Abstract

Termal kararlılık, ahşap materyallerin en önemli
özelliklerinden biridir. Bu yüzden birçok çalışma termal kararlılığı
iyileştirmek için yürütülmektedir. Nanoteknoloji geleneksel metotlarla
sağlanamayan termal kararlılığı artırmak için önemli bir fırsat sunmaktadır.
Odun içerisinde nanopartiküllerin dağılımları ne kadar iyiyse odunun termal
kararlılığındaki iyileşme daha yüksek olmaktadır. Bu çalışmada; odun, vakum ve
basınç oranları kontrol edilebilen bir kabin içerisinde %3lük bir nano boyutta
bor nitrür (BN) çözeltiyle emprenye edilmiştir. Emprenye sonrasında, SEM/EDX
analizi, nanopartiküllerin dağılımını belirlemek için yürütülmüştür. SEM
resimlerine göre, geçit ve hücre duvarları üzerinde bazı BN kalıntılarına
rastlanmıştır. Buna karşın bu BN kalıntılarının yüzeyin (örnekler 30 mm
kalınlığındadır) 10 mm derinliğine kadar görüntülenebilmiştir.

Distribution of Nano Particles in the Wood Impregnated with Nano Scale Boron Nitride

Abstract

Thermal stability is the one of the most
important properties of wood materials. Therefore, many papers have been
conducted to improve the thermal instability. Nanotechnology offers an
important opportunity to improve the thermal stability that cannot be provided
by traditional methods. Nanoparticles distribution inside the wood is an
economical and simple method to improve the thermal properties of wood. In this
study, wood was impregnated with nano-sized boron nitride (BN) with a solution
of 3% in a vessel which can be controlled the ratio of vacuum and pressure.
After impregnation, SEM/EDX analysis was conducted to determine the
distribution of nano particles. According to SEM pictures, some deposits of BN
on the pits and the cell wall were found. However, the BN deposits were only
viewed until 10 mm deeply (samples are 30 mm thickness) under the surface.
