“…The E 0 for the composites containing 1.2 wt % PL-MWCNT shows an improvement of~39% at 30 C as compared to the pure Nylon 12. This substantial improvement in storage modulus attributes for fine dispersion of the functionalized CNTs within the polymer matrix, well compatibility and strong interfacial interactions between the filler and polymer matrix, and the high performance effect of the MWCNT fillers [34].…”

“…The spectrum is fitted to three peaks positioned at 285.01, 287.83, and 288.98 eV. The main peak at 285.01 eV identified as C-C bonding present in the C 60 , whereas the other two peaks at 287.83 eVand 288.98 eV were attributed to the C=O and -O-C = O bonding, respectively [44]. Figure 11 shows the O1s core-level spectrum.…”

Cu-C 60 nanocomposite thin films are synthesized by co-deposition restive heating method on glass, silicon, and TEM grid substrates. Rutherford backscattering spectroscopy (RBS) analysis is used for determining the composition of Cu and thickness of thin film which one found to be ∼13 at% and ∼28 nm, respectively. The deposited thin films are irradiated with 100 keV Ag ion at different fluences ranging from 1 × 10 14 to 3 × 10 16 ions/cm 2 . Being of low energy, Ag ions got implanted in SiO 2 substrate up to a depth of 30-40 nm that results in wide surface plasmon resonance (SPR) band in combination with SPR of Cu nanoparticles. UVvisible absorption spectroscopy demonstrates the SPR peak arises due to copper nanoparticles embedded in fullerene C 60 matrix on irradiation of nanocomposite thin film and its variation under implantation of Ag nanoparticles in SiO 2 substrate. Structural modifications due to ion irradiation are analyzed by Raman and transmission electron microscopy (TEM). Raman spectroscopy study reveals the transformation of fullerene C 60 into amorphous carbon (a-C) with increasing fluence. Variation in particle distribution is observed under TEM. The average particle sizes are found to be ∼4 ± 0.7 and ∼6 ± 0.4 nm for pristine and 100 keV Ag ion-irradiated thin films, respectively. Atomic force microscopy (AFM) confirms the increase in grain size with increase in roughness of nanocomposite thin films under the effect of implantation. Xray photoelectron spectroscopy (XPS) confirms the presence of Cu and C from their chemical bonding in Cu-C 60 nanocomposite thin films.

“…The spectrum of SW_HNO 3 :H2SO 4 is different from that ones of other samples. It contains the additional peak at 288.7 eV assigned COOH group, while the shake‐up peak is absent. A low‐energy shift of the C 1 s spectrum of SW_HNO 3 :H 2 SO 4 sample by 0.3 eV as compared to other spectra could be due to the p ‐type doping effect in agreement with optical absorption data (Figure b).…”

A detailed analysis of TUBALL single‐walled carbon nanotubes (SWCNTs) after two‐step purification involving acid purification treatment with concentrated HCl, HNO3, H2SO4 and solution of HNO3:H2SO4 followed by magnetic processing is presented. The purity degree from iron higher than 99% is achieved, and the yield obtained by the above process is about 75 wt.%. Such high purity of the resultant sample is achieved by removing of the external iron nanoparticles by acid treatment and following extraction of nanotubes containing encapsulated nanoparticles under applied magnetic field. A comprehensive characterization of SWCNTs by Raman, optical absorption, and X‐ray photoelectron spectroscopies reveals purification‐induced changes in the integrity, composition, and electronic properties of SWCNT.
