Conductivity-Dependent Strain Response of Carbon Nanotube Treated Bacterial Nanocellulose
نویسندگان
چکیده
is paper reports the strain sensitivity of �exible, electrically conductive, and nanostructured cellulose which was prepared by modi�cation of bacterial cellulose with double-walled carbon nanotubes (DWCNTs) and multiwalled carbon nanotubes (MWCNTs).e electrical conductivity depends on themodifying agent and its dispersion process.e conductivity of the samples obtained from bacterial cellulose (�NC) pellicles modi�ed with DWCNT was in the range from 0.034 S⋅cm to 0.39 S⋅cm, and for �NC pellicles modi�ed with MWCNTs it was from 0.12 S⋅cm to 1.6 S⋅cm. e strain-induced electromechanical response, resistance versus strain, was monitored during the application of tensile force in order to study the sensitivity of the modi�ed nanocellulose. A maximum gauge factor of 252 was found from the highest conductive sample treated by MWCNT. It has been observed that the sensitivity of the sample depends on the conductivity of the modi�ed cellulose.

Mechanically excellent native cellulose nanofibers that are cleaved from plant cell walls have been modified by functionalized few-walled carbon nanotubes for hybrid nanofiber/nanotube aerogels. They show elastic mechanical behavior in combination with reversible electrical response under compression allowing responsive conductivity and pressure sensing. The concept combines wide availability o...
