Abstract
Bu çalışmada, iki faz
arasındaki (cam alt tabaka ve BNNSs filmi) yapışmanın arttırılması
amaçlanmıştır. Yüzey iyileştirmesi TEOS silan grubu ve piranha çözeltisi ile
sağlanmıştır. Cam yüzeylerin piranha çözeltisinde tutunma süreleri ve silan
çözeltisinin farklı oranlarının cam yüzeyine yapışması incelenmiştir. Yüzey
karakterizasyonu Fourier Transform Infrared Spektrofotometre (FT-IR) ile
yapılmıştır. Yüzey morfolojisini, ince filmlerin kalınlığını ve bor nitrür
nanosheetlerin yapısını karakterize etmek için Taramalı Elektron Mikroskobu (SEM)
görüntüleri alınmıştır. Eksfoliasyon işleminden sonra bor nitrür nanosheetlerin
verimliliğini belirlemek için UV görünür bölge spektrofotometresi
kullanılmıştır. İnce filmlerin yüzey pürüzlülüğünü belirlemek için yüzey
pürüzlülük cihazı (Time TR200) kullanılmıştır. Sonuçlara göre piranha ve silan
çözeltilerinin cam yüzeyini yapışma için geliştirdiği görülmüştür. SEM
görüntüleri silanın cam yüzeyinde kaplandığını ve kaplama malzemesinin silan
üzerinde tutunduğunu göstermiştir. Silan yüklemesinin fazla olması yapıda
bozulmalara neden olmuştur. Eksfoliasyon sonrası farklı santrifüjleme hızları
için bor nitrür verimi %54,1 ve %34,1 olarak hesaplanmıştır.

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.
