Abstract

This study aimed to investigate the thermal and electrical behavior of the new copolymer system with chalcone side chain containing anthracene. The structures of monomer and copolymers were characterized using FT-IR, 1H-NMR and 13C-NMR techniques. The thermal behaviors of copolymers have been analyzed by using DSC and TGA. The glass transition temperature was increased from 123 °C to 142 °C with increasing the anthracene content in the copolymer. Semiconducting composites of copolymers have been prepared by adding 4% graphene particles to the copolymer matrix. The dielectric measurements of the copolymers were investigated using the impedance analyzer technique in the frequency range of 100 Hz-20 kHz. The dielectric constant is greatly increase from 5.21 to 273.28 for P(MMA-ko-AAPAc 0.43) by the addition of 4% nanographene. The AC and DC conductivity of copolymer/graphene composites were measured. Furthermore, the activation energy values of the copolymer/4% graphene composites were obtained by measuring the DC conductivity as a function of temperature. The activation energy values of the copolymer/4% graphene composites were 0.320, 0.077 and 0.040 eV for P(MMA-ko-AAPAc 0.16), P(MMA-ko-AAPAc 0.31) and P(MMA-ko-AAPAc 0.43), respectively.

Yeni Antrasen Bazlı Kopolimer Sistemi ve Grafen Kompozitlerinin Hazırlanması, Termal ve Elektriksel Özelliklerinin İncelenmesi

Abstract

Bu çalışma, antrasen içeren kalkon yan zincirli yeni kopolimer sisteminin termal ve elektriksel özelliklerini incelemeyi amaçlamıştır. Monomer ve kopolimerlerin yapıları FT-IR, 1H-NMR ve 13C-NMR teknikleri kullanılarak karakterize edildi. Kopolimerlerin termal davranışları DSC ve TGA kullanılarak analiz edildi. Kopolimerdeki antrasen birimlerinin artmasıyla camsı geçiş sıcaklığının 123 °C'den 142 °C'ye yükseldiği gözlemlendi. Kopolimer matriksine % 4 grafen partikülleri ilave edilerek yarı-iletken kompozitler hazırlandı. Kopolimerlerin ve grafen kompozitlerinin dielektrik ölçümleri 100 Hz-20 kHz frekans aralığında empedans analizör tekniği kullanılarak incelendi. P(MMA-ko-AAPAc 0.43)’ın dielektrik sabiti grafenin ilavesiyle 5.21'den 273.28'e yükseldi. Kompozitlerin aktivasyon enerjisi değerleri, sıcaklığın bir fonksiyonu olarak DC iletkenliği ölçülerek elde edildi. Aaktivasyon enerjisi değerleri P (MMA-ko-AAPAc 0.16), P (MMA-ko-AAPAc 0.31) ve P (MMA-ko-AAPAc 0.43) için sırasıyla 0.320, 0.077 ve 0.040 eV olarak belirlendi.
