“…However, the addition of CNF at higher loading has resulted in the agglomeration and formation of voids in the polymer network, which increased the mobility of polymer chains. Other DMA data also showed remarkable improvements in the storage modulus over a wide range of temperature for a large number of polymer nanocomposites with nanocellulose, such as poly(styrene‐co‐butyl acrylate), unsaturated polyester, poly(butylene succinate), nanoclay, poly(vinyl acetate), PLA, and natural rubber …”

Nanocellulose has received increasing attention in science and industry in recent years as a nanoscale material for the reinforcement of polymer matrix composites due to its superior mechanical properties, renewability, and biodegradability. New nanocellulose sources, modifications, and treatments are under development to reduce the high energy required during production and to create a more suitable industrial-scale production process. Thus, this paper reviews plant-based nanocellulose composites and their properties, with a focus on their thermal-related characteristics. The purpose of this review is to establish for readers the impact of the incorporation of nanocellulose on the thermal and dynamic mechanical properties of nanocellulose composites. Understanding of the thermal properties is important for researchers to assess the suitability of the nanocomposites for a variety of applications in response to new and evolving societal requirements.The first NFC was produced from wood by using high-pressure homogenization without any pretreatment. 11,12 However, this method is a very energy-intensive process. Therefore, chemical treatments such as 2,2,6,6-tetramethylpiperidine-1-oxyl radical (TEMPO) oxidation combined with mechanical and chemical

“…It was invented in the early 1990s with similar properties to poly(ethylene) and poly(propylene) [25], and has shown great potential in many applications including automotive and packaging industries and tissue engineering [26][27][28]. PBS has been processed with CNCs to improve its mechanical, thermal, and barrier properties, its biodegradability, and to control its morphology and crystallization [29][30][31][32]. Different approaches have been used to improve the interfacial adhesion between CNCs and PBS.…”

Despite the many interesting properties of cellulose nanocrystals (CNCs), their hydrophilicity is one of the main challenges for their processing with hydrophobic polymers and matrices. To overcome this challenge, this paper describes the preparation of brush-like CNCs with tailored surface properties by grafting alcohols of different chain lengths onto their surfaces. Ethanol, 1-butanol, 1-hexanol, and 1-octanol were grafted on the CNC surface using 2,4-toluene diisocyanate (TDI) as a linker. The CNCs were characterized for their structural, morphological, surface, and thermal properties. Because of the grafting, the water contact angle of the CNCs significantly increased from 32° to up to 120°, which was dependent on the chain length of the grafted alcohol. The thermal stability of the CNCs was also improved, mainly as a result of the reaction of TDI with the CNC hydroxyl groups. Later, the CNCs were used to reinforce films of poly(butylene succinate) (PBS), which were then characterized using dynamic mechanical analysis (DMA) and thermogravimetric analysis (TGA). An increase of up to two-fold in the storage modulus was observed using DMA, which was dependent on the chain length of the grafted alcohol. However, no change in the glass transition temperature or degradation temperature of PBS was detected. This approach is proved efficient for tailoring the surface properties of CNCs towards excellent interfacial adhesion in their composites.

“…A growing number of researchers have paid attention to prepare transparent cellulose films with excellent mechanical properties, which can be used in a wide range of applications . In recent years, biocomposites composed by cellulose and other bio‐based matrixes (polylactide, biopolyesters, or PU) have been extensively investigated . Because of different polarities in these systems, the interfacial adhesion is relatively low.…”

This study describes a green method for preparing all-cellulose nanocomposites through a dissolution and regeneration process. Cotton linter pulp was dissolved in 7 wt % NaOH/12 wt % urea aqueous solution precooled to −12 C. Self-assembly of cellulose molecules into nanostructured cellulose fiber is achieved by using water addition and controlling the temperature to regenerate cellulose. By changing the microenvironment of the cellulose solution, the morphology of the nanostructured cellulose fibers and the mechanical properties of the regenerated cellulose films can be tuned. Then, a series of regenerated cellulose films have been prepared and characterized from various aspects. Compared with other all-cellulose films in the literature, the regenerated all-cellulose nanocomposite films prepared in this work exhibited good optical transparency, thermal stability, and excellent tensile strength (up to 135 MPa) when the regeneration temperature was adjusted to 50 C. This work provided a green and promising approach to prepare high-performance and environmentally friendly all-cellulose nanocomposites.These two authors contributed equally to this work.
