ABSTRACT
Polyimide is one of the most high-performance and effective engineering polymers with excellent mechanical, thermal, dielectric, and chemical stability characteristics. However, its further improvement with nanofiller incorporation is of great importance in broadening its candidature for engineering applications. Thus, the review focused on the role of TiO2 nanoparticles on the mechanical, tribological, thermal, permeability, and dielectric performance of polyimide-based nanocomposites. Herein, it is worth knowing that TiO2 is a promising reinforcement material for improving polyimide nanocomposites for advanced engineering applications. Additionally, the authors concluded the study with challenges and recommendations for further improvement of TiO2/polyimide-based nanocomposite characteristics for high-tech fields.
