Abstract

The aim of this study is to investigate the effect of isopropyl triisostearoyl titanate (KR-TTS) as a titanate coupling agent (TCA) on surface modification of TiO2 nanotube (TNT) material. From the physical and chemical studies that have been performed on the modified TiO2 nanotube, scanning electron microscope micrographs, energy-dispersive X-ray and viscosity indicated that there was significant reduction in particle aggregation of the modified TiO2 Nanotube. FTIR spectroscopy confirmed that the functional group of the TCA reacted with the hydroxyl groups present on the surface of TiO2 nanotube resulting in an altered surface property from being hydrophilic to hydrophobic. X-ray diffraction indicated that crystalline structure did not change upon the modification with the coupling agent. Isopropyl triisostearoyl titanate (KR-TTS) is found to be superior in performance and has a significant effect on the dispersion and resolving of agglomeration. This paper presents the effect of surface modification with the TCA of isopropyl triisostearoyl titanate (KR-TTS) type on the TiO2 nanotube material.

钛酸异丙基三异硬脂酸酯(KR-TTS)处理TiO2纳米管的理化研究

本研究的目的是研究钛酸异丙基三异硬脂酸酯(KR-TTS)作为钛酸偶联剂(TCA)对TiO2纳米管(TNT)材料表面改性的影响。通过对改性后的TiO2纳米管进行的物理和化学研究、扫描电镜、能量色散x射线和粘度的研究表明，改性后的TiO2纳米管的颗粒聚集明显减少。FTIR光谱证实，TCA的官能团与TiO2纳米管表面的羟基发生反应，导致其表面性质由亲水性变为疏水性。x射线衍射表明，偶联剂对其进行改性后，晶体结构没有发生变化。钛酸三异硬脂酸异丙酯(KR-TTS)性能优越，对团聚体的分散和溶解有显著影响。本文研究了钛酸异丙基三异硬脂酰钛酸酯(KR-TTS)型TCA对TiO2纳米管材料表面改性的影响。
