CNTs/ UHMWPE composites with a two-dimensional conductive network

Lightweight conductive graphene/thermoplastic polyurethane foams with ultrahigh compressibility for piezoresistive sensing

“…Due to the high conductivity of graphene, it could reduce the percolation threshold of CPCs significantly, avoiding the sacrifice of mechanical properties of CPCs. 37,38 On the other hand, the large specific surface area and good flexibility of graphene will also lead to an extraordinary conductive network and dispersion morphology in CPCs. To explore its application, the threedimensional architectures of graphene or its derivatives (such as graphene aerogel/polydimethylsiloxane (PDMS), 39 graphene foam (GF), 40 GF/PDMS, 41,42 etc.)…”

“…It is known that values of t around 1.3 and 2.0 correspond to two and threedimensions, respectively. 37 A percolation threshold of 0.061 vol% was obtained from the fitting result. In addition, the universal critical exponent t was estimated to be 0.42 (the inset of Fig.…”

Carbon nanotubes induced nonisothermal crystallization of ultrahigh molecular weight polyethylene with reduced chain entanglements

“…CNTs possess unique mechanical, thermal, and electrical properties [2][3][4]. These unique properties and high aspect ratio make CNTs a preferred candidate to be used as fillers in manufacturing high-performance and in particular conductive composites [5][6][7][8][9].…”

Carbon Nanotubes as Conductive Filler in Segregated Polymer Composites - Electrical Properties

“…The comparison of CB/UHMWPE and MWCNT/UHMWPE segregated systems has shown that the values of percolation thresholds were less than 0.5 % in both of cases (Hao et al, 2008). Investigation of conductivity of the MWCNT/UHMWPE composites (Gao et al, 2008) has revealed two-dimensional character of the MWCNT structure and low value of percolation threshold (φ c =0.072 %). In this study the value of critical parameter t in the scaling relation that describes the conductivity above φ c…”
