Research Abstract

The objective of our research is the development of environment-friendly polymers promising application to a sustainable society. Tunicate cellulose and bacterial cellulose were used as native cellulose materials. Cellulose and imogolite, naturally occurring inorganic polymer, were treated under various conditions to produce nano-sized rods. Structural control of the nano-rods by magnetic field was examined.
