“…1. In the spectrum of pristine PES powder [16], the characteristic absorption bands at 1323 and 1300 cm −1 due to asymmetric stretching vibration and at 1151 cm −1 the symmetric stretching of sulfone group were observed. The aromatic skeletal vibrations at 1577 and stretching vibration at 1485 cm −1 , phenylene ether stretching vibration at 1240 cm −1 , ring vibration of p-substituted phenyl ethers at 1010 cm −1 , outof-plane C-H deformation characteristic of p-substituted phenyl at 835 cm −1 , C-S stretching vibration at 719 cm −1 were also observed.…”

“…13,14 Poly(ether sulfone) (PES) is a high-performance amorphous thermoplastic with high glass transition temperatures (T g ¼ 225 C), outstanding high temperature stability, and excellent mechanical properties. 15 Moreover, PES exhibiting good solubility in some organic solvents has similar chemical structure to PEEK polymer, and shows good miscibility as well as chemical compatibility with PEEK at very low PES content. 16 In this work, it is chosen as a functionalizing agent of CNTs, expecting that its affinity with the filler and the matrix could lead to better dispersion of the CNTs throughout the matrix and strong reinforcement effect.…”

Multiwalled carbon nanotubes (MWCNTs) were functionalized with aminated poly(ether sulfone) (PES) through the amidation reaction. Characterizations by Fourier transform infrared spectroscopy and X-ray diffraction corroborated the success of grafting reaction. Raman spectra reveal that no further damage occurred after the anchoring of PES to the carboxylated MWCNTs. Transmission electron microscopy shows that PES functionalization resulted in better dispersion of MWCNTs than acid oxidation. Poly(ether ether ketone) (PEEK)/MWCNTs functionalized with PES (PES-MWCNTs) nanocomposites were fabricated by solution-mixing and compression-molding techniques. Thermogravimetric analysis indicates that PES-MWCNTs/PEEK nanocomposites have the highest degradation temperature and thermal stability. Furthermore, noticeable increases in the crystallization and melting temperature as well as in the degree of crystallinity were found from differential scanning calorimetry thermograms, attributed to the strong heterogeneous nucleating role of PES-MWCNTs. Tensile test presents that the attachment of PES to the surface of MWCNTs exceptionally improved the tensile strength and Young's modulus, and obtained moderate elongation at break. Impact toughness test and dynamic mechanical analysis show that the addition of PES-MWCNTs greatly enhanced the toughness and storage modulus of PEEK, respectively. These results are attributed to improved dispersion of PES-MWCNTs and strong interfacial adhesion to matrix, which is evidenced by scanning electron microscopy.
