On the 25th, it was learned from the Bamboo Research and Development Center of the National Forestry and Grassland Administration (hereinafter referred to as the "Bamboo Center") that the center has successfully processed bamboo into high-strength, water-resistant, and biodegradable all bamboo thermosetting plastic shaped products using bamboo cell wall directional activation and molding technology. The relevant research results were recently published in the international journal "Nano" of the American Chemical Society. Bamboo is considered a potential material to replace petroleum based plastics due to its rapid growth, renewability, biodegradability, and environmental friendliness. However, bamboo has weak binding ability and often needs to be combined with adhesives or other materials, which may pose a risk of air pollution. In addition, compared with petroleum based plastics, bamboo has poor natural plasticity and relies on hydrothermal treatment for softening and shaping during the molding process, which to some extent limits its application range. This study adopted an innovative strategy to effectively remove some lignin from bamboo by combining the selective effects of sodium chlorite and acetic acid. At the same time, sodium periodate was used for directional aldehyde functionalization of sugar units, successfully reconstructing the structure and composition of bamboo cell walls. This reconstruction process not only significantly enhances the reactivity of bamboo units, but also greatly improves their plasticity Guo Dengkang, the first author of the paper and assistant researcher at the Bamboo Center, told Science and Technology Daily reporters that based on this, the team successfully converted the processed bamboo directly into thermosetting plastic products through hot pressing densification technology. This new type of all bamboo thermosetting plastic exhibits excellent mechanical properties comparable to hard plastics such as polystyrene, phenolic resin, and polyvinyl chloride. (New Society)
