“…Gao et al [ 118 ] used cellulose nanofi bers as spacers and electrolyte reservoirs to construct a hierarchical rGO structure, and this hybrid structure shows high capacitance (207 F g −1 ). Through the introduction of carbon black particles as spacers, the agglomeration of graphene sheets during fi ltration is mitigated to a large extent.…”

“…The fi rst is to fabricate porous graphene frameworks, [ 90,115,116 ] and the other is using spacers, such as CNTs and carbon black. [117][118][119][120] Chen et al [ 115 ] used polymethyl methacrylate (PMMA) as a hard template to fabricate a 3D porous graphene fi lm, which showed controllable and uniform macropores and a tailorable microstructure. The graphene fi lm provides macropores for ion-buffering reservoirs and higher ion diffusion.…”

“…The cycle performance test after 2000 charge/discharge cycles of crosslinked GAs, indicated promising cyclic stability. Introducing "stabilizer" or "spacer" into GAs is one of the most promising ways to enhance the supercapacitor performance, especially in using pseudo-active materials, such as metals (Li et al, 2011), metal oxides (Yu et al, 2011;Zhu et al, 2011;He et al, 2013a,b), conductive polymers (Huang et al, 2012;Tai et al, 2012;Gao et al, 2013;Ye et al, 2013), and carbon nanotubes (Zhu et al, 2012). Ye et al (2013) developed 3D hierarchical graphene/ polypyrrole nanotube hybrid aerogels for supercapacitor applications.…”

Two dimensional (2D) graphene has become one of the most intensively explored carbon allotropes in materials science owing to attractive features like its outstanding physicochemical properties. In order to further practical applications, the fabrication of self-assembled 2D individual graphene sheets into 3D graphene aerogels (GAs) with special structures and novel functions is now becoming essential. Moreover, GAs are ideal as supports for the introduction of nanoparticles, polymers, and functional materials to further enhance their applications in broad areas. GAs have light weight, large surface area, good compressibility, extensibility, and high electrical conductivity. They have been used as efficient electrodes for batteries, in supercapacitors, and in sensors and actuators. This critical review mainly addresses recent progress in the methods used for their synthesis, their properties, and applications for energy storage, and in sensors and actuators. Furthermore, to assist advanced research for practical applications of these emerging materials, the technical challenges are discussed, and future research directions are proposed.

“…Nanocellulose that is produced from the renewable lignocellulose materials has improved mechanical properties, such as high surface area-to-volume ratio and high aspect ratio [8][9][10]. Nanocellulose often replaces well-known material such as glass and certain polymers, which are not biodegradable at ambient conditions, in order to create new specific nanocomposites, adsorbents, and functional materials for the electrodes in the chemical sources of power and optoelectronic devices [11][12][13][14][15][16], biodegradable plastics and paper with special characteristics [17][18][19].…”

The development of the nanomaterials with the advanced functional characteristics is a challenging task because of the growing demand in the market of the optoelectronic devices, biodegradable plastics, and materials for energy saving and energy storage. Nanocellulose is comprised of the nanosized cellulose particles, properties of which depend on characteristics of plant raw materials as well as methods of nanocellulose preparation. In this study, the effect of the mechanochemical treatment of bleached softwood sulfate pulp on the optical and mechanical properties of nanocellulose films was assessed. It was established that the method of the subsequent grinding, acid hydrolysis and ultrasound treatment of cellulose generated films with the significant transparency in the visible spectral range (up to 78 % at 600 nm), high Young's modulus (up to 8.8 GPa), and tensile strength (up to 88 MPa) with increased ordering of the packing of the cellulose macromolecules. Morphological characterization was done using the dynamic light scattering (DLS) analyzer and transmission electron microscopy (TEM). The nanocellulose particles had an average diameter of 15-30 nm and a high aspect ratio in the range 120-150. The crystallinity was increased with successive treatments as shown by the X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FTIR) analysis. The thermal degradation behavior of cellulose samples was explored by thermal gravimetric analysis (TGA).
