Smart Nano Biomimetic Hydrothermal Location on Wooden Surface

Öz

The aim of this study is to make nono-dimensional functionalization on the wooden surface by using hydrothermal method and thus to ensure that the surface exhibits a smart orientation towards environmental conditions. Ferrous sulfate heptahydrate (FeSO4·7H2O), Chromium (II) chloride (CrCl2), Sodium hydroxide (NaOH), Ethyl alcohol (EtOH) and Potassium nitrate (KNO3) chemicals were used in the first part of the two-stage functionalization process on the lignocellulosic surface. Thus, a surface with anti-UV property was obtained. Octadecyltrichlorosilane (OTS, 95%) was used in the second step, Hydrophobization. Fourier transform infrared spectroscopy (FTIR), Scanning electron microscopy (SEM), X-ray diffraction (XRD) and Energy diffuser x-ray (EDX) instrumental analyzes were used to characterize the modification applications. Hydrophobicity was determined by measuring the water contact angle (WCA) of the new functional surface. Its anti-UV feature was determined by UV-Vis spectrometry. As a result of the characterization studies, hydrothermal nano functioning has been proved to be successful. The water contact angle of the new surface was measured as θγ 128 °. It has anti-UV properties in the area where the wavelength range is 200-800 nm. It has anti-UV properties in the area where the wavelength range is 200-800 nm. After functioning, surface change parameters were made according to ISO 4287 standard. Color change rates are determined in accordance with ISO 2469 (2014) standards.

Ahşap Yüzeyde Akıllı Nano Biyomimetik Hidrotermal Lokasyonlama

Öz

Bu çalışmanın amacı, ahşap yüzeyde hidrotermal metod kullanılarak nono boyutta fonksiyonlandırma yapmak ve böylelikle, yüzeyin çevre şartlarına karşı akıllı bir yönelim sergilemesini sağlamaktır. Lignoselülozik yüzeyde iki aşamalı oluşturulan fonksiyonlandırma sürecinin ilk kısmında Demirli sülfat heptahidrat (FeSO4·7H2O), Krom (II) klorür (CrCl2), Sodyum hidroksit (NaOH), Etil alkol (EtOH), ve Potasyum nitrat (KNO3) kimyasalları kullanılarak öncelikle anti-UV özellikli bir yüzey elde edilmiştir. Ikinci basamak olan Hidrofobizasyon kısmında ise Oktadesiltriklorosilan (OTS,%95) kullanılmıştır. Yapılan modifikasyon uygulamalarının karakterizasyonunda Fourier dönüşümü kızılötesi spektroskopisi (FTIR), Taramalı elektron mikroskopisi (SEM), X-ışını kırınımı (XRD) ve Enerji dağıtıcı x-ışını (EDX) enstrümental analizleri kullanılmıştır. Fonksiyonlanan yeni yüzeyin su temas açısı (WCA) ölçümleri yapılarak hidrofobisitesi belirlenmiştir. Anti-UV özellikliği ise UV-Vis spektrometresi tespit edilmiştir. Yapılan karakterizasyon çalışmaları sonucunda, hidrotermal olarak yapılan nano fonksiyonlandırmanın başarılı olduğu kanıtlanmıştır. Yeni yüzeyin su temas açısı θγ 128° olarak ölçülmüştür. Dalga boyu aralığının 200-800 nm olduğu alanda anti-UV özellik sergilemiştir. Fonksiyonlandırma sonrası yüzey değişim parametreleri ISO 4287 standardına göre yapılmıştır. Renk değişim oranları ise ISO 2469 (2014) standartlarına uygun olarak belirlenmiştir.
