Patent Landscape Review of MXene Composites for Advanced Functional Materials

MXene composites represent an exceptionally promising member of the family of two-dimensional multifunctional materials known for outstanding electrical properties, mechanical strength, chemical tuning abilities, and the potential for wide applications. The paper conducts a profound patent landscape investigation of MXene composites with the help of the WIPO PATENTSCOPE database. In total, 658 patent families were found; duplicate patent entries were eliminated through the application of the Single Family Member method. The results show that China is a patent leader worldwide, followed by PCT applications and the patenting activity of the USA, India, and other countries, which indicates a growing international interest in MXene technologies and materials. The classification of patents also shows that this technology is actively researched in relation to the development of technologies in the field of electrochemical energy storage, polymer engineering, sensing technologies, catalysis, environmental remediation, electronics, and biomedical applications. Additionally, the paper studies the technology development in the field of the creation of MXene antennas, semiconductor devices, and ceramic oxide composites, materials that change shape, anti-corrosion coatings, electrochemical sensors, and many others. Even though substantial advances have been made, obstacles related to efficient manufacturing, oxidation resistance, quality assurance, sustainability, and industry adoption persist. The overall picture of patents shows that MXene-based composite materials have progressed from the testing stage to commercial products with high potential for next-generation technologies.
