Yüzeyi Kimyasal Buhar Biriktirme Yöntemiyle Grafen Kaplanmış Gümüş Yüzeyin Yansıtma ve Islatılabilme Özelliklerinin İncelenmesi

Abstract

Malzemelerin yüzey özelliklerinin korunmasında grafen kritik bir nanomalzeme vazifesi görmektedir. Özellikle kimyasal olarak reaktif davranan metal yüzeylerin korozyon dirençlerinin artırılması endüstriyel uygulamalarda önem arz etmektedir. Yapılan çalışmalar pürüzsüz bir atomik yapıya sahip, kimyasal olarak inert, mekanik ve termal kararlılığa sahip olan grafen filmlerin üstün bir korozyon ve oksidasyon bariyeri görevi gördüğünü ispatlamıştır. Gümüş metali, yüksek elektrik ve ısı iletkenliği ile beraber bütün metaller içerisinde en yüksek yansıtma kabiliyeti başta olmak üzere, yüzey plazmon rezonansı gibi birçok üstün optik özelliklere sahip olan bir metaldir. Atmosfer ortamında gümüş her ne kadar oksitlenmese de havada bulunan kükürt içerikli gazlar sebebiyle gümüş yüzeyinde gümüş sülfür (Ag2S) tabakası oluşur ve kararmalar meydana gelir. Oluşan bu tabaka elektriksel, optik ve ıslatılabilirlik gibi yüzey özelliklerini olumsuz etkiler. Bu çalışmada optik ve elektronik uygulamalarda yaygın olarak kullanılan gümüş yüzeylerin kimyasal buhar biriktirme yöntemiyle sentezlenmiş grafen ile kaplanmasının yüzey özelliklerine etkisi, özellikle de ıslatılabilirlik ve yansıtma özelliklerine olan etkileri araştırılmıştır. Bu çalışmada Ag altlık üzerine büyütülen birkaç tabakalı grafen filmlerin temas açıları 96.7o olarak tespit edilmiştir. Yapılan yüzey kaplamaları taramalı elektron mikroskobu (SEM), geçirimli elektron mikroskobu (TEM) ve Raman spektroskopisi çalışmaları ile karakterize edilmiştir.

Investigation of Reflection and Wettability Properties of Graphene Coated Silver Surface by Chemical Vapor Deposition Method

Abstract

Graphene acts as a critical nanomaterial in preserving the surface properties of the materials. It is especially important to increase the corrosion resistance of chemically reactive metal surfaces in industrial applications. Studies have shown that graphene films with a smooth atomic structure, chemically inert, mechanical and thermal stability act as a superior corrosion and oxidation barrier. Silver metal is a metal with many superior optical properties such as surface plasmon resonance, with the highest reflectivity among all metals, together with its high electrical and thermal conductivity. Although silver does not oxidize in the atmosphere, due to the sulfur-containing gases in the air, silver sulfur (Ag2S) layer forms on the silver surface and darkens. This layer adversely affects surface properties such as electrical, optical and wettability. In this study, the effect of coating with graphene synthesized by chemical vapor deposition of silver surfaces commonly used in optical and electronic applications on surface properties, especially on wettability and reflectivity properties were investigated. In this study, the contact angles of few layers graphene films grown on Ag substrate were determined as 96.7o. Fabricated surface coatings were characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM) and Raman spectroscopy.
