Gelişen teknolojiyle birlikte polimerik kompozit malzemeler üstün elektriksel özellikleri sebebiyle dikkat çekmektedir. Günümüzde yüksek yük yoğunluğuna, türevlendirilebilir fonksiyonel gruplara sahip ve elektron transferine olanak sağlayan, düşük maliyetli karbon nanomateryallerin polimerik malzemeler ile birleştirilerek, yeni kompozit malzemelerin üretimi, bu malzemelerin üstün elektriksel ve mekanik özelliklerinden dolayı tercih edilmektedir. Bu sebeple, bu çalışmada, indirgenmiş grafen oksit (rGO) ile modifiye edilmiş indiyum kalay oksit (ITO) kaplı çalışma elektrodu üzerine (E)-4-(2,5-di(tiyofen-2-yl)-1H-pirol-1-yl)-N-(piren-1-ylmetilen) anilinin (PMA) elektrokimyasal yöntemle kaplanmasıyla elde edilen kompozit malzemenin elektrokimyasal özellikleri incelenmiştir. PMA, piren-4-karbaldehit ve 4-(2,5-di(tiyofen-2-yl)-1H-pirol-1-yl)anilinin, kondenzasyon reaksiyonu sonucu başarılı bir şekilde sentezlenmiş ve karakterizasyonu 1H-NMR ile gerçekleştirilmiştir. Elde edilen rGO/pPMA kompozitinin, elektrokimyasal teknikler kullanılarak stabilitesi, yük yoğunluğu, spektroelektrokimyasal teknikler kullanılarak ise optik özellikleri analiz edilmiştir. Elde edilen sonuçlar değerlendirildiğinde, üretilen nanokarbon (NCM) ile desteklenmiş kompozit malzemenin %99’luk mükemmel bir elektrokimyasal kararlılığa ve % 42 gibi akıllı malzemelerde kullanılabilecek yüksek bir optik geçirgenliğe sahip olduğu gözlenmiştir. Gözlenen mükemmel stabilite ve yüksek optik geçirgenlik, üretilen kompozit malzemenin teknolojik uygulamalarda kullanımı için ümit vaat etmektedir.
With the advanced technology, polymeric composite materials are attracted due to their superior electrical properties. Today, combined with polymeric materials of low-cost carbon nanomaterials, which have high load intensity, derivable functional groups and enable electron transfer, the production of new composite materials is preferred due to the superior electrical and mechanical properties of these materials. Therefore, in this study, the electrochemical characteristics of the composite material obtained by the electrochemical method of covering anyline (PMA) (E)-4-(2.5-di(tiyofen-2-yl)-1H-pirol-1-yl) on the work electrode (ITO) covered by reduced graphene oxide (rGO) modified. PMA, pyrene-4-carbaldehyde and 4-(2,5-di(tiophen-2-yl)-1H-pirol-1-yl)anyline were successfully synthesized as a result of a condensation reaction and characterization was carried out with 1H-NMR. The obtained rGO/pPMA composite, using electrochemical techniques, stability, load intensity, spectral electrochemical techniques, and the optical characteristics have been analyzed. When the results were evaluated, it was observed that the composite material supported by the manufactured nanocarbon (NCM) has an excellent electrochemical stability of 99% and an high optical passiveness that can be used in smart materials of 42%. The observed excellent stability and high optical tolerance promise hope for the use of the composite material produced in technological applications.
Polymeric composite materials have gained importance for their superior electrical properties together with the developing technology. Nowadays, the production of novel composites are preferred for their superior electrical and mechanical properties since they enable the electron transfer which has great charge density, derivable functional groups and low cost carbon nano materials are combined with polymeric materials. Thus, in this work, the electrochemical properties of the composite material obtained by (E) -4- (2,5-di (thiophen-2-yl) -1H-pyrrole1 -yl) -N- (pyran-1-ylmethylene) aniline (PMA) coating on the indium tin oxide (ITO) coated electrode modified with reduced graphene oxide (rGO) have been studied. The monomer PMA has been successfully synthesized via condensation reaction of pyrene-4-carbaldehyde and 4- (2,5-di (thiophen-2-yl) -1H-pyrrol-1-yl) aniline and characterization of PMA has been achieved by 1H-NMR. By using electrochemical techniques, the stability, and charge density of the obtained rGO / pPMA composite material and by using spectroelectrochemical techniques, the optical properties of it have been analyzed. As the obtained results have been evaluated, it is observed that the composite material supported by the produced nanocarbon material (NCM) has %99 a complete electrochemical determination and has on average %42, a high optical permittivity to be used in smart materials. The observed complete stability and high optical permittivity are promising for the use of the produced composite material in technological practices.
