tailieunhanh - Effect of atmospheric plasma treatment on mechanical properties of jute fiber and interface adhesion between fiber and resin

The surface treatment by physical method of jute fiber using air plasma was investigated. Fiber was treated by the atmospheric plasma with various conditions of power 50W and different treatment times (from 1 min to 7 min). After treatment, the characteristics of fiber changed remarkably and fiber surface observed by SEM analyze showed a better morphology for adhesion. The result showed that tensile strength and Young’s modulus of jute fiber were slightly improved, however there was a remarkable improvement interface adhesion between fibers and polypropylene (PP) resin. Especially, when combine physical method and chemical method, the interfacial adhesion and mechanical properties of jute fibers were significantly improved | Journal of Chemistry Vol. 45 5A P. 201 - 206 2007 EFFECT OF ATMOSPHERIC PLASMA TREATMENT ON MECHANICAL PROPERTIES OF JUTE FIBER AND INTERFACE ADHESION BETWEEN FIBER AND RESIN Received 16 August 2007 TA THI PHUONG HOA NGUYEN THI THANH BINH NGUYEN CHAU GIANG Polymer Center Hanoi University of Technology SUMMARY The surface treatment by physical method of jute fiber using air plasma was investigated. Fiber was treated by the atmospheric plasma with various conditions of power 50W and different treatment times from 1 min to 7 min . After treatment the characteristics of fiber changed remarkably and fiber surface observed by SEM analyze showed a better morphology for adhesion. The result showed that tensile strength and Young s modulus of jute fiber were slightly improved however there was a remarkable improvement interface adhesion between fibers and polypropylene PP resin. Especially when combine physical method and chemical method the interfacial adhesion and mechanical properties of jute fibers were significantly improved. I - INTRODUCTION II - EXPERIMENTAL Natural fiber reinforced composites have recently increased concerns of scientists and technologists because of many advantages. Natural fibers are abundant with various species can be recyclable and biodegradable and therefore are very potential in manufacturing environmental friendly polymer composite. It is however important to improve interface adhesion properties between natural fiber and resin. Among several fiber treatment methods plasma treatment is a new physical method which is regarded as a dry surface processing method for adhesion improvement without waste liquid. Moreover plasma treatment can modify surface without obstructing basic properties of fiber. In this research atmospheric plasma treatment has been applied to improve adhesion properties between jute fiber and polypropylen PP resin. 1.
