Superior crack initiation and growth characteristics of cellulose nanopapers

Preparation, Properties and Use of Nanocellulose from Non-Wood Plant Materials

“…Low consumption of NC allows production of the paper and cardboard with properties that meet the requirements to appropriate standards and replacement of synthetic reinforcing materials [123]. The increase in the values of the indicators of paper and cardboard occurs due to the creation of new hydrogen bonds between the fibers of cellulose and NC, which is confirmed by other authors [124,125]. NC often replaces such well-known material, as glass and certain polymers, which are not biodegradable at ambient conditions.…”

“…Cellulose nanomaterials, also known as nanocellulose, that can be produced from lignocellulosic biomass have attracted extensive attention due to their unique properties (Du et al 2019). Recently, self-assembled cellulose nanopaper (CNP) formed from a nanocellulose suspension has been widely studied due to its superior mechanical properties, tunable optical properties, high thermal stability, low thermal expansion coefficient, excellent oxygen barrier, and biodegradability (Miao et al 2020). CNP has been highlighted as an alternative to traditional plastic.…”

Multifunctional Cellulose Nanopaper with Superior Water-Resistant, Conductive, and Antibacterial Properties Functionalized with Chitosan and Polypyrrole

“…With increasing concern about the depletion of nonrenewable resources and environmental issues, lignocellulosic biomass has been recognized as a promising alternative to petroleum resources, which have been utilized to produce biofuels, chemicals, and biomaterials. − Cellulose nanofibrils (CNFs), mainly extracted from lignocellulosic biomass, have received a great deal of attention due to their excellent physical, mechanical, and chemical properties such as high elastic modulus (29–36 GPa) and tensile strength (2–6 GPa), large specific surface area (up to 600 m 2 /g), high aspect ratio (larger than 100), low density (1.32–1.58 g/cm 3 ), and reactive surfaces, along with biodegradability and renewability. − Due to their high aspect ratio and semicrystalline structure, CNFs exhibit remarkable tendency to form three-dimensionally entangled networks suitable for fabricating the cellulose nanopaper (CNP) by a self-assembly process such as vacuum filtration or casting. , CNP has been a hot topic which has attracted extensive interest from both academia and industries . Recent studies have shown that CNP is a promising material for use in many interdisciplinary fields such as electronic and photonic devices, , energy storage electrodes and separators, , electromagnetic interference (EMI) shielding materials, , sensors, , and so forth, in light of its good thermal stability, low thermal expansion coefficient (<10 ppm/K), tunable optical properties, and superior mechanical properties …”
