The interfacial polycondensation of titanium dioxide was studied at the bare and fiberglass membrane supported polarized liquid-liquid interface (LLI). Titanium dioxide synthesis was derived from the titanium (IV) tetrabutoxide (initially dissolved in the 1,2-dichloroethane) interfacial hydrolysis followed by its condensation. Experimental parameters, such as the pH of the aqueous phase and the influence of titanium alkoxide concentration in the organic phase on the electrochemical signal and material morphology, were investigated. The latter was achieved with fiberglass membranes used as the LLI support during TiO interfacial deposition. Cyclic voltammetry was used for the in situ studies, whereas scanning electron microscopy, energy-dispersive X-ray spectroscopy, and infrared spectroscopy were used during ex situ examination. The interfacial polycondensation reaction could be studied using electrified LLI and resulted in the material being a TiO film alone or film decorated with particles.
在裸露的和玻璃纤维膜支撑的极化液-液界面（LLI）上研究了二氧化钛的界面缩聚反应。二氧化钛的合成源于四丁氧基钛（IV）（最初溶解于1,2-二氯乙烷中）的界面水解及其缩合反应。研究了实验参数，如水相的pH值以及有机相中钛醇盐浓度对电化学信号和材料形态的影响。后者是通过在TiO界面沉积过程中使用玻璃纤维膜作为LLI支撑体来实现的。循环伏安法用于原位研究，而扫描电子显微镜、能量色散X射线光谱和红外光谱则用于非原位检测。可以使用带电的LLI研究界面缩聚反应，反应结果是材料为单独的TiO薄膜或带有颗粒的薄膜。
