摘要：

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.　©　(2013)　Trans　Tech　Publications,　Switzerland.
