TAILIEUCHUNG - Air-plasma treatment of bamboo fiber for polypropylene composite application

In this study, the air-plasma generated by radio-frequency was used to treat bamboo fiber. The treatment parameters were studied to find the suitable condition. The testing on tensile strength, tensile modulus, module Weibull and elongation to break of the fiber, the measurement of contact angles and the SEM analysis showed that at the high frequency of 12 kHz, power 50 W and treatment time of 5 minutes, after air-plasma treatment the tensile strength and tensile modulus of bamboo fiber increased more than double ( and ), the contact angles increased remarkably and treated fibers have cleaner surface. | Journal of Chemistry Vol. 45 5A P. 196 - 200 2007 AIR-PLASMA TREATMENT OF BAMBOO FIBER FOR POLyPROPyLENE COMPOSITE APPLICATION Received 16 August 2007 TA THI PHUONG HOA DO THI cuc NGUyEN HOANG AN Polymer Centre Hanoi University of Technology SUMMARy In this study the air-plasma generated by radio-frequency was used to treat bamboo fiber. The treatment parameters were studied to find the suitable condition. The testing on tensile strength tensile modulus module Weibull and elongation to break of the fiber the measurement of contact angles and the SEM analysis showed that at the high frequency of 12 kHz power 50 W and treatment time of 5 minutes after air- plasma treatment the tensile strength and tensile modulus of bamboo fiber increased more than double and the contact angles increased remarkably and treated fibers have cleaner surface. The adhesion between bamboo fiber and polypropylene PP as well as PP containing maleic anhydride grafted PP evaluated by droplet method showed that the interfacial shear strength IFSS of the treated fiber increased at PP and at PP-MA-PP compared with untreated fiber SEM image showed a better adhesion between fiber and polymer. Compared to treatment by silane coupling agent airplasma treatment can improve both the mechanical properties of fiber and adhesion while silane coupling agent only the adhesion. I - INTRODUCTION In recent years there has been renewed the interest in using the natural fiber to replace glass fiber to get polymer composite which is ecofriendly. Vietnam is the country where bamboo is abundantly available and of diversified species polypropylene PP has a wide range of application and a high value of property price therefore there is a good potential to use bamboo fiber for polypropylene composite application to get a motivated combination of environmental friendliness and economical feasibility. However due to very different natures of natural fiber and polymer there is a poor wet ability and
