Research Abstract

In this research project, the growth technique of target materials on previously prepared frameworks in tissue engineering was tried to apply to inorganic material processing. Preparation of panoscopic materials having controlled structures in all length scales were investigated using the technique. Macroscopic morphology, mesoscopic arrangement and microscopic crystal phase and shapes were spontaneously controlled with organic framework in the aqueous processing. The results of this project were classified into three phases. (1) Preparation conditions including pH, concentrations and temperature were found for crystal growth of functional oxides, such as titanium dioxide and zinc oxide, on organic frameworks in aqueous solutions at low temperature. Control of the chemical potential of the soluble species was essential for the direct preparation of crystalline phases. (2) Influence of co-existing species on the morphology of crystals was investigated. The presence of specific anions induced miniaturization of growth units and unique architectures, such as nanosheets, self-similar structures and helical forms were produced. (3) Organic fibers, hydrogel of polyacrylamide and surfactant foams were found to be useful as a framework for deposition of inorganic materials. The combination of the results of (1), (2) and (3) led the preparation of panoscopic materials consisting of controlled macroscopic morphology, mesoscopic arrangement of subunits and microscopic crystalline phase and shapes..
