Sustainable Nanocellulose and Nanohydrogels from Natural Sources explores the use of biopolymers in specific application areas such as electronics, energy, consumer goods, packaging materials, therapeutics, water treatment and engineering, and what makes the particular polymer to engage it in these applications. This is an important reference source for those who would like to learn more about how biopolymeric nanocomposites are used in sustainability and environmental protection. Biopolymers, including plant and sea-based polymers, play an important role in the formation and maintaining the stability of industrial nanocomposites; their common functions being the surface modification and protection for the highly oxidative-unstable cores, as stable base for holding multiple targets, and as a shield for the inorganic and highly toxic metals. These biopolymer-based nanocomposites are being used for applications in the electronics, automobile, construction and biomedical sectors.
