Farklı Karbon Dolgular İçeren Kitosan Filmlerin Elektrik ve Optik Özelliklerinin İncelenmesi

Öz

Bu çalışmada Kitosan (CS) matris içerisine grafen oksit (GO), gözenekli karbon (CM), grafen nanoplatelet (GNP) ve çok duvarlı karbon nanotüp (MWCNT) gibi karbon dolgular (KD’lar) eklenerek elde edilen ince filmlerin elektrik ve optik özelliklerindeki değişimler incelenmiştir. Filmleri hazırlamak için çözelti karıştırma, ultrasonik karıştırma ve döndürerek kaplama teknikleri kullanılmıştır. CS/KD ince filmlerin elektrik ve optik özelliklerinde önemli ölçüde iyileşmeler sağlandığı görülmüştür. Ayrıca bu KD’lar arsında bir kıyaslama yapılmış ve fiziksel özellikleri arttırmada MWCNT’ün diğer KD’lara göre daha etkili olduğu gözlemlenmiştir. Elde edilen elektriksel ve optik sonuçlar, CS/KD biyokompozitlerin sürdürülebilir ve geçici optoelektronik, foton enerjisi uygulamaları, biyotıp ve biyosensör uygulamalarında kullanılabileceğini göstermektedir.

Investigation of Electrical and Optical Properties of Chitosan Films Containing Different Carbon Fillers

Öz

In this study, the changes in the electrical and optical properties of thin films obtained by adding carbon fillers (CFs) such as graphene oxide (GO), carbon mesoporous (CM), graphene nanoplatelet (GNP) and multi-walled carbon nanotube (MWCNT) into the chitosan (CS) matrix were investigated. Solution mixing, ultrasonic mixing and spin coating techniques were used to prepare the films. Significant improvements were observed in the electrical and optical properties of CS/CF bio-composite thin films. In addition, a comparison was made between these CFs and it was observed that MWCNT was more effective than others in increasing physical properties. Obtained electrical and optical results show that CS/CF biocomposite films can be used in sustainable and temporary optoelectronics, photon energy applications, biomedicine and biosensor applications.
