Magnetic-field-assisted electrospinning highly aligned composite nanofibers containing well-aligned multiwalled carbon nanotubes

Conductive polymer nanocomposites (CPNCs) have gained a lot of attention by the researchers, in recent times, due to their diverse technological applications in different domains. This paper discusses the additive manufacturing of conductive polymer nanocomposite. Maghemite-Multiwalled carbon nanotubes were synthesized, and later dispersed in an acrylate resin, followed by curing with UV DLP 3D printer, under the presence of external magnetic field. Maghemite-Multiwalled carbon nanotubes showed superior magnetic properties, when compared to Multiwalled carbon nanotubes and lead to improvements in preferential alignment of filler material in the polymer matrix. The initial experimental results show preferential alignment of Maghemite-Multiwalled carbon nanotubes in the polymer matrix under the influence of external uniform magnetic field, at an intensity of 120 Gauss.

Discharge Method

Multiwalled Carbon Nanotubes (MWCNTs) have been synthesized using a low cost arc discharge method without using metal catalyst and vacuum devices. Effect of magnetic field on the synthesis of MWCNTs and their purity has been scrutinized. A magnetic field of 310 gauss has been found to give better purity of carbon nanotubes as confirmed by Raman spectroscopy. However, the removal of amorphous carbon from the surface of so prepared multiwalled carbon nanotubes has been achieved by different oxidizing conditions. It has been observed that the maximum removal of amorphous carbon found by using the strong oxidizing agent HNO3/H2O2. This strong oxidizing agent HNO3/H2O2 removes most of the carbonaceous impurities leading to thermal stability of carbon nanotubes suggested by thermo gravimetric analysis. X-ray diffraction show the formation of carbon nanotubes having a peak indexed at (002) as the fingerprint for multiwalled carbon nanotubes. Fourier Transform Infrared (FTIR) spectra confirmed the formation of the multiwalled carbon nanotubes showing a characteristic stretching band at 1615 cm-1 corresponding to the C=C bonds of tubular carbon. Raman spectroscopy revealed invaluable insights into the purification of nanotubes. G-band (1577 cm-1) corresponds to the confirmation of MWCNTs. Defect induced D-band (1355 cm-1) has been minimized after purifying CNTs with HNO3/H2O2 for 24 hrs. Transmission Electron microscopic (TEM) studies indicate the formation of CNTs with controlled alignment having diameter in the range 2-8 nm.
