Abstract
Archaeological waterlogged woods become considerably fragile over time because of the chemical hydrolysis and the deterioration by microorganism in a wet buried environment. Drying archaeological waterlogged wood often leads to drastic shrinkage and deformation due to cell wall decomposition. Once such shrinkage and deformation has occurred it is difficult to return the wood to its initial size and shape by re-immersion in water. Recently, the superabsorbent polymer (SAPs) which was prepared by polymerization of acrylic acid blended with cross-linking agent in the presence of an initiator to form a poly-acrylic acid was applied for bacterial cellulose (BC). This cross-linked BC gel showing unique one-dimensional shrinkageswelling behaviors [1]. Therefore, in this study, we applied this technique for archaeological waterlogged wood treatment.
