- This paper follows on the ground breaking idea we developed here at Bradford that gas viscosity controls the maximum coating speed at which a liquid-gas free surface wet a solid substrate. This paper tests this concept in slot coating, key method for fabricating submicron thin films. We show in unique experiments that by coating in rarefied helium rather than atmospheric air we can coat faster thus reduce further film thickness. No such fundamental proposition has ever been conceived. This research paves the way for radical innovation in the coating industry. Now the subject of new modelling of wetting (PhysRevLett.118.114502).
