| Outline of Final Research Achievements |
Imogolite, a natural aluminosilicate nanotube, has Si-OH on the inner wall surface and Al-OH groups on the outer surface, while halloysite has Si-O-Si on the outer surface and Al-OH groups on the inner lumen. With nanotubes, selective chemical modification of the nanotube surface or inner lumen is possible with organic molecule containing phosphate groups. Various (organic/inorganic) hybrids were prepared from polysaccharides and oligopeptides having functional groups that specifically interact with Al-OH. By utilizing the intermolecular interaction between inorganic nanotubes and organic polymers from natural origin, novel environmentally friendly hybrid materials were prepared and their structure-physical properties relationships were clarified.
