In situ in operando TOF-GISANS during morphological changes during the cyclic voltammetry cycles of a paper supercapacitor.

Cellulose nanofibrils (CNFs) are widely used due to their attractive properties such as low density, biocompatibility, lightweight, thermal stability, and good mechanical properties. These prerequisites make cellulose nanofibrils a promising precursor or nanoscaffold for the design of bio composites. To fulfil requirements of environmentally friendly devices, we need to fully understand the molecular architecture of cellulose nanofibrils in networks and within the presence of other nanomaterials. This knowledge would be beneficial to elucidate application of such networks for supercapacitors and battery applications. CNF provides perfect nanonetwork for electroactive materials (i.e PEDOT:PSS) in order to manufacture polymer/paper based green energy storage device electrodes. Hence, we want to study in situ and in operando the morphological changes in a paper-based supercapacitor.
