Sensing application of nanocellulose modified with double-walled carbon nanotube and graphitized carbon nanopowder
Paper in proceedings, 2011

Electrically conductive nanocellulose films were prepared by immersion in well dispersed solutions of double walled carbon nanotubes or graphitized nanopow¬der. These solutions were prepared by using the surfactant cetyltrimethylammonium bromide (CTAB) under heating and stirring conditions which were followed by a short time sonication process. Electrospun cellulose and bacterial cellulose were used as a backbone of these films. Controllable modification of cellulose with conductive agents was performed by treatment with their dispersions for 24 – 72 hours. Electrical conductivities of the resulting films are from 0,009 S cm-1 to 0,395 S cm-1 which is higher or comparable to previously reported results. Some methods have been employed to study the electrical conductivity behavior of samples. The electrical conductance of the films displays a high sensitivity to strain when tensile stress is applied.
