| Resumo: | Coming from renewable and sustainable raw materials, nanocelluloses are rapidly emerging as one of the most promising future materials. Recently, the use of nanocellulose nanocomposites in flexible electrodes, biosensors or supercapacitors it is been studied. The main objective of this thesis is to produce conductive nanopapers from cellulose nanofibers (CNF) or bacterial cellulose (BC) and tree different conductive materials: polypyrrole (PPy), poly(3,4-ethylenedioxythiophene : polystyrene sulfonate (PEDOT:PSS) and multi-walled carbon nanotubes (MWCNT). The structure and morphology of nanocomposites were studied, as well as their thermal, mechanical, and electrical conductivity properties. The results revealed the semiconductor or conductor character of the obtained nanocomposites, with specific capacitances up to 300 F g-1 for CNF-PPy and CNF-PEDOT:PSS-PPy nanocomposites. This work demonstrates the feasibility of using cellulose nanofibers in the field of green and flexible electronics, biosensors, and energy storage devices |
