Application of Nanocellulose in Energy Materials and Devices

Progress of silver-loaded cellulose composite antimicrobial materials

“…However, drying and heat treatment may lead to changes in the properties of the cellulose matrix. Hao Chen Silver nanoparticles were obtained by reducing silver nitrate using the aldehyde group on DANC, and then crosslinked with the free amino group on CS by Schiff base reaction, an elastic brown gel can be obtained that is nanocellulose-silver-chitosan composite gel [29]. Different ratios of gel complexes can be prepared by changing the dosage ratio of nanocellulose and chitosan.…”

Sustainable and Printable Nanocellulose-Based Ionogels as Gel Polymer Electrolytes for Supercapacitors

“…NC can be classified into the following categories depending on the source, preparation methods and fiber morphology: (1) cellulose nanofibers (CNF), which refers to the nanoscale cellulose fibrils obtained by fibrillating cellulose under the action of high pressure or mechanical forces, (2) cellulose nanocrystals (CNC) obtained by acid hydrolysis conditions to form nano-sized, rod shaped particles with high crystallinity, and (3) bacterial nanocellulose (BC) with a high aspect ratio obtained by a microbial fermentation process [12,13]. Compared with other biomass-derived green materials, such as lignin, chitin, etc., NC shows great advantages in the field of ESSs [14][15][16][17][18][19][20]: versatile surface modification via functionalization of its hydroxyl groups that allow the integration of other active materials; great thermal stability and extraordinary mechanical properties that can improve the safety properties of the ESSs, through formation of the previous mentioned gel polymer electrolytes (GPEs) [20].…”
