Abstract:
To improve the mechanical properits of individual bamboo fiber, the ultrasonic treatment was performed to the bamboo fibers modified by nanoparticles. The influence of ultrasonic frequency and ultrasonic treatment time on mechanical properties of individual modified bamboo fiber was also studied. Field emission environmental scanning electron microscope (FEGSEM), hight precision machanical property tester ( HPMPT) and confocal laser scanning microscope (CLSM) wewe used to characterize the surface morphology, the load of CaCO3 and mechanical properties of individual modified bamboo fiber subjected to ultrasonic treatment. The results showed that the tensile strength and elasticity modulus (MOE) of single modified bamboo fiber increased by 15.99% and 7.81%, respectively, compared with the untreated bamboo fiber. The optimal process conditions for individual bamboo fiber modified byultrasonic treatment were determined to be an ultraonic frequency of 45 kHz and an ultrasonic time of 10 min.
Key words: calcium carbonate nanoparticle, impregnation, bamboo fiber, ultrasonic treatment, ultrasonic frequency, ultrasonic time, mechanical property
