Topic: Bioinspired Multi-Scale Pore/Channel Systems

Learning from nature is the eternal theme of the development of new materials and systems. The relationship between the micro-/nano structures of biological tissue and their performances provides inspirations for proposing new ideas for the additive and subtractive manufacturing of functional materials. For microscale system, inspired by the dynamic and non-fouling fluid transport through some biological pores, which are composed of liquid infused porous structures, we proposed the concept of liquid gating technology. These liquid gating membranes utilize the capillary-stabilized functional liquid as a pressure-driven, reversible, and reconfigurable gate to fill and seal the pores in the closed state and create completely liquid-lined pores in the open state under pressure changes. In recent years, this concept has become a reality through the development of various smart liquid gating membrane materials by designing the two essential part of the liquid gating membranes: the solid porous matrix and the gating liquid. For nanoscale system, inspired by the ion channels, we designed and prepared many bioinspired smart symmetric/asymmetric nanochannels by physicochemical design of responsive porous materials, and realized the regulation of mass transport in the nanoconfined spaces, and focus the new research directions on bioinspired nanofluidic iontronics.
