One step in situ synthesis of Ag/AgCl nanoparticles in a cellulose nanofiber matrix for the development of energy storage paper

In the present work, we prepare Cellulose Nanofibers Films (CNFs) incorporating silver nanostructures (Ag/AgCl nanocubes) in a ratio of 1-20 wt% to the organic matrix. We found that with the increase of Ag wt%, a raise in crystalline species corresponding to Ag/AgCl was observed. The diffraction pattern in 2 circle minus = 44.7 degrees planes belonging to Ag (2 0 0) shifts to 2 circle minus= 45.45 degrees with planes AgCl (2 2 0), due to the increase of Ag. Furthermore, we describe that incrementation in silver concentration aid in fibers gaining a higher arrangement. Scanning Electron Microscopy (SEM) images showed cubic structures formed by smaller cubic nanostructures. Electrochemical Impedance tests determined electrical resistance of the films, obtaining values of 551 Omega cm(2), 62.6 Omega cm(2), 3.78 Omega cm(2), 7.9 Omega cm(2), and 15.8 Omega cm(2) for concentrations of 1 wt%, 5 wt%, 10 wt%, 15 wt%, and 20 wt% respectively; in addition to obtaining the CPE from films, demonstrating that they possess electrical conduction and energy storage capabilities.
