  • Bioinspired Smart Materials for Directional Liquid Transport
    Industrial & Engineering Chemistry Research, 2017
    Co-Authors: Ying Cui, Hao Bai
    Abstract:

    Bioinspired materials capable of driving Liquid in a directional manner have wide potential applications in many chemical engineering processes, such as heat transfer, separation, microfluidics, and so on. Numerous natural materials and systems such as spider silk, cactus, shorebirds, desert beetles, butterfly wing, and Nepenthes alata have been serving as a rich source of inspirations in the area. During the last decades, great efforts have been devoted to design bioinspired smart materials for directional Liquid Transport. In this review, we begin by introducing several natural materials and systems with surface structural features contributing for their directional Liquid Transport Property, followed by the basic concepts and theories about surface wettability, droplet motion, and driving forces with different structural features. Then, we summarize some typical applications of such bioinspired smart materials in industrial processes and chemical engineering, particularly in heat transfer, separation, ...

  • Bioinspired fabrication of asymmetric wood materials for directional Liquid manipulation and Transport
    Chemical Engineering Journal, 2020
    Co-Authors: Yu-qiong Luo, Fei Song, Xiu-li Wang, Yu-zhong Wang
    Abstract:

    Abstract Directional Liquid Transport, an essential process found in many natural creatures, is of great importance to environment, energy, and even life. Wood plants possess directional water Transportation from soil to air, however, wood-based materials have no longer such performance because the pressure difference induced by transpiration is lost. Inspired by the controlled Transport of water droplets on cactus pine, here, wettability gradient is constructed along wood channels, fabricating novel asymmetric wood slices. The hierarchically micro-/nano-structures and wettability gradients of the slices guarantee the tunable surface wettability and directional Liquid Transport Property. Besides water, the resultant asymmetric wood can directionally deliver oils and moisture. Moreover, the functional wood displays high resistance against harsh corrosions without changing micro-structures or losing directional Liquid Transport Property. The results demonstrate the asymmetric wood material will be useful in Liquid manipulation, water harvest and treatment, self-cleaning, anti-fouling, and smart building materials.

  • Effect of asymmetric wettability in nanofiber membrane by electrospinning technique on separation of oil/water emulsion.
    Chemosphere, 2018
    Co-Authors: Jiyeol Bae, Hayoung Kim, Kwang Soo Kim, Heechul Choi
    Abstract:

    Abstract Oil/water separation is an important issue in the environmental field because of increasing worldwide oil pollution. In particular, emulsion under 20 μm in size causes a serious problem in water treatment. Thus, development of an effective oil/water emulsion separation membrane is required. Asymmetric wettability is one effective technique for emulsion separation due to its directional Liquid Transport Property. In this research, wettability was controlled by adjusting the diameter of an electrospun nanofiber for a difference in surface roughness. Through analysis of the surface structure and contact angle of nanofibers with various diameters, the contact angles of fibers with different diameters were increased about 40° to confirm that surface structure affects surface wettability. Comparison of asymmetric wettability membranes (AwENMs) and a single membrane (ENM) for oil/water emulsion separation shows that AwENMs perform about two times faster and reject 10% of emulsion.
