“…Thus, its coupling with wood derivatives intends to be a solution to overcome these problems. Pyrrole (Py) can actually be polymerised onto fibres, [11][12][13][14] paper, [15] cakes [16,17] and films, [18] thus obtaining wood derivatives/PPy free-standing flexible substrates. In these works, PPy was generally chemically synthesised by subsequently impregnating/incorporating the reactants (monomer, additive and oxidant), or via Py condensation onto the substrate from vapour phase (PPy dissolution was not necessary in order to obtain handling substrates).…”

PPy was synthesised by oxidative chemical polymerisation using xylan, CMC and NFC as additives. Conducting nanocomposite films were cast from aqueous slurries using doped PPy particles, CMC and NFC as the conducting and reinforcing phase, respectively. NFC‐based composites had higher conductivity and lower mechanical properties than CMC‐based homologues. SEM analysis showed that in PPy/NFC composites, PPy and NFC were arranged in two entangled networks, whereas, in PPy/NFC composites, CMC formed a continuous matrix around PPy particles, thus limiting conductivity. Mechanical properties of nanocomposite films were interpreted as reflecting the presence of different structures when using NFC or CMC as reinforcing phase.magnified image

“…Polypyrrole (PPy) has attracted increasing attention becasue of the low cost, ease of synthesis, environmental friendliness, high oxygen resistance and electroconductivity (Huang et al 2006;Beneventi et al 2006;Chen and Qian 2007). The micromorphology, conductivity and stability of PPy are greatly dependent on the characteristics of the dopant.…”

Polypyrrole/cellulose fiber-conductive composites were chemically synthesized in situ by using, for the first time, cationic polyacrylate copolymer as dopant and FeCl 3 as oxidant. The impacts of dopant charge density on the adsorption of the dopant on cellulose fiber, microstructure, tensile strength, conductivity and stability were investigated. In addition, the elemental composition, distribution and doping state of the polypyrrole in conductive fiber were determined by elemental analysis and X-ray photoelectron spectroscopy. Compared with anthraquinone-2-sulfonic acid sodium salt, cationic polyacrylate copolymer was a more effective dopant in increasing the conductivity and conductivity stability of conductive paper. The decay of mechanical properties was also weakened. The surface resistivity decreased from 4.6 to 0.3 KX square -1 with increasing dopant charge density from 0.525 to 0.820 lmol g -1 and then increased with a further increase in the dopant charge density. It was also found that the polypyrrole retention in conductive fiber reached the maximum when the charge density of the dopant was 0.820 lmol g -1 . When the conductive fiber was doped with high-charged dopant, polypyrrole was easier to enter into the fiber lumen, and bipoloran charge carriers were more easily formed. With respect to the conductive fibers prepared with dopant of 0.820 and 0.525 lmol g -1 charge density, the total content of polaron and bipolaron in the former conductive fiber was higher than the content of polaron in the latter conductive fiber. In addition, uniform and denser nanofibrous PPy can be formed by controlling the dopant charge density.

“…Some mixtures of conducting polymers with cellulose are known; especially composites of cellulose with polypyrrole are described in literature (Beneventi et al 2006;Jungbauer and Klaassen 2006). Nevertheless in these materials the fibrous structure of cellulose is used in the carrier part and the conducting component is situated just at the surface of the cellulosic matrix, forming a quasi coating rather than a real composite mixture.…”

Conjugated polymers gain growing importance as conductive materials in industrial applications in various fields of electronic devices. Cellulose with its extraordinary supramolecular structure and material properties can help to awake the possibilities for conducting polymers in interplay of the two materials. The ability of additional derivatization, the stiff and oriented molecular structure and the inherent strength, stability and film-forming properties give cellulose a complementary role to the brittle conjugated polymers, cellulose imparting the features of a stable and robust carrier component. To go forward this way, making a composite out of cellulose and conducting polymers is a prerequisite. Different strategies to form composite materials of non-derivatized cellulose and conductive organic polymers were tested. Significant differences between various mixing strategies as well as between the conducting polymers polyaniline (PAni), polypyrrole (PPy), and polythiophen (PTh) were observed. In situ synthesis of the conducting polymers in cellulose solutions and microcellulose dispersions as well as blending of pre-synthesized conducting polymers in these cellulose systems were tested. Unexpectedly, not homogenous mixtures showed best results in respect to film formation and conductivity, but composites formed by heterogeneous mixtures of the conducting polymers within a cellulose gel. Best results were obtained with finely dispersed PAni. The results support development studies towards circuitry and photo-current systems based on cellulose carriers.
