Abstract:
Biological surfaces provide endless inspiration for design and fabrication of smart materials. It has recently been revealed to have become a hot research area in materials and science world. Inspired by the roles of micro- and nanostructures in the water collecting ability of spider silk, a series of bioinspired gradient fibers has been designed by integrating fabrication methods and technologies such as fluid-coating, electrospinning-electrospraying, and webassembly, etc., where the “spindle-knot/joint” structures with multiple gradients (e.g., roughness, curvature, etc.) can be realized to achieve functions of droplet transport, fog-harvesting, etc. In addition, the integrative conical spine materials with gradient micro- and nanostructures can be fabricated to achieve the ability of droplet transport in efficiency. Otherwise, the functional surfaces with microand nanostructures are developed to achieve the effect of water repellency by methods combining machining, electrospinning, soft lithography, and nanotechnology. These micro- and nanostructure surfaces with wettability exhibit robust transport and controlling of microdroplets, which would be promising applications.
Biography:
Yongmei Zheng completed her PhD and currently working as a professor at Beihang University. His research interests are focused on bioinspired surfaces with gradient micro- and nanostructures to control dynamic wettability and develop the surfaces with characteristics of water repellency or fog-harvesting, tiny droplet transport, and so on. She has publications more than 100 SCI papers included in Nature, Adv. Mater., etc., with 12 cover stories and a book “bioinspired wettability surfaces: Development in micro- and nanostructures”. Her work was highlight as scientist on News of Royal Society of Chemistry, Chemistry World in 2014. She is a member of Chinese Composite Materials Society (CSCM), International Society of Bionic Engineering (ISBE). She wins an ISBE outstanding contribution award in 2016 by ISBE.
