“…The probable reason is higher MWCNT volume fraction and compactness of filtered MWCNT network with respect to powdery CNT layer investigated in [5]. The best description of the data in Fig.15 is obtained by the series heterogeneous model when the resistance is described as the sum of metallic (MWCNT are regarded as metallic conductors) and barrier portions of conduction path [21][22][23] …”

Abstract.A network of entangled multiwall carbon nanotubes and the composite consisting of filter-supported multiwall carbon nanotube network are conductors whose conductivity is sensitive to compressive stress both in the course of monotonic stress growth and when loading/unloading cycles are imposed. The testing has shown as much as 100% network conductivity increase at the maximum applied stress. The entangled carbon nanotube networks are prepared by vacuum filtration method and peeled off from the filter. The carbon nanotubes are used in pristine condition or chemically functionalized. The filtersupported entangled networks are prepared by the nanotube dispersion filtration through a non-woven flexible polystyrene filter. The nanotubes infiltrate partly into the filter surface pores and link the accumulated filtrate layer with the filtering mat. The filter-support increases nanotube network mechanical integrity, the composite tensile ultimate strength and affects favorably the composite electrical resistance. Other obvious effect of the supporting polymer is reduction of the resistance temperature dependence. Moreover, the conductivity of carbon nanotube networks manifests also organic vapor dependence. The dependence is reversible, reproducible, selective as well as influenced by nanotube oxidation.

“…Moreover, for SWCNTs with tangled regions the nonmetallic term can be described by proposed for variable range hopping conductivity Mott's law (1), indicating localization of charge carriers and hopping transport instead of fluctuation-induced tunneling (Kaiser et al, 1999). We assume that in our samples the localization effects and the resulting hopping transport can be essential only at very low temperatures where the rapid rise of the resistance is observed as the temperature decrease.…”

“…The behavior of relatively sparse transparent networks is most relevant for transparent contacts [70][71][72]. These works have identified several factors including network density [70,73], interactions between tubes or bundles [70,73], bundle length [71], and doping [41] as having a strong influence on network conductivity.…”
