Nano ölçekte Bor Nitrürle Emprenyelenmiş Ahşapta Nano Partiküllerin Dağılımları

Öz

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.
