Preparation of bacterial cellulose for xylitol-reinforced waterlogged wood

Reinforcement is a critical aspect in the preservation of waterlogged wooden artifacts to ensure their long-term stability. In this study, we investigated the use of bacterial cellulose compounded with xylitol as a reinforcement material for simulated waterlogged wooden artifacts at varying concentrations. Evaluation of the reinforcement effects was based on indicators such as antishrinking efficacy, mechanical strength, and microscopic morphology. Our findings revealed that bacterial cellulose alone had limited effectiveness but showed enhanced reinforcement when mixed with xylitol. Optimized conditions resulted in remarkable improvements in bending strength (94.5 MPa) and deformation (20 mm) of the reinforced wood. This study offers novel insights and a scientific foundation for the reinforcement of waterlogged wooden artifacts, with potential implications for their preservation in cultural heritage conservation practices.
