Alkali-treated and silanated luffa fiber reinforced poly(butylene succinate) composites: A study of mechanical and water absorption characterization
As a degradable polymer material, polybutylene succinate (PBS) has the disadvantages of high cost, slow crystallization rate, and low strength modulus. Reinforcing modification with plant fibers is a popular method. A unique three-dimensional network structure was found in luffa fiber (LF). Compared to other plant fibers, this fiber has excellent mechanical strength due to its unique three-dimensional structure. Its structure allows it to maintain the integrity of the reinforcement phase in the polymer aggregate, overcoming the dispersion and defects of short fiber reinforcement. Herein, the LF was treated with alkali treatment and silanated with three coupling agents and pre-impregnation methods to improve interfacial properties with the PBS matrix. Then it was laminated with polybutylene succinate to prepare a PBS/LF composite board with three layers of LF. The performance of the composite material using the KH550 coupling agent was improved the most. The tensile strength and modulus of the material were increased by 24.9% and 82.9%, respectively, the flexural strength and modulus were increased by 21.7% and 18.5%, and the impact strength was increased by 12.5%. The water absorption weight gain rate is also the lowest, about 3.5%. For the LF-reinforced PBS, the preparation method is simple, and the reinforcement effect is better, that the cost was effectively reduced, and the application field of the PBS green material was expanded. A new possibility for the development of green degradable polymer composites was provided.
