Synergistic effects of chloride anions and carboxylated cellulose nanocrystals on the assembly of thick three-dimensional high-performance polypyrrole-based electrodes

Spatioselective surface chemistry for the production of functional and chemically anisotropic nanocellulose colloids

“…Surface modification of CNCs by TEMPO-oxidation has been also shown to induce synergistic interactions in composites, as shown in the case of polypyrrole/CNC films. 242 In this case, it was demonstrated that the carboxylate groups at the CNC surface, increased aerial capacitance, energy density, and cycling stability in prepared supercapacitors.…”

Interconnected and high cycling stability polypyrrole supercapacitors using cellulose nanocrystals and commonly used inorganic salts as dopants

“…CNCs were extracted from cotton wool using a modified Araki method (see supporting information) [29]. Through TEMPOoxidation, the surface hydroxyl groups of CNCs were converted into the carboxyl group as previously described [25,30]. PPy/ CNC-COO À -salt composite films were deposited in a threeelectrode system.…”

“…It suggests that KCl not only serves as a supporting electrolyte for the electropolymerization of PPy, but that it also contributes to the development of the 3D porous structure when combined with CNC-COO À . The relatively high cycling stability of PPy films is ascribed to the interconnected porous structure and the rigid and immobile CNC-COO À [25]. Cellulose nanocrystals (CNCs) are the ribbon-like crystalline sections of cellulose that are obtained from native cellulose by hydrolyzing the noncrystalline sections.…”

Green-in-green biohybrids as transient biotriboelectric nanogenerators

“… 45 The natural CNC has highly ordered crystalline structure, large specific surface area, unique morphological structure, good environmental compatibility, and strong hydrophilicity. As far, CNC has been applied in much advanced applications, such as supercapacitors, 46 batteries, 47 sensors, 48 , 49 and so forth. It is recognized as an attractive component for fabricating functional materials.…”
