In numerous biological systems, particularly in plants, liquid is transported via surface-tension-driven flow through porous structures, reaching several meters in transport length without the need for external mechanical pumps. This cellular fluidic behaviour has attracted attention over the past decade, due to potential application in fields such as tissue engineering, microfluidics, membranes and energy conversion [1,2]. All of these applications require a certain degree of adaptability such as variable shape, porosity and material composition. To meet these requirements, in this work, ceramic microporous guides are printed by using a combination of an additive manufacturing process, direct writing, with colloidal assembly and later functionalised by Atomic Layer Deposition (ALD). Previous work by our group has demonstrated that this printing method, referred to as AMCA (Additive Manufacturing combined with Colloidal Assembly), enables fast printing of water-based additive-free suspensions in various patterns including lines, areas and curves onto a variety of substrates including curved surfaces [3,4,5]. For this work, the printed structures are then calcinated after ALD coating of titania and alumina to achieve the desired isoporous ceramic-based material. Our results show the potential of such isoporous ceramic guides for spontaneous imbibition due to surface-tension-driven flow, where the flow is directly impacted by the (iso)porosity size and the material hydrophilicity (alumina vs. titania). The adaptability of this method to create tailored guides makes it a promising process for the fabrication of lab-on-a-chip devices [2,6].
