“…Some of these include mixing conductive materials and pulp fibers and subjecting them to the traditional papermaking process (Oya and Ogino 2008;Agarwal et al 2009;Anderson et al 2010;Jabbour et al 2012); coating the papers with conductive fillers (Hu et al 2009;Tang et al 2014); and in-situ polymerization and adsorption of conductive polymers onto pulp fibers before using them in paper making (Li et al 2010a;Youssef et al 2012).…”

Conductive papers were prepared via surface coating with graphite or carbon black using either carboxylated styrene butadiene latex or starch as the binder. It is of practical interest to determine the percolation threshold for the coated paper product made using a binary system consisting of conductive filler and binder. In this study, the electroconductivity threshold of various conductive papers was determined based on experimental data according to the percolation law. Results showed that the conductivity of coated, conductive paper is a function of the volume fraction of conductive filler, which can be described well by the percolation theory. The percolation thresholds of graphite/latex, graphite/starch, carbon black/latex, and carbon black/starch coatings were 17.66, 12.36, 11.71, and 8.69 vol.%, respectively. At concentrations higher than the percolation threshold, the conductivity of conductive paper using graphite as the conductive filler was much higher than that achieved using carbon black at a similar volume fraction. The present paper has significant practical implications for conductive paper technology using graphite filler based on surface coating technology.

Exploiting high quality PEDOT:PSS–SWNT composite formulations for wet-spinning multifunctional fibers

In order to exploit the inherent properties of carbon nanotubes (CNT) in any polymer composite, systematic control of carbon nanotube loading and protocols that mitigate against CNT bundling are required. If such composites are to be rendered in fiber form via wet-spinning, then CNT bundling during the coagulation process must also be avoided. Here we have achieved this by utilizing highly exfoliated single walled carbon nanotubes (SWNT) and poly(3,4-ethylenedioxythiophene):poly(styrenesulfonicacid) (PEDOT:PSS) to obtain wet-spinnable composite formulations at various nanotube volume fractions (V f ). The addition of only 0.02 V f of aggregate-free and individually dispersed SWNT resulted in a significant enhancement of modulus, tensile strength, electrical conductivity and two cell electrode specific capacitance of PEDOT:PSS-SWNT composite fibers to 5.2 GPa, 200 MPa, 450 S cm −1 and 59 F g −1 by the rate of dY/dV f = 89 GPa, dσ/dV f = 3.2 GPa, dS/dV f = 13300 S cm −1 and 6 folds, respectively.

“…Anderson et al reported that SWCNT suspensions were stabilized by carboxymethyl cellulose (CMC) and a positively charged additive, alum, acted as a bridge between two anionic surfaces (cellulose fiber-fiber, fiber-CMC, CMC-CMC) [26]. These methods also are effective for adsorbing CNTs on cellulose surfaces.…”
