Functional materials are a class of materials that possess specific properties or functions that make them suitable for particular applications in various fields such as electronics, medicine, energy storage, and environmental remediation. These materials are designed to exhibit specific properties such as electrical conductivity, magnetism, thermal conductivity, or optical transparency to serve a particular purpose or function. Functional materials can be synthesized from a variety of substances, including organic polymers, inorganic compounds, and hybrid materials. Researchers in this field aim to develop new materials with enhanced or novel functionalities to address emerging technological challenges and create innovative solutions for various industries.
