Over the decades, this particular i eld of study has become more interesting, leading
to the advancement of nanocellulose characteristics. h is is because many researchers
have found that the properties of nanocellulose play an important role in nanocom-
posite. A better understanding of organic and polymer chemistries enables the current
research to look deeper into the interaction between polymer matrix and nanocellu-
lose, hence, leading to the advancement of nanocellulose values

Application of Nanocomposites Based on Nanocellulose
h e development and the application of polymeric composite materials i lled with
nanosized rigid particles (essentially inorganic) has attracted both scientii c and indus-
trial interest. h e development of new polymer electrolytes is needed for many kinds of
electrochemical applications such as separators in high-energy density lithium batter-
ies. Poly(oxyethylene) (POE)-based polymer electrolytes are the most commonly stud-
ied, due to their cationic solvation ability [188].
Reinforcement using nanoi ber is nowadays dispersed in many i elds not only in hard
composite but in thin i lm too. Consequently, its application could cover pretty much in
