Abstract:

 Spectroscopic and thermal analyses were conducted on nanocomposite samples prepared by blending PVCPMMA polyvinyl chloridepolymethyl methacrylate with MWCNTs multi-walled carbon nanotubes at different ratios. The PVCPMMACNT composites were prepared using the solution casting method and SEM images showed that the CNTs were homogeneously dispersed. XRD analyses showed that the nanocomposite had an amorphous structure and that the doping of CNTs did not affect the crystallinity. TGA analysis indicated that degradation began at 224 ºC and maximum mass loss was reached at 442 ºC. The Coats-Redfern equation was used to calculate activation energies from the TGA results. DSC analysis showed Tg glass transition temperature values of 64.86 ºC, 61.50 ºC, 70.32 ºC, and 61.80 ºC for PVC20-0, 0.1, 0.5, and 1 samples, respectively. It was observed that there was no clear relationship between the amount of CNT and Tg values. Furthermore, the doping of CNTs did not affect the activation energies of thermal degradation.

 Bu çalışmada farklı oranlarda CNT içeren PVCPMMA blendleriyle hazırlanan nanokompozit numunelerinin, spektroskopik ve termal analizleri yapıldı. Bu amaçla çözücüye ekleme yöntemiyle PVCPMMACNT kompozitleri hazırlandı. SEM görüntülerinde CNTlerin polimer matrise iyi yerleştikleri ve homojen dağıldıkları gözlendi. Nanokompozitin amorf karakterli olduğu XRD analizleriyle görüldü. CNT katkısının, kristallik üzerinde anlamlı bir etkisi olmadığı belirlendi. TGA analizinde bozunmanın 224 ºC de başladığı, maksimum kütle kaybının 442 ºCde 93e ulaştığı saptandı. TGA sonuçlarından Coats -Redfern eşitliğiyle aktivasyon enerjileri hesaplandı. DSC analizinde PVC20-0, 0.1. 0.5, 1 numunelerinde sırasıyla 64.86, 61.50, 70.32, 61.80 ºC olarak ölçüldü. CNT miktarları ile Tg değerleri arasında bir düzenlilik olmadığı gözlendi. CNT katkısının termal bozunmada aktivasyon enerjilerini değiştirmediği gözlendi.
