简介: |
Ferroelectric nematic liquid crystal (NF LC)
has attracted considerable attention for its unique viscoelastic
nature, topology and electro-optical properties. In this
presentation, we will show diverse chemical structure design
exhibiting NF phase, in both small molecules and
polymers. Meanwhile, these
NF LCs
, as well as other types of novel polar LCs, with
distinct chemical structures largely enrich the toolbox for tuning
the physical properties of ferroelectric nematics, including SHG
coefficient, dielectric permittivity, elasticity, viscosity,
refractive anisotropy, phase transition pathway and temperatures.
Finally, we will introduce our recent progress in the development of
relaxor ferroelectric LC. Through the mixing of traditional
non-polar N LC and emergent polar NF LCs, a new type of
liquid relaxor ferroelectrics is developed with continuous tunning
of the ferroelectric domain size.
Prof. Mingjun Huang received his Bachelor’s Degree from
Peking University in 2010 and PhD degree in Polymer Science at the
University of Akron in 2015. He then moved to MIT Chemistry
department for postdoc research, working on battery electrolyte
material development. He started his independent career in South
China University of Technology from 2019. He is currently a
professor in School of Emergent Soft Matter. He mainly focuses on
the soft matter functional material development within the scope of
optics, electric, and energy storage. His main research projects
involve: 1) Liquid crystals/liquid crystal polymers with
unprecedented structures and properties; 2) Polymer materials for
specific needs in display technology and
energy storage; 3) Self-assembly of macromolecules
with precise chemical structures in condensed states. He has
published more than 100 papers, including the first or corresponding
authored papers in Science, Nat. Chem. and Nat. Phys., etc. He has
also coedited a book and applied more than 20 patents.
