The Effect of Piranha and Silane Modifications on Boron Nitride Nanosheets (BNNSs) Thin Film Formation
Abstract
In this study, the aim was to increase the adhesion between the two
phases (glass substrate and BNNSs film). Surface treatment was provided by TEOS
silane group and piranha solution. The retention times of the glass surfaces in
the piranha solution and the adherence of different ratios of the silane
solution to the glass surface were investigated. Surface characterization was
carried out by Fourier Transform Infrared Spectrophotometer (FT-IR). Scanning
Electron Microscopy (SEM) images were taken to characterize the surface
morphology, the thickness of the thin films and the structure of boron nitride
nanosheets. UV visible spectrophotometer was used to determine the efficiency
of boron nitride nanosheets after the exfoliation process. Surface roughness
tester (Time TR200) was used to determine surface roughness of the thin films.
According to the results, it was observed that the piranha and silane solutions
improved the adhesion of the glass surface. SEM images showed that the silane
was coated on the glass surface and the coating material was retained on the
silane. Excess silane loading caused the structure to deteriorate. Boron
nitride yield was calculated and found to be 54.1% and 34.1% for different centrifugation
rates after exfoliation.
