“…Therefore, both physical and chemical surface treatments of PP have been well developed to improve its adhesive properties. , Several surface modification methods have been employed, such as corona discharge, plasma treatment, and chemical wet oxidation . In the case of corona discharge, oxygen-containing groups are effectively introduced in a single step, but the introduced oxygen functional groups are generally unstable and decrease over time. , In addition, atomic oxygen in the discharge method causes PP chain scission .…”

Metal–plastics adhesion has received much attention from researchers due to its potential use in various industrial applications. However, the adhesion of plastics with metals is poor due to the low surface energy of plastics. Accordingly, the adhesion of plastics usually requires surface modification or the use of an adhesive primer. Recently, we developed a polymer surface modification method using the light-activated chlorine dioxide (ClO2 •) radical as oxidant. In this study, we investigated the adhesion behavior of PP film modified by this method. Improvements in hydrophilicity and adhesion property of PP were observed after oxidation. The oxidized PP film exhibited good adhesive properties with Al plate without any adhesives, and the adhesion strength could be further enhanced by increasing the oxidation temperature. Moreover, this study successfully developed an approach for the electroless metal plating on polymer surfaces. In addition, we also found that light irradiation only activated ClO2 • but had no direct modification on plastics.

“…To our knowledge, however, no prior studies have systematically verified this lack of effect on bulk properties or examined what limits there are to the established beneficial effects of plasma exposure. This paucity of data is concerning for a few reasons: 1) most surgical meshes have relatively high surface-to-volume ratios, 2) plasmas emit photons in the ultraviolet range (Boyd et al, 1997;Jaritz et al, 2017;Liston et al, 1993), 3) ionizing radiation is known to embrittle PP (Abiona and Osinkolu, 2010;Fintzou et al, 2006;Raab et al, 1982;Rabello and White, 1997) and other polymeric materials, and 4) degraded polymer chains at the material surface may resemble nano-scale cracks that could propagate into the bulk of the material upon application of mechanical stress. Considering this, the objective of this work is to evaluate the time-dependent effects of typical nonthermal plasma on both the surface and bulk mechanical properties of surgical mesh devices.…”

Plasma-based treatment is a prevalent strategy to alter biological response and enhance biomaterial coating quality at the surfaces of biomedical devices and implants, especially polymeric materials. Plasma, an ionized gas, is often thought to have negligible effects on the bulk properties of prosthetic substrates given that it alters the surface chemistry on only the outermost few nanometers of material. However, no studies to date have systematically explored the effects of plasma exposure on both the surface and bulk properties of a biomaterial. This work examines the time-dependent effects of a nonthermal plasma on the surface and bulk properties of polymeric implants, specifically polypropylene surgical meshes and sutures. Findings suggest that plasma exposure improved resistance to fibrinogen adsorption and Escherichia coli attachment, and promoted mammalian fibroblast attachment, although increased duration of exposure resulted in a state of diminishing returns. At the same time, it was observed that plasma exposure can be detrimental to the material properties of individual filaments (i.e. sutures), as well as the structural characteristics of knitted meshes, with longer exposures resulting in further embrittlement and larger changes in anisotropic qualities. Though there are few guidelines regarding appropriate mechanical properties of surgical textiles, the results from this investigation imply that there are ultimate exposure limits for plasma-based treatments of polymeric implant materials when structural properties must be preserved, and that the effects of a plasma on a given biomaterial should be examined carefully before translation to a clinical scenario.

“…This was correlated with higher crosslinking of polymer chains, as well as the fragmentation into low molecular weight moieties (ToF-SIMS analysis) after argon plasma treatment. Also, recently, Jaritz et al [ 30 ] performed a comparative study of the effect of argon and oxygen plasmas and that of their isolated radiations on the adhesion of organosilicon coatings on polypropylene. It was shown that the same maximum bond strength enhancement can be reached by pretreating the polypropylene surface either with pulsed oxygen plasma or with only the UV radiation from this oxygen plasma.…”

In this paper, a review of cold plasma setups and the physical and chemical processes leading to the generation of active species is presented. The emphasis is given to the interaction of cold plasmas with materials used in medical applications, especially medical implants as well as live cells. An overview of the different kinds of plasmas and techniques used for generation of active species, which significantly alter the surface properties of biomaterials is presented. The elemental processes responsible for the observed changes in the physio-chemical properties of surfaces when exposed to plasma are described. Examples of ongoing research in the field are given to illustrate the state-of-the-art at the more conceptual level.
