“…The nanotubes were purified to produce a carbon purity >95% and a metal oxide impurity <5% as it results by thermogravimetric analysis (TGA). The specific surface area determined with the BET method is around 250-300 m 2 /g [17]. Neat sPS sample and the composite materials containing different concentration of multi-walled carbon nanotubes (1, 3, 6 and 9 wt%) were prepared using a laboratory-scale conical twin-screw extruder 'Micro-Coumpounder' by ThermoHaake (Germany).…”

“…Polymorphic state has been only altered in the presence of miscible polymers, such as poly(2,6-dimethyl-p-phenylene oxide) [9] or atactic polystyrene, which reduced in sPS blends the α form crystallinity, increasing the β form [10,11]. Recent experimental investigations are demonstrating the potential of carbon nanotubes as small-volume fraction reinforcements in polymer matrix systems [12][13][14][15][16][17]. Carbon nanotubes are also known to impart profound changes to the crystallization behavior of semicrystalline polymers.…”

Abstract. Syndiotactic polystyrene (sPS) samples were quenched at low temperature (0°C) in the presence of Multi-Walled Carbon Nanotubes (MWCNT) at different concentrations. The influence of carbon nanotubes on the structure and physical properties of sPS composites was investigated by SEM, X-ray diffractograms, DSC (Differential Scanning Calorimetry), and Dynamic Mechanical Analysis (DMA). A good dispersion of the carbon nanotubes in the sPS matrix was found, at least for the low MWCNT concentration, whereas opposite effects were noticed on Tg and elastic modulus, depending on concentration. The pristine sPS sample was almost amorphous at 0°C, whereas in the filled samples the crystallinity increased on increasing the MWCNT concentration, indicating a strong nucleation effect of the nanotubes. Interestingly, in spite of the low temperature, the β crystallinity was induced and this crystalline form increases on increasing the carbon nanotube concentration, being dominant (68% of the total crystallinity) already at 3 wt% of MWCNT concentration.

“…Separately synthesized carbon nanotubes (CNT), the sizes of which do not exceed 100 nm are commonly used as modifiers. CNTs have an extremely high elastic modulus of about 1 TPa, which is comparable to diamond (1.2 TPa) and demonstrates a strength of 10-100 times higher than that of structural steels [2]. In addition, polymer nanocomposites have an electrical conductivity of 10 5 -10 7 S/m [3] and can transform a dielectric polymer into a conductive composite.…”

“…1 CNTs have high elastic modulus about 1 TPa comparable to that of diamond (1.2 TPa) and strength of 100 times that of steel. [1][2][3] And they have relatively high electrical conductivity (10 5 -10 7 S/m). 4 These superior properties of the CNTs in combination with their nanoscale structures, low mass density, and high aspect ratio (typically >1000), make them excellent candidates for a number of applications such as electromagnetic shielding devices, field emission display, gas sensors, hydrogen storage, and polymer composites.…”

Multiwall carbon nanotubes (MWCNTs) were modified with a water soluble polymer, poly(vinyl alcohol), PVA, using a simple ultrasonic wave in water. Under the irradiation of ultrasound, PVA chains were severed as macroradicals and instantly grafted onto the surface of MWCNTs due to the radical scavenging effect of MWCNTs. To control the grafting PVA onto MWCNTs, the ultrasonication power and irradiation time were changed from 300 to 500 W and from 10 to 50 min, respectively. The grafted PVA onto MWCNTs was confirmed by FTIR, TGA, SEM, and TEM. Dispersion stability of the modified MWCNTs was monitored by Turbiscan. The amount of grafted PVA on MWCNTs increased with the increase in the sonication power and irradiation time. The grafted PVA on MWCNTs induced the improved dispersion stability of the modified MWCNTs in water. These findings exhibit that ultrasound can be readily used for the grafting polymer chains on MWCNTs.
