A green-modification strategy for high-performance bamboo-based composites via persimmon lacquer and iron ion complexation
Natural bamboo-based fiber composites offer unique advantages in terms of renewability,eco-friendliness.However,challenges such as dimensional stability,and color stability in outdoor applications remain to be addressed.Here we report a straightforward method to impregnate an oriented bamboo fiber mats with a natural persimmon lacquer solution to fabricate bamboo scrimber composites.Due to the introduction of the complex,the water resistance of bamboo scrimber composite has been significantly enhanced,while having a slight negative effect on mechanical properties.The presence of the complex promoted a denser carbon structure,and the generated metal oxides acted as smoke inhibitors,reducing the total smoke production rate by 62.43％.Additionally,the bamboo scrimber exhibited excellent mildew resistance,hydrophobicity,and color stability,making it suitable for use in outdoor flooring,and furniture.Consequently,the results of this study provide a green processing strategy to prepare high performance bamboo-based fiber composites suitable for outdoor construction and furniture application.
