Outline of Final Research Achievements

Biomimerals, such as bone and tooth, are inorganic-organic composites having well-organized structures. In this study, fundamental factors that influence composite formation were investigated to develop well-organized inorganic-organic fusion materials through the methods inspired by formation and structure of biominerals. Composites of organic polymer and calcium phosphates with various microstructures were fabricated through the biomimetic processing. Temperature-responsive material with bone-bonding ability was developed from a polysaccharide by the addition of inorganic salts. Titanium oxides and iron oxides, with appropriate surface characteristics, were found to be useful as substrates that form composites with hydroxyapatite using a type of aqueous solution mimicking body fluid. These findings lead to fabrication of composite materials with designed morphology as well as functionality through an environment-friendly process based on the optimized inorganic-organic interactions.
