Exploration and preparation of multifunctional bamboo based on a green wax-based composite system

This research was guided by the technical requirements for bamboo to permanently maintain its dimensional stability and antifungal properties and focused on the green and environmentally friendly construction of a wax-based composite system and its effects. The wax-based system consisted of a physical combination of paraffin wax and bamboo and the chemical combination of paraffin/stearic acid. The heterogeneous interface characteristics of the wax-based composite system and bamboo were analyzed using Raman micro-spectroscopy, among other methods, to reveal its effects on the dimensional stability, antifungal, and mechanical properties of bamboo. Our results showed that the water absorption thickness swelling rate of the bamboo showed few changes, while the antifungal and hydrophobic properties also played a significant role. In addition, the mechanical properties improved compared to raw bamboo, offering a wider range of application prospects for bamboo products.
