Bu çalışmada polipirol monomeri dekstran biyopolimeri ile 0,3 M okzalik asit çözeltisi içerisinde platin elektrot yüzeyinde ince film halinde kompozit olarak sentezlenmiştir. Sentez işlemi için elektrokimyasal yöntem kullanılarak dönüşümlü voltametri tekniği ile gerçekleştirilmiştir. Sentezlenen ince filmin karakterizasyonu için FT-IR, H-NMR, SEM, UV-VİS, TG-DTA analizleri ve elektrokimyasal açıdan davranışlarının incelenmesi için dönüşümlü voltametri teknikleri kullanılmıştır. Karakterizasyon işlemleri sonucunda sentezlenen kompozit için muhtemel bir kimyasal yapı önerilmiştir. Çözünürlük testleri sonucunda genel olarak çözünmediği ancak DMSO çözücüsünde az miktarda çözündüğü tespit edilmiştir. Elektrokimyasal analizler sonucunda elektroaktif olduğu ve iyi bir redox davranışı gösterdiği belirlenmiştir.

Electrochemical synthesis and characterization of polypyrrolle/dextran composite film on platinum electrode surface

Öz

In this study, a thin film composite of polypyrrole monomer with dextran biopolymer was synthesized on the surface of platinum electrode in 0,3 M oxalic acid solution. For the synthesis process, it was carried out by the technique of cyclic voltammetry using the electrochemical method. FT-IR, H-NMR, SEM, UV-VIS, TG-DTA analyses were used for the characterization of the synthesized thin film and cyclic voltammetry techniques were used to examine its electrochemical behavior. A possible chemical structure was proposed for the composite synthesized as a result of the characterization processes. As a result of the solubility tests, it was found that it was generally insoluble, but slightly dissolved in the DMSO solvent. As a result of electrochemical analysis, it was determined that it was electroactive and showed good redox behavior.
