MWCNT reinforced Polyamide-6,6 films: preparation, characterization and properties

Water sorption of PA12/PA6/MWCNT composites with a segregated conductive network: structure–property relationships

“…The authors concluded that the free volume increased in the nanocomposites due to loosened molecular packing of the polymer chains, in agreement with an observed decrease in Tg value. However, in another study, Sengupta [20] observed that water absorption decreases remarkably with increasing nanotube concentration in PA66/MWCNT films. Notwithstanding the research reported, water diffusion mechanisms are still controversial.…”

Facile synthesis and magnetic study of Ni@polyamide 66 coaxial nanotube arrays

“…Two α phases which were designated as α1 (about 2θ¼ 20.4°) and α2 (about 2θ¼ 24.1°), separately. Two γ phases which were designated as γ1 (about 2θ¼ 21.8°) and γ2 (about 2θ ¼13.6°), separately [22][23][24]. However, only γ crystalline phase exists in the PA66 nanotubes at room temperature as revealed by the presence of the γ peak at 22.2°.…”

Dispersibility and chemical bonds between multi-walled carbon nanotubes and poly(ether ether ketone) in nanocomposite fibers

“…On the other hand, the temperature of melt-spun up to 395 C, makes it probable to create chemical bonds between MWNTeCOOH and matrix [15,16]. Sengupta et al prepared composite films of nylon 6,6 and MWNTs by a combination of solution casting followed by compression molding at 280 C [39]. Both pristine and MWNTeCOOH were used.…”
