Influence of Chemical Treatment on Natural Fibers: A Review

Abstract

Natural fiber composites are proven to be biodegradable nowadays and are applicable to several sectors. Many natural fibers are used as reinforcements in polymeric composites with and without pretreatments. Many studies have reported that the chemical pretreatment to natural fibers enhance the surface properties of the fibers and which in turn improves the strength of the composite. Though there are several treatment techniques, sodium hydroxide is majorly used as the chemical for treating the fiber. Apart from this, there are several other treatments namely benzoylation, peroxidation, silane treatment, etc. The present study gives a clear picture of various chemical pretreatments given to the natural fibers and their processing methodologies. These treatments are bond between reinforcement surface and also increases its strengthening mechanism.
