“…To broaden its applications in industrial field, the surface modification of PTFE has been explored by several methods, such as low-pressure plasma processing [9], atmospheric pressure plasma jet [10], particle beam irradiation [11], irradiation of synchrotron radiation (SR) [12], surface graft polymerization [5] and ''wet'' chemical treatment [13]. All of these treatments lead to improvements in adhesion and wettability.…”

ÖzetBu çalışmada yapay damar malzemesi olarak kullanılan ePTFE numunelerine metal+gaz hibrid iyon implantasyonu yapılarak antibakteriyel ve süperhidrofob özellikler kazandırılmıştır. Çalışmanın amacı, kalp ve damar cerrahisinde kullanılan genişletilmiş politetrafloroetilen (ePTFE) yapay damarlarda oluşan sorunların giderilmesi amacıyla iyon implantasyonu yapılan ePTFE numunelere kazandırılan bazı özellikleri incelemektir. Çalışma, ePTFE numune yüzeylerinin Ag + iyon implantasyonu ile modifiye edilmesi, modifiye edilmiş bu malzemelere antibakteriyel test yapılarak bakteri azalmasının incelenmesi, modifiye edilmiş malzemelerin temas açılarının ölçülmesi ve modifiye edilmiş ePTFE yüzeylerin AFM ile yüzey pürüzlülüklerinin ölçülmesini içermektedir. Sonuç olarak, Ag + ile gerçekleştirilen implantasyonlarda, temas açıları ölçüldüğünde malzeme süperhidrofob özel-lik sağlanmıştır. Antibakteriyel test sonuçlarında ise, S.aureus bakterisiyle yapılan testlerde S.aureus bakterisinin azaldığı görülmüştür. İyon implantasyonu yapılmış numunelerde yüzey pürüzlülük değerlerinin belirgin olarak azaldığı görülmüştür.Anahtar Kelimeler -İyon implantasyonu, MEVVA, Ag, antibakteriyel, ePTFE Surface Characteristics and Antibacterial Activity of Ag-Silver Ion Implanted PolyThetraFluoroEthylene (PTFE) as a Cardiovascular Surgery Material AbstractIn this work, ePTFE samples, which have been used as artificial vein materials, were metal+gas hybrid ion implanted to gain antibacterial and superhydrophobe properties. The purpose of this study was to study some properties of ion implanted expanded-polytetrafluoroethylene samples, which are used in cardiovascular surgery, with the purpose of eliminating the problems. The work consists of surface modification of ePTFE samples by Ag + ion implantation, study of the antibacterial properties of these ion implanted samples by antibacterial tests, contact angle measurements of ion implanted samples and measurements of surface roughness of ion implanted ePTFE surfaces by AFM. Experimental results showed that superhydrophobicity were obtained by ion implantation. Antibacterial tests showed that S.aureus bacteria were decreased after ion implantation. It was observed clearly that the roughness of ion implanted ePTFE surfaces decreased.
