Date & Time: Apr 19 2024 | 11:30am Location: Science Learning Center, Room 345 Over the past years nanocellulose has proven to be one of the most prominent green materials of modern times. Nanocellulose is derived from the most abundant natural polymer, cellulose, from various physical and chemical processes. Even though cellulose has been widely utilized for several decades, nanocellulose has emerged as a prominent material in the last two decades. Nanocellulose can be mainly divide into three types: cellulose nanocrystals (CNCs), cellulose nanofibrils (CNFs), and bacterial cellulose (BC), having a size about 100nm. Also, due to different sources and extraction method applied, the morphology, particle size and characteristics of each category can vary. Although nanocellulose is derived from cellulose, it possesses completely different characteristics from original material. It shows enhanced crystallinity, high surface area, better mechanical properties, alignment and orientation, biodegradability, biocompatibility, and low toxicity. Nanocellulose have been surface-modified in various ways to enhance their characteristics and expand their potential applications, owing to their large specific surface area and the presence of numerous hydroxyl groups on their surface. This presentation highlights preparation method, chemical surface modifications, and applications of nanocellulose, especially cellulose nanocrystals (CNCs).
