Bioinspired micro/nanostructured surfaces with wettability from design to functions
Yongmei Zheng
Beihang University, China
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 web-
assembly, 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 micro-
and 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.
Speaker 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.
