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.

三异硬脂酰钛酸异丙酯 (KR-TTS) 处理的 TiO2 纳米管的物理和化学研究

本研究的目的是研究三异硬脂酰钛酸异丙酯 (KR-TTS) 作为钛酸酯偶联剂 (TCA) 对 TiO ₂纳米管 (TNT) 材料表面改性的影响。_{根据对改性 TiO 2}纳米管进行的物理和化学研究，扫描电子显微镜显微照片、能量色散 X 射线和粘度表明改性 TiO ₂纳米管的颗粒聚集显着减少。_{FTIR 光谱证实 TCA 的官能团与 TiO 2}表面存在的羟基发生反应纳米管导致表面特性从亲水变为疏水。X射线衍射表明晶体结构在用偶联剂改性后没有改变。发现三异硬脂酰钛酸异丙酯 (KR-TTS) 性能优越，对团聚的分散和解决具有显着效果。本文介绍了用三异硬脂酰钛酸异丙酯 (KR-TTS) 型 TCA 对 TiO ₂纳米管材料进行表面改性的效果。
