Research Interest
Overview
We are interested in nano-structured systems of soft materials which exhibit the great potential for practical applications. Our goals are (1) to understand the structure-property relationship of the materials, (2) to understand the kinetics to achieve equilibrium and (3) to control the structure and dynamics for achieving high performance.
Polyelectrolyte Complex (Coacervation) Process
Liquid-liquid phase separation (LLPS) induced by various associative interactions including electrostatic, hydrophobic and π- π interaction is a great interesting process. We aim to understand the LLPS in aqueous media with a merit of model synthetic polymer systems, and to provide new insight for cellular signaling, regulation and organization as well as neurodegenerative diseases.
Characterization of Nano-structured Soft Materials: Block Copolymer Solution
Complex coacervation driven core micelle (C3M) and hydrogel (C3H) in aqueous media has been of interest in past years due to the superior potential for biocompatible applications including RNA/DNA delivery system, tissue engineering, and bio-coating process. We focus on understanding structure and dynamics of the nanostructures which are critical determinants for structural stability, cellular transportation and uptake in physiological conditions by using scattering method and rheological model.
Polyisobutylene based Elastomer
Polyisobutylene (PIB) and butyl rubber (poly(isoprene-co-isobutylene), IIR) are widely used in industrial and commercial rubber products such as tire bladder and shoes outsole due to low gas permeability and good damping property. We purpose to improve dispersion and mechanical properties of butyl rubber/inorganic composite.
