We are excited to announce that Professor Vladimir G. Chigrinov, from the Hong Kong University of Science and Technology, will be delivering a Keynote Virtual Presentation at the International Congress on Materials Science and Nanotechnology, taking place November 20-22, 2025, in Singapore and Online.
Keynote Title:
Azodye nanolayers: New trend in liquid crystal devices
Abstract
Photoalignment and photopatterning have been explored for decades as
promising methods for controlling the molecular arrangement in liquid crystal
(LC) devices. Light not only provides the energy required for these processes
but also delivers critical phase and polarization information to the material
systems.
Recent advancements have shown that photoalignment of liquid crystals
using azodye nanolayers enables exceptionally precise molecular alignment
within LC cells. Over the years, this technology has undergone numerous
refinements, unlocking innovative applications in photonics. Today, it plays a
vital role in optical signal processing, communications, and the
development of LC-based sensors for detecting external electric fields,
pressure, and even air and water flow—making them valuable tools for climate
change monitoring.
In his presentation, Prof. Chigrinov will introduce a physical model
of photoalignment and photopatterning grounded in rotational diffusion in
solid azodye nanolayers. He will further showcase emerging applications in
display and photonics, including:
- High-speed, high-resolution LC displays (e.g., field sequential
color ferroelectric LCDs)
- LC sensors and LC lenses
- Electrically and optically rewritable LC E-paper
- Photo-induced semiconductor quantum rods alignment for next-gen
displays
- 100% polarizers based on photoalignment
- LC smart windows with photopatterned diffraction structures
- LC antennas with voltage-controlled frequency
