POLYESTER/POLİANİLİN,PAMUK/POLİANİLİN KOMPOZİT KUMAŞLARININ ÜRETİLMESİ VE ELEKTRİKSEL ÖZELLİKLERİNİN İNCELENMESİ

Bu çalışmada, pamuk ve poliester ipliklerden üretilmiş dokuma kumaşlar üzerinde anilinin kimyasal polimerizasyonu ile oluşan polianilin ile pamuk ve poliester dokuma kumaşlar kaplanarak iletken kompozit kumaşlar üretilmiştir. Sıcaklık ve nem sabit tutulup, kullanılan anilin oranları değiştirilerek iletkenlik oranlarındaki değişimler gözlenmiştir. Ayrıca çözeltiye gümüş nitrat ilave edilerek iletkenliğe olan etkisi incelendi. İletken polimer ile kumaşı kaplamak için fulard makinesi kullanılmıştır. İletken polimer kaplı tekstil kompozitleri üretmek için farklı deneyler yapılmıştır. Bu deneylerde monomer olarak anilin, oksidant olarak (NH4)2S2O8, yüzey aktif madde olarak Kieralon ED-B, asit olarak ise HCl kullanılmıştır. Ayrıca iletkenliği arttırmak için anilin çözeltisine AgNO3 eklenmiştir. Bütün proseslerin sonunda; Üretilen kompozit kumaşların elekriksel özellikleri ölçülmüştür ve SEM görüntüleri incelenerek polianilinin kumaş yüzeyine ne kadar tutunduğu ve dağılımı gözlenmiştir

PRODUCTION OF POLYESTER/POLYANILINE,COTTON/POLYANILINE COMPOSITE FABRICS AND EXAMINING ELECTRICAL CHARACTERISTICS

In this study, conductive cotton and polyester composite fabrics were produced by chemical polimerization of aniline on fabrics. Variation of rates of conductivities were examined at the different rates of aniline and stable temperature, humidity. Fulard Machine was used for coating fabrics with conductive polymers. Four tests were tried using four different concentrations of aniline in production of composite fabrics coated conductive polymers. In these tests, aniline as monomer, (NH4)2S2O8 as oxidant, Kieralon ED-B as surfactant, HCl as acid were used. Also AgNO3 was added in aniline solution for increasing conductivity. Finally, electrical properties of produced composite fabrics were measured and images of SEM of them were examined to observe polyaniline ratio of holded onto fabrics and the polyaniline distribution of the fabric surfaces
