Abstract

İletken
polimerler ilginç optik ve elektriksel özellikleri sayesinde teknolojik
uygulamalarda kullanım potansiyeli en yüksek malzemelerden biridir. Fakat
iletken polimerlerin zayıf çözünürlüğü, kolayca işlenememesi, mekanik
dayanımının ve stabilitesinin iyi olmaması gibi nedenler pratik uygulamalarda
kullanımını sınırlandırmaktadır. Bu çalışmada iletken polimerler organik
çözücüler (diklorometan, asetonitril, kloroform vb.) yerine
polistirensülfonikasit yardımıyla hazırlanan sulu dispersiyonunun elektrokimyasal
olarak polimerleştirilmesiyle elde edilmiştir. Böylelikle suda çözünmeyen bir
monomer, çevre ve insan sağlığına zararlı organik çözücüler yerine sulu ortamda
polimerleştirilmiştir. Ayrıca sulu ortamda elde edilen iletken polimerin
organik çözücü varlığında elde edilen iletken polimere göre optik ve
elektriksel özelliklerinin daha üstün olduğu saptanmıştır. Bu makale ile çevre
ve insan sağlığına zararlı organik çözücülerde sentezlenen diğer iletken
polimerlerin de sulu ortamda sentezlenebileceği ve elde edilen polimerlerin
teknolojik uygulamalarda kullanımı için çok önemli olan optik ve elektriksel
özelliklerinin daha üstün olabileceği gösterilmiştir.

Synthesis of conducting polymer with green chemistry and its electrochromic properties

Abstract

Thanks
to their interesting optical and electrical properties, conductive polymers are
one of the materials to have highest potential utility in technological
applications. But theirs usage in practical applications are limited due to
poor solubility, cannot be easily processed and lack of good mechanical
strength and stability. In this work, synthesis of conductive polymer was
achieved in environmentally friendly aqueous dispersion of polystyrene sulfonic
acid instead of harmful organic solvent (dichloromethane, acetonitrile,
chloroform,). Thus, a water-insoluble monomer was polymerized in an aqueous
medium instead of organic solvents which are harmful to environment and human
health. Also, conductive polymer obtained in aqueous medium has superior
optical and electrical properties than the conductive polymer obtained in the
presence of organic solvents. This paper has been shown that other conductive
polymers synthesized in hazardous organic solvents can be synthesized in
aqueous media with superior optic and electrical properties which is important
for the technological application.
