Surface modification and performance of jute fibers as reinforcement on polymer matrix: an overview

Abstract

Among the natural fibers, jute stands out for its characteristics. However, the adhesion between the fibers and the polymer matrix is limited and, therefore, physicochemical changes to the fiber surface are required. In this paper, the effects of physicochemical treatments on jute fibers were analyzed. We found alkaline treatment to be the most widespread and the use of chemical agents allows a greater addition of fiber to polymer matrices. Nevertheless, these treatments produce a lot of waste, increase the cost of production, and use toxic compounds. An environmentally friendly alternative is the application of irradiation to improve adhesion.
