Özet:

 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.

 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, 7lik 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.
