aThe in-depth oxygen diffusion into a low density polyethylene film is performed in the post-discharge of an atmospheric plasma torch, supplied in argon as carrier gas and with or without oxygen as reactive gas. The chemical and structural properties of the polymer surface and bulk are studied in terms of plasma parameters (treatment time, power, and reactive gas flow rate). A good correlation between XPS and Fourier transform infrared spectroscopy analyses is demonstrated. The penetration depth of oxygen into the bulk of the polymer is investigated by angle resolved-XPS and time-of-flight SIMS. It is shown that, depending on the plasma conditions, oxygen could penetrate up to 20-40 nm into the low density polyethylene during the atmospheric plasma treatment.

“…The polymer has the following physical characteristics: K w value: 72; powder, density: from 0.48-0.56 g.cm 23 . The additives used in the preparation of the various formulations are dioctyl phthalate (DOP) as a plasticizer with a viscosity range from 75-80 CSt, a molecular weight of 390 g.mol 21 , and a boiling temperature of 231 C. Ca/Zn type Lankromark LC486, produced by Akros Chemicals, and stearic acid were also used as stabilizer and lubricant, respectively. ORF, having a diameter of around 100 mm, was used as the reinforcing agent.…”

“…Residue formation for the treated compositions is higher than that of untreated samples. This can be explained by an increase in intermolecular hydrogen bonding due to the formation of the hydroxyl and hydroperoxide groups after irradiation [21]. Irradiation treatment marginally improves the interfacial adhesion between PVC and ORF.…”

In this study, gamma irradiation treatments were used to improve the compatibility between poly(vinyl chloride) (PVC) and olive residue flour (ORF). The blends were subjected to gamma irradiation at doses of 10 and 70 kGy. The mechanical, thermal, and morphological behaviors of those blends have been assessed. The irradiated blends exhibit better thermal properties, higher tensile modulus, elongation, and strength at break than those of unirradiated blends. The contact angle of water on the surface of a blend irradiated at doses of 10 and 70 kGy is smaller than that for their corresponding unirradiated blend. These treatments cause surface oxidation of PVC/ORF films, as revealed by Fourier transform infrared (FTIR) spectroscopy analysis. J. VINYL ADDIT.

The ability of non-equilibrium plasmas to modify surfaces has been known for many years. And a promising way to perform surface modifications without altering the bulk properties is plasma polymerization since this technique is versatile and can be applied to a wide range of materials. Plasma polymer films usually show good biocompatibility when compared to classical biomaterials. The possible biomedical use of plasma polymers motivates the study of their behavior during storage and in aqueous environment. Therefore, it is of major importance to understand the change of properties of these plasma polymers over time and when in contact with certain fluids. Recently, plasma polymer gradients (surfaces that display a change in at least one physicochemical property over distance) have attracted significant attention from the biomedical filed where the interaction of cells with a material surface is of major interest. This chapter discusses biomaterial functionalization via plasma polymerization focusing on their use in the biomedical field as well as their aging and stability behaviors. Plasma polymer gradients as valuable tools to investigate cell-surface interactions will also be reviewed.
