Abstract:
1. A method to form a coating with surface features on a substrate comprising the steps of: (a) providing a first liquid composition including at least a volatile component and at least a non-volatile component; (b) providing at least an atomizing device having a first conduit for flowing said first liquid composition from a first liquid inlet to a first orifice and a second conduit for flowing a first gas stream from a second inlet to a second orifice; (c) atomizing the liquid composition exiting the first orifice by the first gas stream which exceeds sonic speed while providing a second gas stream and flowing it from an additional conduit to a third orifice and directing said second gas stream so that it interacts with the first gas stream during atomization, and thereby increasing the temperature of at least a part of the first gas stream to a temperature higher than ambient temperature so that particles are formed from the non-volatile component of the liquid composition; (d) depositing the particles to form a coating with three-dimensional surface features on the substrate.
