Improving the antistatic ability of polypropylene fibers by inner antistatic agent filled with carbon nanotubes

Improvement in electrical, thermal and mechanical properties of epoxy by filling carbon nanotube

“…Different polymer/CNT nanocomposites have been synthesized by incorporating CNTs into various polymer matrices, such as polyamides [12], polyimides [13][14][15], epoxy [16], polyurethane [17,18] and polypropylene [19][20][21]. Previous results indicated that the addition of small amounts of CNT (<1 wt%) to a matrix system can increase electric, thermal and mechanical properties without compromising the weight or processability of the composite.…”

Epoxy-based Carbon Nanotubes Reinforced Composites

“…These polymer-based nanocomposites are expected to derive high properties at low filler volume fractions due to the high aspect ratio and high surface area to volume ratio of the nano-sized particles [Zhou et al, 2008;Hu et al, 2008;Santos et al, 2008]. In recent years, different types of polymer composites have been synthesized by incorporating CNTs into various polymer matrices such as polyamides [Zhao et al, 2005], polyimides [Cai et al, 2004;Ogasawara et al, 2004], epoxy [Winey et al, 2007;Hu et al, 2008;Liao et al, 2004], polyurethane [Koerner et al, 2005 ;Kuan et al, 2005], polypropylene [Seo et al, 2004;Li et al, 2004;Seo et al, 2005], polyethylene [Haggenmueller et al, 2006], polyethylene oxide [San et al, 2001], poly(vinyl alcohol) , poly(methyl methacrylate) [Jin et al, 2001], polycarbonate [Postscke et al, 2003], poly(butylene succinate) [Sinha Ray & Okomoto, 2003], polylactide [Chiu et al, 2008], polyaniline [Zing et al, 2008], polypyrrole [Sahoo et al, 2007], poly (N-vinylcarbazole) [Maity et al, 2007;Maity & Sinha Ray, 2008a ;Maity & Sinha Ray, 2008b], poly(ethylene 2, 6-naphthalate) , poly(butylenes terephthalate) [Garcia-Gutierrez et al, 2008], poly(p-phenylene benzobisoxazole) [Kumar et al, 2002], glycopolymer and others [Fragneaud et al, 2007]. However, the potential of using CNTs as reinforcements has not been realized mainly because of the difficulties in processing and the limitation on load transfer.…”

High performance PA6/CNTs nanohybrid fibers prepared in the melt

“…Undoubtedly, the most attractive method to produce electrically conductive polymer-based materials is adding appropriate fillers which are able to provide the desired electrical properties [1,2,4]. The effectiveness of this operation lies in a good dispersion of the filler with the primary goal to get the highest electrical conductivity with the lowest filler content.…”

“…Using nanoscaled fillers offers the possibility to achieve the aim by adding small amounts (even less than 1 wt.%) due to their high specific surface. Among these nanofillers, CNTs are interesting because of their unique combination of low density, large aspect ratio, good dimensional stability, high mechanical performance and electrical conductivity [1,2,4,5]. The ways to add CNTs into polymer matrices refer to two different inclusion approaches: in solution and in the melt.…”

“…In particular, the primary aim is to obtain new materials bearing the flexibility and the low density typical of polymers with the electrical conductivity typical of metals or semiconductors in the view of applications in sensors, electronics, electromagnetic shields or antistatic devices [1,2].…”
