![]() Crack-free films can be produced at thicknesses much greater than the critical cracking thickness for a suspension without capillary interactions, and even persists after sintering. This secondary liquid preserves the particle cohesion, modifying the structure and increasing the drying rate. We present a novel, generic approach to suppress crack formation in thin films made from hard particle suspensions, which are otherwise highly susceptible to cracking, using the capillary force between particles present when a trace amount of an immiscible liquid is added to a suspension. ![]() ![]() ![]() Cracks, formed during the drying of particulate films, can reduce the effectiveness or even render products useless. ![]()
