Abstract

Cam elyaf takviyeli ve doymamış polyester bazlı polimer kompozit malzemelerin iletkenlik ve dielektrik özelliklerini kontrol etmek için son yıllarda yaygın biçimde kullanılan karbon nanotüpler, yüksek potansiyelli materyallerdir. Bu çalışmada; doymamış polyester bazlı standart levha kalıplama pestili (Sheet moulding compound/SMC) ve yüzde 1,2 oranında tek duvarlı karbon nanotüp (TDKN) ile katkılanmış malzeme için, kritik çalışma parametreleri olan AC elektriksel iletkenliği, dielektrik sabiti, dielektrik kayıp faktörü ve dielektrik dağılım faktörü (kayıp tanjant) değerleri karşılaştırmalı olarak analiz edilmiştir. 50 Hz ve 100 kHz frekans aralığında yapılan ölçümlerden elde edilen sonuçlar, karbon nanotüp katkısının yalıtkan olan malzemenin direncini önemli ölçüde azalttığını ve malzemenin AC iletkenliğini önemli ölçüde arttırdığını ortaya koymuştur. Aynı zamanda katkılı numune için iletkenliğin frekans değişiminden neredeyse bağımsız olduğu da sonuçlardan görülmektedir. Bununla birlikte dielektrik özelliklerin farklı polarizasyon etkileri nedeniyle frekansa bağlı davranış sergilediği ve artan frekans değerlerinde azalma eğilimi gösterdikleri bulunmuştur.
