В настоящем исследовании представлен синтез нанотрубок TiO₂ с использованием комбинированного гидротермального и ультразвукового подходов с короткими выдержками от 4 до 10 ч для оценки управляемости морфологии и кристаллической структуры для антикоррозионных приложений. Ультразвуковая предподготовка улучшала диспергирование прекурсора и способствовала формированию упорядоченных нанотрубчатых структур, сокращая время синтеза по сравнению с традиционными методами. Полученные материалы были исследованы с помощью сканирующей электронной микроскопии (СЭМ) для анализа морфологии и распределения нанотрубок, спектроскопии Рамана и рентгеноструктурного анализа (РСА) для оценки фазового состава и кристалличности, а также инфракрасной спектроскопии с преобразованием Фурье (ИК-Фурье) для изучения поверхностных связей. Результаты показали различия в организации нанотрубок, кристалличности и фазовом развитии в зависимости от времени реакции, подтверждая ключевую роль длительности синтеза в формировании структурных параметров. Рассматриваемый гибридный метод представляет собой эффективную стратегию синтеза функциональных наноматериалов с улучшенной способностью к хранению и контролируемому высвобождению ингибиторов коррозии в полимерных покрывных системах.

This study presents the synthesis of TiO2 nanotubes using a combined hydrothermal–ultrasonic approach with short hydrothermal durations ranging from 4 to 10 hours, aiming to evaluate the controllability of morphology and crystalline structure for anticorrosion applications. Ultrasonic pretreatment was applied to enhance precursor dispersion and promote the formation of ordered nanotubular structures, thereby reducing synthesis time compared with conventional hydrothermal processes. The obtained materials were characterized using several complementary techniques: scanning electron microscopy (SEM) to analyze morphology and nanotube distribution, Raman spectroscopy and X-ray diffraction (XRD) to assess phase composition and crystallinity, and Fourier-transform infrared spectroscopy (FTIR) to identify surface bonding features. The results revealed apparent differences in nanotube organization, crystallinity, and phase development depending on the reaction duration, confirming that synthesis time plays a decisive role in tailoring structural parameters. These findings demonstrate that the hydrothermal–ultrasonic method provides an efficient and versatile route for fabricating TiO2 nanotubes with tunable structural and functional properties. Furthermore, the synthesized nanostructures exhibit strong potential as carriers of corrosion inhibitors, enabling improved storage and controlled release within polymer-based protective coatings, thereby contributing to the development of next-generation anticorrosion technologies.
