Advancements in nitrated nanocellulose: from structural insights to energetic applications

Abstract This review explores the structural and chemical properties of nitrated nanocellulose, highlighting its transformative potential in energetic applications. Derived from cellulose nanocrystals (CNCs), cellulose nanofibrils (CNFs), and bacterial nanocellulose (BNC), nitrated nanocellulose combines the inherent advantages of nanocellulose such as mechanical strength, large surface area, and biodegradability with enhanced energetic properties achieved through nitration. The impact of nitrated nanocellulose in energetic materials extends to its ability to contribute to greener, more sustainable energy solutions by reducing reliance on traditional petrochemical-based components. The review delves into various nitration techniques, including mixed acid and catalytic systems, which convert nanocellulose into nitrocellulose with tailored properties. These nitrated forms exhibit improved mechanical stability, reduced sensitivity to external stimuli, and enhanced safety profiles, making them promising candidates for applications in explosives, propellants, and energy storage. The review concludes by outlining future research directions, emphasizing the need for further exploration of synthesis methods, and integration into advanced energetic systems to fully unlock the transformative potential of nitrated nanocellulose in materials science and energetic technologies.
