the ef ect of inorganic nanophases are also addressed to demonstrate the real potentiali-
ties of bacterial cellulose in the polymer nanocomposites. Chapter 2 also discusses in
detail the bacterial cellulose-based hybrid nanocomposite materials. Chapter 3 sum-
marizes the new trends in the use of nanocellulose (nanowhiskers and nanoi brillated
cellulose) as reinforcement of dif erent types of polyurethane systems.
Chapter 4 discusses in detail the bacterial cellulose-reinforced renewable polymer-
matrix-based composites. h e techniques used to prepare the nanocomposites include
