic or superhydrophobic materials formed from the compositions of the invention, and methods or kits for forming such materials.

(Super) hydrophobic material and coating

The present invention contains a printing apparatus and a method, e.g., for ejecting inks (i.e., pure liquids, mixtures, colloids, etc.) for a very broad range of physical properties (such as viscosity). Acoustic forcesmay be generated by an emitterand a reflectorto detach dropletsfrom a nozzle. The ink may be advanced through the nozzleby a standard back pressure system. A reflectorless chambermay enhance acoustic forcesand the dropletsmay be ejected at a bottomof said chamber, so that dropletsmay be deposited on any substrate
