“…A similar effect after the deposition of two different diamond-like carbon structures (flexible-DLC and robust-DLC) was described by Catena et al [1]. This shows that in most cases plasmochemical treatment causes the contact angle to decrease, which was discussed broadly in many papers [2,10,45,46]. Polyethylene with N-DLC coating (PE_2 series) is probably the best for biomedical applications, because it exhibits low and comparable water and diiodomethane contact angles.…”

“…Therefore, special surface treatments must be applied to improve the physicochemical properties. This can be achieved using thin layer technology, including oxygen and nitrogen plasma discharge [3], laser irradiation [4,5], deposition of anti-wear and/or functional coatings (i.e., diamond-like carbon (DLC)) [6][7][8] and immobilization of biopolymers (e.g., chitosan and its derivatives) [9,10]. Since plasma treatment results in the generation of high-energy species such as radicals, ions, or molecules in an excited electronic state, this enables surface reactions to take place and leads to surface activation and modification [11].…”

In this paper, the surface properties and selected mechanical and biological properties of various multi-layer systems based on diamond-like carbon structure deposited on low-density polyethylene (LDPE) substrate were studied. Plasma etching and layers deposition (incl. DLC, N-DLC, Si-DLC) were carried out using the RF CVD (radio frequency chemical vapor deposition) method. In particular, polyethylene with deposited N-DLC and DLC layers in one process was characterized by a surface hardness ca. seven times (up to ca. 2.3 GPa) higher than the unmodified substrate. Additionally, its surface roughness was determined to be almost two times higher than the respective plasma-untreated polymer. It is noteworthy that plasma-modified LDPE showed no significant cytotoxicity in vitro. Thus, based on the current research results, it is concluded that a multilayer system (based on DLC coatings) obtained using plasma treatment of the LDPE surface can be proposed as a prospective solution for improving mechanical properties while maintaining biocompatibility.

“…star polymers [27]. Plasma treatment was also used for immobilization of different types of different biopolymers, such as chitosan on low-density polyethylene for bio-medical applications [28]. DC plasma was also successfully used for biocompatibility enhancement of polymethylpentene [29], PLLA [30] or PHB [31].…”

“…Monomers also undergo plasma polymerization because the treated surface is rich in radicals. Furthermore, plasma treatment is known to immensely enhance surface properties, while its penetration depth is limited to only a few nanometers [36][37][38][39][40]. In fact, the thinness/surface-specificity of the newly formed layer at the polymer interface is often regarded as an advantage of plasma treatment as the propitious bulk properties are preserved.…”

Modification of Polyethylene by RF Plasma in Different/Mixture Gases

Herein, low-density polyethylene (LDPE) films were treated using radio-frequency plasma discharge in the presence of air, nitrogen, oxygen, argon, and their mixtures to introduce new chemical functionalities. The surface properties of treated LDPE were qualitatively and quantitatively characterized using various analytical and microscopic techniques. It was found that the optimum plasma treatment for LDPE occurs in the presence of air plasma at an exposure time of 120 s and 80 W of nominal power. The plasma formed layer had tendency to increasing thickness with increasing treatment time up to 60 s using air and oxygen and even more with inert gases. An aging study of plasma-treated LDPE samples stored in ambient air or water medium revealed the partial hydrophobic recovery.
