Ultra-thin flexible paper of BNNT–CNF/ZnO ternary nanostructure for enhanced solid-state supercapacitor and piezoelectric response

Nanosized ZnO particles have been synthesized on cellulose nanofiber and boron nitride nanotube surfaces via a hydrothermal route to give a ternary nanostructure and explored flexible papers for the electrochemical and piezoelectric performance.
