Abstract
The biomimetic method of achieving dense platelike grain growth of the high temperature superconducting ceramic YBa2Cu3O7 (YBCO) has been studied. By using various organic matrices (dextran and chitosan) having different molecular structures, the final size and arrangement of the platelike YBCO grains exhibit significant differences, possible reasons for which are discussed. The different organic matrices used also indirectly affect the superconducting properties of the YBCO formed. By elucidating the role of the organic matrix in the biomimetic synthesis process in this way, the whole process could be controlled more precisely, leading to structural and electrical properties of the final product more desireable for specific applications.
