Nature has developed materials, objects, and processes which
function from the macroscale to the nanoscale. These have
gone through evolution over 3.8 billion years. The emerging
field of biomimetics allows one to mimic biology or nature to
develop nanomaterials, nanodevices, and processes.
Properties of biological materials and surfaces result from a
complex interplay between surface morphology and physical
and chemical properties. Hierarchical structures with
dimensions of features ranging from macroscale to the
nanoscale are extremely common in nature to provide
properties of interest. Molecular scale devices,
superhydrophobicity, self-cleaning/anti-fouling, drag reduction
in fluid flow, energy conversion and conservation, high
adhesion, reversible adhesion, aerodynamic lift, materials and
fibers with high mechanical strength, biological self-assembly,
anti-reflection, structural coloration, thermal insulation, self-
healing, and sensory aid mechanisms are some of the
examples found in nature which are of commercial interest.
This talk will provide a broad overview of four selected objects
of interest found in nature and applications under development
or available in the marketplace. These will include Lotus Effect
used to develop superhydrophobic and self-cleaning/anti-
fouling surfaces with low adhesion, Rose Petal Effect used to
develop superhydrophobic surfaces with high adhesion, Gecko
Adhesion to develop surfaces with reversible adhesion, and
Shark Skin to develop surfaces with low fluid drag and anti-
fouling characteristics.
