Synthesis of Natural Rubber-Based Completely Green Bionanocomposites
Bionanocomposites are novel materials born out of the growing interest in nanomaterials and in the development of materials derived from renewable sources. Some biopolymers which are naturally available in abundance can also be, directly or after modification, used to replace the conventional fillers leading to partial biodegradation. Significant developments have been seen in the realm of polysaccharides such as starch, cellulose and chitin in recent years due to several advantages like abundant availability, low cost, renewability, biodegradability and non-toxic nature. Polysaccharides are also potential renewable sources of nanosized reinforcements in the form of whiskers as well as nanocrystals. The chapter discusses biocomposites and bionanocomposites of NR with various polysaccharides in the native as well as modified forms. The effect of filler loadings, chemical modification and other factors on mechanical and sorption properties is also discussed in detail.
