Abstract

   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.

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

Abstract

   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.
