Biobased Electronics: Tunable Dielectric and Piezoelectric Cellulose Nanocrystal-Protein Films.

ABSTRACT: Cellulose has been a go-to material for its dielectric properties from the onset of capacitor development. The demand for an energy storage solution continues to grow, but the supply remains limited and relies too often on fossil and mined materials. This work proposes a fully sustainable and green method with which to produce dielectric thin films made of renewable and degradable materials. Cellulose nanocrystals (CNC) made an excellent matrix for the dispersion of proteins and the fabrication of robust transparent thin films with enhanced dielectric permittivity. A range of proteins sources, additives and concentrations allowed for us to control the dielectric permittivity from ε_r = 4 to 50. The proteins screened came from animal and plant sources. The films were formed
