“…The coating process was done using radio frequency plasma-enhanced chemical vapor deposition (RF-PECVD). A detailed description of the RF-driven (13.6 MHz) commercially available plasma source (model COPRA DN 400, CCR GmbH, Troisdorf, Germany) is given in references [29,30] and the process of coating is described in detail in references [28,[31][32][33]. The entire coating process consists of two steps.…”

Polymers made of renewable resources increasingly replace conventional plastic materials made of petroleum. Socalled bioplastics can be found e. g. in food industry, for agricultural usage or in the medical field. The range of applications can be further expanded with specialized coating of their surface. Especially in case of food packaging and the usage within medical devices as well as the storage of these composite materials, sterilization or at least the partial reduction of microbial growth is an important issue which needs to be addressed early in the production process. In this work, a commercially available polyhydroxyalkanoate (PHA) pure bioplastic foil of 50 μm thickness was coated with 100 nm of diamond‐like carbon (DLC) and afterwards treated by four different standard methods of sterilization and / or disinfection, namely deep‐freezing, ultraviolet irradiation, autoclaving and immersion in ethanol. The surface morphology of treated DLC‐coated and uncoated samples was investigated and compared to the untreated DLC‐coated and uncoated samples using scanning electron microscopy (SEM) and atomic force microscopy (AFM). Measurements exhibited damage of the composite for autoclaved and in ethanol immersed samples, whereas deep‐frozen and ultraviolet irradiated samples showed no structural changes. These findings clearly demonstrate deep‐freezing and ultraviolet irradiation to be appropriate methods for the disinfection and sterilization, respectively, of the DLC‐coated pure bioplastic foil.

“…The hydrogenated (a-C:H) and non-hydrogenated (a-C) as well as tetrahedrally coordinated amorphous carbons (ta-C) are referred to as DLC (Robertson, 2002), whereas the sp 3 /sp 2 bonded carbon ratio are important factors influencing the biological response of DLC surfaces (Ma et al 2007). These coatings have become quite popular in biomedical applications, particularly in cardiovascular, orthopaedic and ophthalmic applications (Narayan 2005;Mitura et al 2006;Kleinen et al 2008;Fedel et al 2009;Lackner et al 2009;Asakawa et al 2011;Batory et al 2012;Batory et al 2014). They are also used in the modification of the surface of polyurethane presenting good flexibility, still maintaining high level of adhesion (Ohgoe et al 2004;Lackner et al 2009).…”

The aim of this study was to examine the thrombogenic properties of polyurethane that was surface modified with carbon coatings. Physicochemical properties of manufactured coatings were investigated using transmission electron microscopy (TEM), atomic force microscopy (AFM), X-ray Photoelectron Spectroscopy (XPS), Raman spectroscopy and contact angle measurement methods. Samples were examined by the Impact-R method evaluating the level of platelets activation and adhesion of particular blood cell elements. The analysis of antimicrobial resistance against
