Surface-Modified Natural Fiber Composites

Research is now being conducted by scientists around the world with the goal of enhancing the quality of goods that are environmentally friendly and sustainable in order to maintain the environment and biodiversity. People are turning more and more to natural fibers as a replacement for synthetic and hazardous materials due to the macro and micro features of natural fibers, as well as their environmentally favorable behaviors. It is possible to overcome some of the disadvantages of natural fiber, such as its hydrophilic and biocompatibility features, by employing a wide range of chemical processing and surface modification techniques. The primary objective of the process of chemically changing natural fiber is to decrease the hydrophilic properties of the fiber and to improve the hydrophobic matrix compatibility of the fiber. Chemical treatments are simple to carry out and need less energy than other methods. The changed surface shape of the fiber surface that was brought about by the chemical reaction made it feasible for better mechanical interlocking to take place. In this chapter, we will discuss the treatment of fiber surfaces that have been changed, as well as the physical, chemical, and biological effects of these treatments.
