Research Overview

Amphiphilic block copolymers can self-assemble to form nanoparticles (micelles) consisting of a hydrophobic core and hydrophilic shell in aqueous media. We developed a series of nanoparticles with a catalytic core and an inert thermoplastic shell. These nanoparticles are used as latent catalysts to control reactions because the catalyst is only exposed when the shell is collapsed by heating.
We also developed a series of polymers including a thermal rearrangement system. We synthesized polymers with thermal rearrangement moieties in the polymer side chain, and the resulting polymer films showed an increase in the refractive index of 0.01. These polymers are suitable for optical devices.

Research Subjects

  • 1.Synthesis and self-assembly of novel amphiphilic block copolymers for nanostructured objects.
  • 2.Synthesis of polymers with designed architectures and their applications.
  • 3.Synthesis and characterization of stimuli-responsive materials.

Introduction:

All living things are composed of soft, flexible materials that can respond to many kinds of external stimuli such as temperature and light. Polymers, often called plastics, are typical soft, flexible materials. We are focusing on block copolymers, which consists of two or more chemically different polymer chains connected at one chain end. We are investigating how controlling the self-assembly of these polymers can produce many kinds of unique nanometer-sized periodic structures and we are developing their functionalities.
