“…It is also worthwhile to mention that the maximal WCA value is still much lower than the WCA of the untreated LDPE surface, which means that the major part of the surface wettability is kept after plasma treatment. Ageing after an argon DBD plasma treatment results in a loss in treatment efficiency of 50.0 ± 3.4 % after 2 days of ageing [27] while after an oxygen plasma treatment in a parallel plate reactor the loss in treatment efficiency is even 81% after 2 days of ageing [28]. This means that the ageing of the APPJ treated samples is quite slow since the loss in treatment efficiency is much lower compared to other ageing behaviours previously described in literature.…”

The surface properties of polyethylene can successfully be altered using argon plasmas. In this work, the surface modification of low density polyethylene (LDPE) using an argon atmospheric pressure plasma jet (APPJ) is profoundly investigated. The surface modification is examined using different analysing techniques namely, water contact angle (WCA) measurements for the wettability and X-ray photoelectron spectroscopy (XPS) for the chemical composition. Particular attention is paid to the treatment distance between the plasma jet capillary and the LDPE foil and the applied treatment time. At treatment distances between 5 and 15 mm, the WCA can be reduced with more than 70% within a treatment time of a few ms. XPS measurements reveal that this is due to the incorporation of oxygen containing groups and especially the increased implementation of the O-C=O group has a big influence. At treatment distances above 15 mm, the wettability decreases with increasing treatment distance. The wettability can however be enhanced by increasing the treatment time. Ageing considerations show that the loss in treatment efficiency is restricted to only 25%, meaning that even after 14 days of ageing the WCA reduction upon plasma treatment is still more than 40%. Based on the above mentioned results, the most appropriate parameters can thus be selected to provide an efficient plasma treatment of LDPE using the argon APPJ.3

Plasma treatment is a versatile tool for surface modifications, and plasma-induced hydrophilicity has a well-known aging behavior. In this paper, plasma hydrophilization and the subsequent aging behavior of superhydrophobic and hydrophobic surfaces are comparatively investigated. Static water contact angle measurement and X-ray photoelectron spectroscopy show that, compared with the hydrophobic surface, the superhydrophobic surface requires more plasma dose to completely change its wettability even after considering the difference in their initial wettability, and the corresponding aging speed is also obviously retarded. A tentative model based on the surface micro/nanostructures is presented to explain the results.

“…During storage, the polymer will try to lower the introduced surface energy by reorienting its plasma treated polymer chains into the bulk of the surface. This dynamic process has been extensively studied and by applying the right storage conditions (low temperatures/ vacuum environment) the plasma treatment effect can be preserved for a relatively longer time [44][45][46][47][48][49].…”

Plasma assisted surface patterning is becoming a well-established technique that introduces both alternating surface texture and chemistry on substrates for biomedical applications. This review consists of an overview on the developments in this field over the last 15 years. Special attention is given to the different kinds of chemistry that can be introduced and their effect on the surface-cell interaction, as well as their feasibility for possible applications in the field of regenerative medicine.
