Abstract

In this study, it was aimed to produce polyvinyl chloride (PVC) hybrid composites in order to utility from the excellent properties of graphene oxide (GO) and to recycle sea shell and to characterize their structural properties. For this purpose, the hybrid compositescontaining 5, 10, 15 and 20 wt.% of milled sea shell powders (DK) and 0.1 wt.% of GO filled were fabricated by colloidal blendingmethod. In the XRF analysis of DK, it was determined that the highest oxide content was calcium oxide (CaO) 98.53 wt.%.According to XRD analysis, hybrid composites with low DK content (5 wt.%-10 wt.%) showed similar results with interlayerdistance, crystallite size and micro strain values of PVC-GO composite. XRD patterns of the hybrid composites with high DK content(15 wt.% and 20 wt.%) showed that graphene peak was not observed except calcite and aragonite phase peaks. As a result, the highDK content caused to exfoliate of graphene in the PVC matrix successfully. DK and GO acted as nucleation centers at 20 wt.% DKcontent and therefore PVC-GO/DK20% hybrid composite had the highest crystal size and the lowest micro-stress values. FTIRanalysis results confirmed that aragonite was the dominant crystal form in the hybrid composites. SEM and EDX analyzes hadpresented homogeneous distributions of DK and GO in PVC polymer matrix and smooth surface images of hybrid composites.

Özet

Bu çalışmada hem grafen oksit (GO)’in üstün özelliklerinden yararlanmak hem de deniz kabuğunun geri dönüşümünü sağlamak içinpolivinil klorür (PVC) hibrit kompozitlerin üretilmesi ve yapısal özelliklerinin karakterize edilmesi amaçlanmıştır. Bu amaçlaağırlıkça (ağ.) % 5, 10, 15 ve 20 öğütülmüş deniz kabuğu tozları (DK) ve ağ. % 0,1 dolgulu GO içeren hibrit kompozitler, kolloidalkarıştırma yöntemi ile üretilmiştir. DK’nın XRF analizinde en yüksek oksit içeriğinin ağ. % 98,53 oranıyla CaO olduğu belirlenmiştir.XRD analizinde düşük DK içeriğinde (ağ. %5-%10) hibrit kompozitlerin, tabakalar arası mesafe, kristal boyut ve mikro gerilmedeğerleri PVC-GO kompoziti ile benzer sonuçlar göstermiştir. Yüksek DK içerikli (ağ. % 15 ve % 20) hibrit kompozitlerin XRDpaternleri, kalsit ve aragonit faz piklerinin dışında grafen pikinin gözlenmediğini göstermiştir. Sonuç olarak, yüksek DK içeriği,grafenin PVC matrisinde başarıyla eksfoliye olmasına sebep olmuştur. %20 DK içeriğinde, DK ve GO’nun çekirdeklenme merkezleriolarak davranması, PVC-GO/DK%20 hibrit kompozitinin en yüksek kristal boyut değerine ve en düşük mikro gerilme değerine sahipolmasına neden olmuştur. FTIR analiz sonuçları, hibrit kompozitlerde baskın kristal formunun aragonit olduğunu doğrulamıştır. SEMve EDX analizleri, DK ve GO'nun PVC polimer matrisinde homojen dağılımlarını ve hibrit kompozitlerin pürüzsüz yüzeygörüntülerini sunmuştur.
