Bu çalışmada çeşitli oranlarda karbon nanotüp katılmış PVC/PMMA nanokompozitinin termal ve morfolojik özelliklerinin incelenmesi amacıyla PMMA ve PVC gibi iki endüstriyel polimerin blendi ve çok duvarlı karbon nanotüp (MWCNT) katkısıyla bir polimerik nanokompozit hazırlanmıştır. Nanokompozitler, çözeltiden dökme tekniği ile hazırlanmıştır. Polimer blendine, toplam ağırlığın %1, %3 ve %5 oranlarında katılan çok duvarlı karbon nanotüplerin, nanokompozitin termal ve morfolojik özelliklerine etkisi incelenmiştir. Artan oranlı CNT katkısının TGA ve DSC üzerinde küçük değişiklikler yarattığı gözlendi. CNT oranı arttıkça camsı geçiş sıcaklığının (Tg) yükseldiği görüldü. SEM görüntülerinden, CNT ve polimer blendinin uyumlu bir etkileşim sergilediği görüldü.

Investigation of Thermal and Morphological Properties of PVC/PMMA Nanocomposite Added Carbon Nanotube at Various Ratios

Öz

In this study, a polymeric nanocomposite was produced using a blend of two industrial polymers, PMMA and PVC, and a multiwalled carbon nanotube (MWCNT). We achieved this through the investigation of the thermal and morphological properties of PVC/PMMA nanocomposite with carbon nanotubes in various proportions. We prepared the nanocomposites by applying the solution casting technique. We investigated the effect of multiwalled carbon nanotubes added to the polymer blend at 1%, 3%, and 5% of the total weight on the thermal and morphological properties of the blend. Our results indicate that the increase in the ratio of CNT addition causes minor changes in TGA and DSC. Furthermore, the glass transition temperature (Tg) increases as the CNT ratios increases. The SEM images indicate that the CNT and polymer blend exhibits a harmonious interaction.
