Özet

Bu çalışmada eriyik-karıştırma yöntemi kullanılarak ÇDKNT-GNP hibrit nanodolgu ile katkılanmış PC-PBT karışımlarının termal özellikleri ve elektriksel iletkenliklerindeki iyileşmelerin incelenmesi amaçlanmıştır. Diferansiyel tarama kalorimetresi (DSC) ve termogravimetrik analiz (TGA) sonuçları nano-katkı ilavesinin karışım kristalliklerini arttırdığını göstermiştir. Bunun yanında, yüksek katkı oranlarında numunelerin termal kararlılığında önemli bir düşüş gözlemlenmiş olup bu durum polimer matriks içindeki faz geçişlerine bağlanmıştır. Ağ. %5 katkı oranına sahip numunede iletken bir ağ elde edilmiş olup, %7'lik ağırlıkça katkı oranında elektriksel iletkenlikte düşüş gözlemlenmiş ve bu durum topaklaşma (aglomerasyon) etkisine bağlanmıştır. Elde edilen deneysel sonuçlar hibrit nanokompozitlerde üstün termal ve elektriksel performans elde edilmesi için nano-katkı kompozisyonunun optimizasyonunun önemini vurgulamaktadır.

Abstract

This study aims to examine the improvement of thermal properties and electrical conductivity of PC-PBT blends through reinforcement with hybrid MWCNT-GNP nanofillers via melt-mixing. Differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA) showed that the incorporation of nanofillers increased the crystallinity of the blends. On the other hand, a marginal decline in thermal stability was observed in the case of higher filler concentrations which was ascribed to the phase transitions within the polymer matrix. A conductive network was achieved with 5% wt. MWCNT-GNP weight fraction, and a notable reduction of 7 % was observed which was attributed to agglomeration effects. These findings reveal the importance of optimizing nanofiller concentration to achieve superior thermal and electrical performance in hybrid nanocomposites.
