“…The highest activation energy for neat CNF film could be due to the reinforcing effect of CNFs. E a can be written as a sum of strain energy (E s ) and binding energy (E b ) . E b is the energy required for ion to leave its site and E s is the kinetic energy an ion needs to distort structural of its environment to form a “doorway” through which it can jump to another site .…”

“…The use of nano‐structured BT with cellulose or cellulose derivatives to prepare cellulose nanocomposites has been studied but to much less extent than synthetic polymers. For example, ethyl cellulose and cyanoethyl cellulose were used as polymer matrix for BT nanoparticles to prepare nanocomposites with high dielectric properties. The use of BT nanoparticles with cellulose pulp fibers treated with a three‐layer structure of poly(diallyldimethylammonium chloride)/poly(sodium 4‐styrenesulfonate)/poly(diallyldimethylammonium chloride) to prepare paper sheets with high dielectric properties has been investigated .…”

Green nanocomposite films from cellulose nanofibers/barium titanate (CNF/BT) with high homogeneity were successfully prepared by doping different ratio of BT nanoparticles (2.5 to 25 wt%) into CNF. Scanning electron microscope images showed homogenous distribution of BT in the CNF matrix. Thermogravimetric analysis results showed good thermal stability of the prepared nanocomposites. X‐ray diffraction analysis showed that the tetragonality of BT grains was retained in the composite samples. Addition of BT nanoparticles to CNF resulted in decreasing the tensile strength properties of the films. The dielectric properties were analyzed in detail with respect to frequency ranged from 0.1 Hz to 5 MHz, temperature ranged from 289 to 373 K, and BT loading. The high k values of the CNF/BT films were attributed to spontaneous polarization of BT particles. The dielectric constant of the nanocomposites increased by addition of BT nanoparticles up to 5 wt% and decreased afterwards. Hopping ionic conduction was proved as a conduction mechanism of the prepared nanocomposites. The activation energy of the conduction ranged from 0.4 to 0.08 eV. Moreover, the values of activation energy decreased as the doping level of BT nanoparticles increased.

“…Apart from CA, Ethyl cellulose, Hydroxypropyl cellulose, Hydroxypropyl methylcellulose are the other most researched cellulose derivatives which have been used in micro/nanofiber fabrication. In the year 2004, ethyl-cyanoethylcellulose was first electrospun from EC and acrylonitrile in tetrahydrofuran, and about 200 nm of porous nanofibers were obtained [127][128][129][130]. The CECs have recently found applications in low-voltage organic field-effect transistors (OFETs) [131].…”

Electrospinning, for the last few decades, has been extensively acknowledged for its ability to manufacture a macro/nanofibrous architecture from biopolymers, which is otherwise difficult to obtain, in a cost effective and user-friendly technique. Such biopolymer nanofibers can be tailored to meet applications such as drug delivery, tissue engineering, filtration, fuel cell, and food packaging etc. Due to their structural uniqueness, chemical and mechanical stability, functionality, super-high surface area-to-volume ratio, and one-dimensional orientation, electrospun biopolymer nanofibers have been proven to be extremely beneficial. A parallel method in nonwoven methodologies called "Solution Blowing" has also become a potential candidate to fabricate a similar type of architecture from biopolymer fibers, and is gaining popularity among researchers, despite its recent advent in early 2000's. This review chiefly focuses on the fabrication of biopolymer macro/nanofibers via electrospinning and solution blowing, and several applications of such fiber architectures. Biopolymers include plant-and animal-derived biopolymers, such as cellulose, lignin, chitin, and chitosan, as well as proteins and their derivatives. The fabrication of biopolymer fibers from these biopolymers alone or as blends, predominantly with biodegradable polymers like Polyvinyl alcohol (PVA), Polyethylene Oxide (PEO), Polyethylene glycol (PEG), poly (lactide-co-glycolide) (PLGA) etc., or non-biodegradable polymers like polyamide, Polyacrylonitrile (PAN) etc., will be discussed in detail, along with the applications of several composites of such sort.

“…The enzymatic hydrolysis of office waste paper produced fermentable sugars used in preparation of Poly proposed for wearable electronic device [30]. Cyanoethyl cellulose derived from waste paper can also be used for organic field-electric transistors (OFETs) [31,32], such organic based components are receiving attention for their low-cost, ease of processing, flexibility and lightweight circuits suitable in applications for ultra-low power electronics such as radio frequency identification (RFID) tags, biodegradable electronics for medical implant, sensor devices and so on.…”

Paper is a perfect example of the circular economy as it remains the furthermost recycled product in Europe, creating significant environmental benefits and raw materials resources to the industry. Indeed, maintaining a consistent level of quality whilst limiting the environmental footprint of the product has become a major challenge for the industry. In this direction, paper is proving to be the promising feedstock for biorefinery and biomaterials. The future of paper recycling is slowly going beyond fibre recovery to address the needs of other industries because for the earth's environmental well-being various paper products need to be recycled and reused persistently. In this article, we outline the ambitious use of wastepaper (WP) for high-value applications such as; production of cellulose nanocrystals (CNC), composite reinforcement, high performance electrical components and biofuels.
