(Department of Chemistry, Zhejiang University, Hangzhou 310027) m Abstract The conservation of historic stones is a crucial and arduous task. Now, stone conservation is primarily achieved through surface treatments by the use of organic materials, but the protective effects do p not satisfy the protectors. So it has been focused on to develop new materials or methods. In this paper, we s . have prepared a new protective material by a bioinspired method, in which chondroitin sulfate was selected as a controlling template and the supersaturated solution of calcium oxalate as a stock solution, and t
