NAIST Graduate School of Materials Science

Nanomaterials and Polymer Chemistry Laboratory

Based on the concept of “molecular technology”, the laboratory starts in 2015 for the research of functional materials and nanomaterials in the polymer chemistry field. The students who are interested in polymer synthesis and nanomaterials are welcome. The development of functional polymer materials requires organic synthesis, analytical methods, and design of the materials, which are covered in the laboratory. The education to be a researcher is diligently performed, through discussion, presentation, and joining academic conference and meetings.

Trimethylene carbonate derivatives and N-vinylamide derivatives, for example, are selected as biomaterial application (Fig. 1)

Thermal, pH, and light are used for the stimuli-responsive polymer materials, which change their chemical and physical properties (Fig. 2).

Nanoparticles, nanofibers, and nanofilms are design and prepared, using polymer-polymer interactions, such as van der Waals interaction and electrostatic interaction (Fig. 3).
