Preparation of conductive PTFE nanocomposite containing multiwalled carbon nanotube via latex heterocoagulation approach

Preparation of multiwall carbon nanotubes (MWCNTs) stabilised by highly branched hydrocarbon surfactants and dispersed in natural rubber latex nanocomposites

“…6(b) agree well with the literature with respect to the two characteristic peaks of MWCNTs at approximately 1,340 and 1,580 cm −1 ; these peaks correspond to the disorder band (D-band) and graphite band (G-band), respectively [44]. The intensity ratio of the D-and G-bands (I D /I G ) is commonly used to describe the disruption of the π-system in graphite sheets [6]. As evident in Fig.…”

“…The addition of 5 wt% of MWCNTs to NR-latex results in an increase in the electrical conductivity of three orders of magnitude to ∼10 −7 S cm −1 . This increase in electrical conductivity suggests the formation of a network of percolated MWCNTs in the polymer matrix that exceeds the percolation threshold [6,15].…”

“…They possess outstanding electrical, mechanical and thermal properties compared to conventional fillers, such as carbon black [5,6], and have therefore already attracted interest in various industries for possible applications in electronics [7] and medicine [8] and as flame retardants in polyurethane and polypropylene [9,10]. More recently, they have also been used in aerospace-based technology [11,12].…”

Improving the thermal properties of fluoroelastomer (Viton GF-600S) using acidic surface modified carbon nanotube

“…Huang et al [16] showed that the interfacial interaction between the single walled carbon nanotubes (with hydroxyl groups) and PVDF has an effect on inducing crystallinity. The thermal stability of the PTFE composites is also enhanced by the presence of CNT as reported by Park et al [18] . The temperatures recorded at maximum decomposition rate were affected by the type of surface modification of MWCNT.…”

“…The materials used were Viton GF-600S fluoroelastomer, FE; organic peroxide, Luperox 101 XL-45; acid surface modified carbon nanotube MCNT (TNMC8, -COOH Content:0.49wt%), carbon nanotube CNT (TNM8) both with an outside diameter > 50 nm, inside diameter:5-15nm, purity > 95%, and length [10][11][12][13][14][15][16][17][18][19][20] Mixing FE with additives was done using a laboratory scale two roll mill with a roll temperature of 48°C. FE in the above mentioned composition was supplied to the open roll.…”
