“…The binding energy (BE) positions of individual components in different chemical environment were set according to the available literature . The C1s and N1 spectra for all the samples were fitted using three components, as reported in our previous publications . The C1s signal was fitted by a sum of three components corresponding to hydrocarbons ( C H x = 285.0 eV, used for the BE calibration), carbon bonded to nitrogen or oxygen ( C N/ C O/ C N ∼ 286.3 ± 0.1 eV) and carbon double bonded to oxygen (N C O/ C O ∼ 288 ± 0.1 eV) as demonstrated in Figure d.…”

“…Second, ammonia and allylamine are highly toxic flammable compounds and it is, therefore, preferred to avoid them. Recently, it was shown that the plasma polymerization of non‐toxic cyclopropylamine (CPA) led to the deposition of stable amine rich layers exhibiting 9.6 at.% of NH x environment combined with the thickness loss of 2% . These layers have been already used for the immobilization of biomolecules .…”

Plasma polymers with NHx groups were deposited from cyclopropylamine in low pressure radio frequency (RF) discharges. The amount of NHx decreased with increasing average power Pav, whereas the layer dissolution in water decreased and high Pav led to a slight film swelling. The C2C12 cells demonstrated very high adhesion to the layers regardless of the deposition conditions. Although the surface chemistry of amine‐rich layers should enhance the cell proliferation, the WST‐1 assay, and immunocytochemistry revealed lower cell proliferation and viability on the layers exhibiting above 18% of relative thickness loss in water. Promising results were obtained on the layers with better water stability and bearing 7–10% of NHx.

“…Primary amines were considered the most effective group to promote cell adhesion, due to their high reactivity and high stability in water. Manakhov et al (2015) have reported the results of adding the primary amine group onto nanofibers of polycaprolactone in the coating process, using CPA plasma polymerization. This study describes the amino factionalized TiO 2 NP S cross-linking on the CA-CNT composite nanofibers surface.…”

Photocatalytic degradation of organic dyes using composite nanofibers under UV irradiation

In this work, photocatalytic degradation of organic dyes such as methylene blue (MB) and indigo carmine (IC) have been studied by composite nanofibers systems containing cellulose acetate (CA), multiwall carbon nanotubes (CNT) and TiO 2 nanoparticles under UV light. The amino factionalized TiO 2 -NH 2 NPs cross-linked to the CA/CNT composite nanofibers works as a semiconductor catalyst. The morphology and crystallinity were characterized by scanning electron microscopy, transmission electron microscopy (TEM), X-ray diffraction, and Fourier transform infrared spectroscopy. It was also seen that many factors affected the photodegradation rate, mainly the pH of the solution and the dye concentration, temperature, etc. The study demonstrated that IC degrades at a higher rate than MB. The maximum photodegradation rate of both organic dyes was achieved at a pH 2. In comparison to other studies, this work achieved high photodegradation rate in lower time and using less power intensity.
