“…The main advantage of the APS method is that there is no need for purification of the raw material before nanocellulose production. Since 2011, the APS method has become widely used and a number of articles about obtaining of CNC by the APS method from different feedstock, such as cotton linter [ 26 , 30 , 31 , 32 , 33 ], flax [ 26 , 34 ], hemp [ 26 , 34 ], triticate [ 26 ], micro crystalline cellulose [ 26 , 33 , 34 , 35 , 36 ], wood pulp [ 26 , 30 , 32 , 37 , 38 ], bacterial cellulose [ 26 , 39 , 40 ], borer powder of bamboo [ 41 ], cornhob [ 42 ], Lyocell [ 43 ], oil palm empty fruit bunch [ 44 ], coconut fiber [ 45 ], and sugarcane bagasse [ 29 , 46 ], have been published.…”

Ammonium persulfate has been known as an agent for obtaining nanocellulose in recent years, however most research has focused on producing cellulose nanocrystals. A lack of research about combined ammonium persulfate oxidation and common mechanical treatment in order to obtain cellulose nanofibrils has been identified. The objective of this research was to obtain and investigate carboxylated cellulose nanofibrils produced by ammonium persulfate oxidation combined with ultrasonic and mechanical treatment. Light microscopy, atomic force microscopy (AFM), powder X-Ray diffraction (PXRD), Fourier-transform infrared spectroscopy (FTIR), thermogravimetric analysis (TGA) and Zeta potential measurements were applied during this research. The carboxylated cellulose suspension of different fractions including nanofibrils, microfibrils and bundles were produced from bleached birch Kraft pulp fibers using chemical pretreatment with ammonium persulfate solution and further defibrillation using consequent mechanical treatment in a high shear laboratory mixer and ultrasonication. The characteristics of the obtained nanofibrils were: diameter 20–300 nm, crystallinity index 74.3%, Zeta potential −26.9 ± 1.8 mV, clear FTIR peak at 1740 cm−1 indicating the C=O stretching vibrations, and lower thermostability in comparison to the Kraft pulp was observed. The proposed method can be used to produce cellulose nanofibrils with defined crystallinity.

“…Recently, Vecbiskena and Rozenberga [36] obtained NFC via ammonium persulfate oxidation of bleached birch Kraft pulp and unmodified BC pellicles and prepared chitosanmatrix films in packaging industry or biomedicine. Chitosan matrix tuned by BC nanofibers resulted in an increase of the mechanical and biological properties of the biocomposite films.…”

Cellulose is the most abundant biomass resource in the world. It can be transferred to various water soluble derivatives, biochemicals, and materials. In the second half of the 20th century, nanocellulose was extracted with unique properties such as optical transparency, high strength, and high surface area. These new forms of cellulose can be combined with other materials, mainly biopolymers, to form multifarious composites, which are used in all applications of human life. For convenience, to introduce the recent development of these cellulose-based functional composites, we divided them to seven categories, including biological applications, water treatment, sensor, reinforcing agent, energy storage materials, Pickering emulsion stabilizer, and other versatile applications. The preparation, properties, and applications of these functional composites were depicted.
