“…Characterization of GO and the GO/UHMWPE composites was carried out as detailed in our preliminary study. [22][23][24][25][26][27][28][29][30] Aer that, some samples and VE solution were placed in beakers, and the beakers were placed in a drying oven to soak at 120 C for 24 h. Aer reaching the specied time, the samples were removed from solution and put in a drying oven at 120 C for 24 h for homogenization treatment, followed by cooling down and wiping off the excess VE.…”

“…Also, it was observed that the low amount of RGO that resulted in the maximum wear resistance. These results may be attributed to the excellent mechanical properties and high specific surface area of RGO, which facilitates good load transfer to the RGO network [12]. It could be seen that after adding the content of RGO into UHMWPE matrix, the friction coefficient of biocomposites decreased significantly.…”

“…At the same time, they have antibacterial properties and they were often used for biomedical applications recently [10]. There are studies to investigate tribological properties of UHMWPE composites by using GO [5,[11][12][13] and GNP [14,15] but to the best of our knowledge, there are no report on the green synthesis of RGO for UHMWPE and their effects on the tribological properties of UHMWPE biocomposites, in the literature. Bhattacharyya et al reported that UHMWPE nanocomposite films was produced with RGO using two different process routes.…”

“…718 cm -1 dalga sayısında görülen CH2 sallanma titreşim piki UHMWPE' nin uzun moleküler zinciri ve yüksek derecede polimerizasyonundan kaynaklanmaktadır [4]. Kompozitin FTIR spektrumuna bakıldığında yukarıda UHMWPE için verilen dalga sayılarında ki gerilme titreşimlerine ek olarak ve 1093 ve 1020 cm -1 dalga sayılarında diğer karbon bağlarına ait (C-O-C) piklerin şiddetinde de artışlar görülmektedir [12]. Bu durum CRGO' nun UHMWPE' nin moleküler yapısı üzerinde etkisi olduğunu yani dolgu-matriks etkileşiminin sağlandığını göstermektedir.…”

“…Şekil 4 kompozit örneğinin aşınma öncesi SEM yüzey görüntüsünü göstermektedir. Kompozit yüzeyi yapının kristalliğini yansıtmaktadır [12]. Ayrıca oksijen içermeyen polimer matrikse oksijen içeren CRGO' nun dağılımının ayırt edilmesi için EDS haritalama analizi kullanılmış ve analiz sonucu Şekil 5'de gösterilmiştir.…”
