Synthesis of Nano Poly(2-thiophenecarboxaldehyde) and Characterization of Structure

Özet

This article describes a chemical oxidative polymerization for the preparation of nano polymeric thiophene by using FeCl3 as oxidant. 2-thiophenecarboxaldehyde (2-THCA) compound was used as a monomer at this 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 that the polymer is thermally stable up to 450-460 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 theoretically determined data were agree with each other.
