Nanocomposites based on graphene nanoplatelets (GNP) were developed using recycled cellulose acetate from cigarette filters as the polymer matrix. Electrical conductivity measurements showed significant improvement with increasing GNP content, peaking at the saturation of the electrical network. The electromechanical performance of the sensors demonstrated a gauge factor (GF) near 20 at 3 wt% GNP content in the 0-2% strain range due to the tunneling effect. The new matrix ensures sensor sustainability and stability through cyclic testing.

Abstract
Nanocomposites based on graphene nanoplatelets (GNP) were developed using recycled cellulose acetate from cigarette filters as the polymer matrix. Electrical conductivity measurements showed significant improvement with increasing GNP content, peaking at the saturation of the electrical network. The electromechanical performance of the sensors demonstrated a gauge factor (GF) near 20 at 3 wt% GNP content in the 0-2% strain range due to the tunneling effect. The new matrix ensures sensor sustainability and stability through cyclic testing.File in questo prodotto:
