“…The major research in this field has been conducted on the influence of plasma treatment under different working environments on PVC surface chemistry [43,44,45,46,47,48,49,50,51,52,53,54,55,56,57,58,59,60,61,62,63,64,65,66]. This may be because of the solvent-free basis of the method which is of importance from an environmental viewpoint.…”

“…It was seen that treating PVC surface in plasma led to the C–C, C–Cl, and C–H bonds scission since the induced energy exceeded the bonds dissociation energy [43,44,45,46,47,48,49,50,51,52,53]. Plasma exposure in an inert gas gave rise to the generation of metastable species, that is, carbon radicals (Figure 1) on PVC surfaces which could either form a crosslinked network or be oxidized to give new functionalities, in case the treated surface was exposed to air [43,44,45,46,47,48,49,50,51,52,53,54,55,56,57,58]. Provided oxygen or air was operated as the working gas, carbonyl, carboxyl, peroxide, and ester groups were most probable to form [59].…”

“…One of the most important classes of medical devices are catheters, which can be used as diagnostic tools and also as clinical tools [1]. Catheters are used in treating vascular diseases and can also provide fluid administration, parenteral nutrition, hemodynamic monitoring, blood sampling, and administration of drugs [2,3,4,5,6,7,8,9]. Also, such devices have some important drawbacks, such as structure failure, calcifications, infections, thrombosis, etc.…”

Background and objectives: Medical devices such as catheters are used on a large scale to treat heart and cardiovascular diseases. Unfortunately, they present some important drawbacks (structure failure, calcifications, infections, thrombosis, etc.), with the main side effects occurring due to adhesion and proliferation of bacteria and living cells on the surface of the implanted devices. The aim of this work is to modify the surface of polyvinyl chloride (PVC), an affordable biocompatible material, in order to reduce these aforementioned side effects. Materials and Methods: The surface of PVC was modified by depositing a thin layer also of PVC that incorporates an active substance, dicoumarol (a well-known anticoagulant), by spin coating process. The modified surfaces were analyzed by Fourier-transform infrared (FT-IR) microscopy, Fourier-transform infrared (FT-IR) spectroscopy, Ultraviolet-visible spectroscopy (UV-VIS), and Scanning electron microscopy (SEM) in order to determine the surface morphology and behavior. The samples were tested for Gram-positive (S. aureus ATCC 25923) and Gram-negative (P. aeruginosa ATCC 27853) standard strains from American Type Culture Collection (ATCC). Results: The material obtained had a smooth surface with a uniform distribution of dicoumarol, which is released depending on the deposition parameters. The concentration of dicoumarol at the surface of the material and also the release rate is important for the applications for which the surface modification was designed. PVC modified using the proposed method showed a good ability to prevent salt deposition and decreased the protein adhesion, and the resistance to bacterial adherence was improved compared with standard PVC.
