A low-modulus modified bamboo fiber material and a preparation method thereof
By subjecting bamboo fibers to delignification and alkaline swelling treatment, combined with graft polymerization of specific monomers, low-modulus modified bamboo fiber materials were prepared. This solved the problems of high modulus and poor interfacial compatibility of bamboo fibers in biodegradable plastic composites, and achieved modified bamboo fiber materials with high flexibility and high strength, suitable for biodegradable films.

AI Technical Summary
When bamboo fiber is combined with biodegradable plastics, its high modulus leads to decreased film flexibility and poor interfacial compatibility, affecting processing, molding, and mechanical properties.
Low-modulus modified bamboo fiber materials were prepared by activating the hydroxyl groups on the cellulose molecular chain through delignification and alkaline swelling treatment, introducing a specific ratio of adipic acid, 1,4-butanediol, 1,3-propanediol and neopentyl glycol, and carrying out in-situ graft polymerization.
It reduces the modulus of bamboo fiber, improves interfacial compatibility with biodegradable plastics, enhances flexibility and mechanical strength, and is suitable for high-filler biodegradable films, reducing product costs while maintaining biodegradability.
