Abstract

This
article describes a chemical oxidative polymerization for the preparation of
nano polymeric thiophene by using FeCl3 as oxidant. 2-thiophenecarboxaldehyde
(2-THCA) as monomer was used at polymerization process. The structure of
synthesized nano polymeric thiophene was confirmed by  scanning electron microscopy (SEM), Fourier
transform infrared spectroscopy (FTIR), Thermogravimetric analysis (TGA), Raman
Spectroscopy, and elemental analysis of C, H, O and S. SEM images showed that
the poly(2-thiophenecarboxaldehyde) (PTHCA) was synthesized in nanoscale and had
a homogeneous and smooth structure. The size of the synthesized nano particles
was not more than 35 nm. Thermal analysis of nano polymeric thiophene showed
thermally stable up to 512 OC. When elemental analysis results of PTHCA were
examined, it was seen that the obtained data after the synthesis of nano
polymeric thiophene and the determined data theoretically were agree with each
other.

Nano Polimerik Tiyofenlerin Hazırlanması ve Yapılarının Karakterizasyonu

Abstract

Bu çalışma, oksidant
olarak FeCl3 kullanarak nano polimerik tiyofenin hazırlanması için kimyasal
oksidatif polimerizasyonu açıklamaktadır. Polimerizasyon prosedüründe monomer
olarak 2-tiyofenkarboksialdehit kullanılmıştır. Sentezlenen nano polimerik
tiyofenin yapıları, taramalı elektron mikroskobu (SEM), Fourier transform
infrared spektroskopisi (FTIR), Termogravimetrik analiz (TGA), Raman
Spektroskopisi ve C, H, O ve S'nin elemental analizi ile doğrulanmıştır. SEM
görüntüleri ile polimerin nano boyutlarda sentezlenmiş olduğu, homojen ve
pürüzsüz bir yapıya sahip olduğu tespit edilmiştir. Oluşan parçacıkların
boyutlarının 35 nm'den fazla olmadığı görülmüştür. Nano polimerik tiyofenin
termal analizi polimerin 512 OC'ye kadar termik olarak stabil olduğunu
göstermiştir. Elementel analiz sonuçları incelendiğinde, nano polimerik
tiyofenin sentezi sonucu elde edilen veriler ile teorik olarak belirlenen
verilerin birbiri ile uyum içerisinde olduğu görülmüştür.
