Sensing application of nanocellulose modified with double-walled carbon nanotube and graphitized carbon nanopowder
Paper i proceeding, 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.
