“…The binding energies (BE) of C 1s, O 1s, and N 1s were 285.0, 532.1, and 399.1 eV, respectively, and there are consistent with those previously reported in the literature. 27,39,45 In the spectra of Fig. 4, the peak corresponding to N 1s (399.1 eV) was evidenced, and its noted with more intensity in the treatment with DTA than in the treatment with EDA because DTA is a triamine and EDA is a diamine, so the amount of nitrogen species, it will always be higher for DTA treatments.…”

BACKGROUND Poly(ethylene terephthalate) (PET) waste films were treated by cold plasma aminolysis to graft primary amino groups (‐NH2) and the surface biocompatibility of the polymer was improved. Aminated PET waste films were obtained by applying radiofrequency (RF) plasma treatment of either diethylenetriamine (DTA) or ethylenediamine (EDA). Aminolysis was applied during 5, 10 and 15 min at plasma power levels of 150, 175 and 200 W. RESULTS Water contact angle study revealed that the surface of PET waste films became more hydrophilic after plasma treatment, the contact angles decreased as exposure time or plasma power increased. Also, X‐ray photoelectron spectroscopy (XPS) and Fourier transform infrared spectroscopy (FTIR) detected signals related to ‐NH2 functional groups at the surface of treated PET films. In relation to the biocompatibility properties of the aminated PET waste films, most of them, do not present hemolytic problems, but those treated with DTA at 150 W for 10 min (PET‐DTA/150 W‐10 min) showed the least hemolytic effect. On the other hand, it was proved that plasma treatment of PET waste films conferred a sterilization effect against Pseudomonas aeruginosa bacteria. CONCLUSIONS The biocompatible properties of PET were improved while the material was sterilized due to the ultraviolet radiation and free electrons generated during plasma treatment. These results suggest that aminated PET waste films have the potential to be used in biological or biomedical applications by taking advantage of ecofriendly technology such as cold plasma and the reuse of waste polymers such as PET from purified water bottles. © 2022 Society of Chemical Industry (SCI).

The films were characterized by different methods as FTIR, SEM, XRD and TGA to prove the efficient manufacturing of the composite. The dielectric performance measurements were done at frequency of 20 Hz to 6 MHz for the polymer PET and the composite (PPy-Fe2O3)/PET with varying concentrations of Fe2O3. Moreover, to reveal the characteristics of the fabricated composite, the contact angle, the work of adhesion, surface energy of the composite PET/(PPy-Fe2O3) films were considerably determined. The SEM results support the deposition of PPy-Fe2O3 composite on the PET surface. The water contact angle drops from 78.32 o for PET to 40.11o for PET/6%(PPy-Fe2O3), while the dispersive free energy raised from 23.9 mJ/m2 to 43.7 mJ/m2and the polar free energy rises from 8.9 mJ/m2 to 22.3 mJ/m2. The concentration of Fe2O3 increased the surface features of the samples, according to the obtained results. At frequency of 100 Hz, the dielectric constant enhanced from 18 for PET to 923 for the PET/6%(PPy-Fe2O3), and the dielectric loss improved from 24 to 9231, while the energy density improved fromm 7.9x10-5 J/m3 for PET to 408x10-5 J/m3. The TGA results show marginal modifications in thermal stability after deposition the PPy/Fe2O3 on the PET film.
