“…After plasma treatment, the C/O ratio increased to 2.4, meaning that oxygen containing chemical groups were reduced during the plasma treatment, due to PLCL surface degradation. This observation can be explained by ester group scissions followed by decarboxylation step as already described in literature on polyesters 26 - 28 . This hypothesis was also correlated by the significant drop in the relative area of O–C = O peak in the C1s HR spectrum (Fig.…”

Thermoplastic biodegradable polymers displaying elastomeric behavior and mechanical consistency are greatly appreciated for the regeneration of soft tissues and for various medical devices. However, while the selection of a suitable base material is determined by mechanical and biodegradation considerations, it is the surface properties of the biomaterial that are responsible for the biological response. In order to improve the interaction with cells and modulate their behavior, biologically active molecules can be incorporated onto the surface of the material. With this aim, the surface of a lactide and caprolactone based biodegradable elastomeric terpolymer was modified in two stages. First, the biodegradable polymer surface was aminated by atmospheric pressure plasma treatment and second a crosslinker was grafted in order to covalently bind the biomolecule. In this study, albumin was used as a model protein. According to X-ray photoelectron spectroscopy (XPS) and atomic force microscopy (AFM), albumin was efficiently immobilized on the surface of the terpolymer, the degree of albumin surface coverage (ΓBSA) reached ~35%. Moreover, gel permeation chromatography (GPC) studies showed that the hydrolytic degradation kinetic of the synthesized polymer was slightly delayed when albumin was grafted. However, the degradation process in the bulk of the material was unaffected, as demonstrated by Fourier transform infrared (FTIR) analyses. Furthermore, XPS analyses showed that the protein was still present on the surface after 28 days of degradation, meaning that the surface modification was stable, and that there had been enough time for the biological environment to interact with the modified material.

“…With the development of polymer industry and NTP technology, more and more gases were used as discharging gas for polymer web surface treatments. For example, for the aim of improving hydrophilicity, the discharge gas can be the non-polymerisable gas such as Ar [96,97], He [98,99], Air [100][101][102], O 2 [103,104], N 2 [104,105], NH 3 [106], CO 2 [107,108], while CF 4 [109][110][111] or other CF-based compounds monomers [112,113] were used to obtain hydrophobic film. Reactive O 2 plasma is known to introduce a mixture of mainly carboxyl group (-COOH) and hydroxyl group (-OH) functionalities, while N 2 or NH 3 plasma introduces amines on the polymeric surfaces.…”

This review describes the application of non-thermal plasma (NTP) technology for high barrier layer fabrication in packaging area. NTP technology is considered to be the most prospective approaches for the barrier layer fabrication over the past decades due to unpollution, high speed, low-costing. The applications of NTP technology have achieved numerous exciting results in high barrier packaging area. Now it seemly demands a detailed review to summarize the past works and direct the future developments. This review focuses on the different NTP resources applied in the high barrier area, the role of plasma surface modification on packaging film surface properties, and the deposition of different barrier coatings based on NTP technology. In particular, this review emphasizes the cutting-edge technologies of NTP on interlayer deposition with organic, inorganic for multilayer barriers fabrication. The future prospects of NTP technology in high barrier film areas are also described.

[4][5][6][7][8] Inagaki et al investigated the modification of PET by Ar, O 2 , H 2 , N 2 , and NH 3 plasmas. They found that the O 2 , Ar, and N 2 plasmas preferably modified the CH 2 groups or phenyl rings while H 2 and NH 3 plasma mainly modified ester groups.…”

Polyethylene terephthalate (PET) surface modification by VUV and neutral active species in remote oxygen or hydrogen plasmas

Polyethylene terephthalate (PET) are exposed either by VUV photons emitted from oxygen or hydrogen plasmas or by VUV photons and neutral active species from both plasmas. The water contact angle (WCA) of PET surface increased after treatment with H2 VUV + H atoms, due to the cleavage of the oxygen‐containing groups by VUV photons. The WCA decreased for the case of treatment with O2 VUV + O‐related neutral active species, leading to be released the polar groups like −COH or −COOH from the PET surface with a depth of less than about 10 nm. Oxygen‐related neutrals etched the PET film and generated a rough surface which also contributed to the decrease in WCA however no bulk chemical structure obviously changed.
