Abstract

Poly(3,4-ethylenedioxythiophene) was synthesized in the presence of a phenothiazine derivative (PTZN_C8). The purpose of the research is to determine the influence of the presence of PTZN_C8 on state of order of forming PEDOT chains and analysis of PTZN_C8 release. Synthesis of PEDOT in the presence of a PTZN_C8 by cyclic voltammetry allowed to characterize the resulting polymer films by determining the accumulated charge capacity. Different synthetic protocols were used to obtain layers of PEDOT as a matrix and phenothiazines derivative as a substance which changed structure of material. Layers were investigated by FTIR to identify the presence of compound incorporated during synthesis. The degree of polymerization was calculated to characterize the length of chains. UV-Vis spectra allowed to calculate the releasing curves of PTZN_C8 from PEDOT matrix. Results showed that PEDOT was modified by changing the length of the chains – as the content of the PTZN_C8 was higher the chains were longer.
