Abstract
MXenes have emerged as a highly versatile class of two-dimensional materials with exceptional electrical conductivity, flexibility, and hydrophilicity. Integrating MXene with polymers has unlocked extensive opportunities for various applications. This review discusses the preparation methods of MXenes and their polymer composites and critically analyzes the structure-property relationships that govern their performance in sensors, supercapacitors, and electromagnetic interference shielding. The potential of these composites in biomedical and other cutting-edge applications is also explained. Additionally, the role of emerging tools, such as machine learning and density functional theory calculations, is highlighted as promising approaches for accelerating the development and application directions of MXenes and their composites. Furthermore, this review discusses the associated challenges and offers future perspectives for advancing the potential of these materials. Overall, this review aims to critically summarize existing efforts and provide a platform for researchers seeking to develop high-performance MXene/polymer composites.
