Our project within the collaborative research center „Interaction between transport and wetting processes“ examines the transport of charged molecules in solution through nanometer scale pores with varying wettability. We demonstrated how gradually increasing contact angle of nanopores affects ion transport as well as fluid condensation. Upon understanding the influence of wettability on fluid and moleculear transport, we achieved gating of fluid imbibition and drop coalescence. We are furthermore interested in the effects of wettability gradients in nanopores on fluid and molecular transport.
