POLİVİNİL KLORÜR (PVC) ULTRAFİLTRASYON MEMBRAN PERFORMANSININ ÇOK DUVARLI KARBON NANOTÜP KATKISI İLE İYİLEŞTİRİLMESİ

Öz:
Bu çalışmada, faz dönüşüm tekniği ile polivinil klorür (PVC) esaslı karbon nanotüp katkılınanokompozit membranlar hazırlanmıştır. En uygun membran reçetesinin belirlenmesi amacıyla enyüksek saf su akısı ve madde giderimini veren PVP/PVC/çözücü oranı araştırılmıştır. Farklı yüklemeoranlarında (%0,1-3,0, a/a) membran çözeltisine ilave edilen oksitlenmiş çok duvarlı karbon nanotüpler (oMWCNT) ile hazırlanan membranların özellikleri saf membranın özellikleriyle karşılaştırılmıştır.Hazırlanan membranların saf su geçirgenliği ve madde giderimi gibi filtrasyon performans özellikleribelirlenmiştir. Membranların morfolojik özellikleri (gözenekliliği, gözenek boyutu ve dağılımı) TaramalıElektron Mikroskobu (SEM) analizi, hidrofilikliği temas açısı ganyometresi, içerdiği fonksiyonel gruplarFourier Dönüşümlü Kızılötesi (FTIR) Spektroskopisi analizi, ısıl kararlılığı Termogravimetrik Analiz(TGA), mekanik dayanımı ise nanoindentasyon analizi ile tespit edilmiştir. Hidrofobik olan PVC esaslı safmembran matrisine eklenen o-MWCNT’lerin membran hidrofilikliğini arttırarak sadece geçirgenliği vemadde giderimini değil, aynı zamanda membranın yapısal özelliklerini de iyileştirdiği görülmüştür.Deneysel çalışmalardan, %0,5 o-MWCNT’leri içeren nanokompozit membranın en düşük temas açısı veen yüksek porositeye sahip olmasından dolayı, en yüksek akı (356 L/m2sa) ve madde giderimine (%95,6)sahip olduğu tespit edilmiştir.

Performance Enhancement of Polyvinyl Chloride (PVC) Ultrafiltration Membrane by Incorporation of Multi-Walled Carbon Nanotubes

Öz:
In this study, polyvinyl chloride (PVC) based nanocomposite membranes incorporated with carbon nanotubes were fabricated using phase inversion technique. PVP/PVC/solvent ratio was investigated for the highest pure water flux and rejection in order to determine the most suitable membrane recipe. The properties of nanocomposite membranes fabricated in the presence of oxidized multiwalled carbon nanotubes (o-MWCNT) with varying loading levels (0.1-3.0%, by mass) were compared with those of pristine membranes. Filtration performance such as pure water flux and rejection values of the fabricated membranes were determined. Morphological properties (porosity, mean pore diameter and pore distribution), contact angles, functional groups, thermal stability and mechanical strength of the fabricated membranes were determined using Scanning Electron Microscopy (SEM), a contact angle ganiometer, Fourier Transform Infrared Spectroscopy (FTIR) and a nanoindenter, respectively. It has been demonstrated that incorporating hydrophilic o-MWCNTs into the hydrophobic polymeric matrix not only improved the permeability and rejection but also enhanced the membrane structural properties. The results revealed that addition of 0.5% o-MWCNTs into the casting solution provided the highest flux (356 L/m2h) and rejection rate (%95.6) due to having lowest contact angle and highest porosity
