Nanocomposite conjugated polymer

The electrical conductance of carbon nanotubes is sensitive to the chemical environment of the tubes. A large difference in the electrical conductance is observed for the carbon nanotubes in the presence of air and oxygen atmosphere. " " It is possible to tune the electrical conductance of carbon nantubes reversibly using adsorbent gas molecules. The carbon nanotubes were also used to increase the conductance of a conjugated polymer for the development of electroluminescence polymer-nanocomposites. " ... 

The number of organic materials is of great interest in microelectronic and optoelectronic devices [1], In particular, the conjugated polymers, such as ladder-type methyl substituted poly-para-phenylene (Me-LPPP) and poly[2-methoxy-5-(2-ethylhexyloxy)-l,4-phenylene vinilene] (MEH-PPV) and their nanocomposites, have been widely investigated due to their perspectives in light-emitting diodes and solar cells [2—4].

Van den Ber et al. [166] has prepared nanocomposites of semi conducting polymers reinforced with tunicate cellulose whiskers with a typical diameter or around 20 nm. The results showed that the nanocomposites synergistically combine the electronic characteristic of the conjugated polymers with the improved mechanical properties of the cellulose scaffold. Other studies suggest that cellulose whisker can be used for electrical applications such as the creation of circuitry in a special kind of smart paper [167].
