Effect of Glass Surface Treatment on Boron Nitride Thin Film Formation

Abstract

Boron nitride (BN) has extensive applications due to its many unique features. It is believed that BN crystal structure with an exposed crystal surface will benefit from many unique properties, such as excellent high thermal conductivity, mechanical strength. Thanks to these features thin Il-BN coatings find applications in several fields such as protective coating for oxidation, UV, humidity and corrosion. Adhesion is one of the most important factors in thin film formation. In order to increase the adhesion between the two phases (glass substrate and film), the glass surface must be treated before coatlng. In this study, after the glass surfaces were treated using TEOS silane group and piranha solution, the coating was applied. The retention times of the glass surfaces 111 the piranha solution and the adherence of different ratios of the silane solution to the glass surface were investigated. Fourier Transform Infrared Spectrophotometer (FT-IR) analysis was performed for analysis of bond stmctures of the components in the thin film structure. Scanning Electron Microscopy (SEM) images were taken at different magnification ratios to define the sufface morphology of the thln films. When the results were examined, it was observed that the piranha and silane solutions improved the glass surface. Accordlng to the SEM Images, the silane was coated on the glass surface and the coating matenal was held on the silane,
