PLAZMA POLİMERİZE D-LİMONENE İNCE FİLMLERİN ISLANABİLİRLİK, OPTİK VE KİMYASAL ÖZELLİKLERİ

Bu çalışmada, radyo frekansı (RF) plazma polimerizasyon tekniği ile organik bir bileşik olan D-Limonene esansiyel yağı kullanılarak çeşitli alt tabakalar üzerinde organik bazlı polimer ince filmler elde edilmiştir. İnce filmlerin optik bant aralığı ve absorpsiyon spektrumları Uv-VIS spektroskopisi kullanılarak incelenmiş ve artan RF gücüne bağlı olarak, optik bant aralığı sırasıyla 3,19, 3,25 ve 3,31 eV olarak belirlenmiştir. İnce filmlerin ıslanabilirlik özelliklerini belirlemek için WCA analizleri de gerçekleştirilmiş ve tüm ince filmlerin hidrofilik özelliklere sahip olduğu ve bu özelliklerin artan RF gücünden önemli ölçüde etkilendiği belirlenmiştir. Plazma ile polimerleştirilmiş D-Limonene ince filmlerin, hem morfolojik hem de optik özellikleri göz önünde bulundurulduğunda, bu filmlerin organik bileşik tabanlı olmaları nedeniyle, mevcut elektronik uygulamalarda kullanılanlara alternatif olabileceği düşünülmektedir.

WETTABILITY, OPTICAL AND CHEMICAL CHARACTERISTICS OF PLASMA-POLYMERIZED D-LIMONENE THIN FILMS

In this study, organic based polymer thin films were obtained on various substrates using D-Limonene essential oil, which is an organic compound by radio frequency (RF) plasma polymerization technique. The optical band gap and absorption spectra of thin films were investigated by Uv-VIS spectra and depending on the increased RF power, the optical band gap of the thin films was found to be 3.19, 3.25 and 3.31 eV, respectively. WCA analyzes were also performed to determine the wettability properties of thin films and all thin films had hydrophilic properties and these properties were significantly affected by increased RF power. Considering both the morphological and optical properties of plasma polymerized (pp) D-Limonene thin films, it is thought that these films may be an alternative to those already used in current electronic applications due to their organic compound-based nature.
