Electrical Conductivity of The Polymers

Öz

Conductive polymers and their blends are compared to other conductive materials, they significantly lighter, good corrosion resistance, easy processability, cost effective and they are comparable with metals. Recent years, lots of R&D works have been conducting for the metal - plastic replacement. These developed materials will be used for aviation, space and defence industry, automotive and automotive subsidiary industry. The most important aspects of the metals are electrical conductivity, electromagnetic interference and radiation shielding are provided with using improved polymers and their blends. Polymers along with their other advantages will replace the metal in the future. In this study, national and international research articles have been compiled on the electrical properties of polymers and their blends, especially in recent years.

POLİMERLERİN ELEKTRİK İLETKENLİĞİ

Öz

İletken polimerler ve karışımları, diğer iletken malzemelerle kıyaslandığında, düşük yoğunluğa sahip, korozyon direnci yüksek işlenmesi kolay, düşük maliyetli ve kullanılan katkılarla birlikte metal ile kıyaslanabilir özellikte iletkenlik değerine sahip olmaktadır. Son yıllarda, metal – plastik değişimi üzerine birçok Ar-Ge çalışması yapılmıştır. Bu çalışmalarda, havacılık, uzay ve savunma sanayi, otomotiv ve otomotiv yan sanayinde kullanılmak üzere önemli polimer ve karışımları geliştirilmiştir. Metallerin en önemli özelliklerinden elektrik iletkenliği, elektromanyetik kalkanlama ve radyasyon emme, geliştirilen polimer ve karışımları ile sağlanabilmektedir. Polimer malzemelerin diğer avantajları ile, gelecekte bu sektörlerde daha fazla metalin yerini alacaktır. Bu çalışmada, polimerler ve karışımlarının elektriksel özellikleri ile ilgili özellikle son yıllarda yapılan ulusal ve uluslararası araştırma makaleleri derlenmiştir.
