A research team led by Dr. Seon Joon Kim from the Korea Institute of Science and Technology (KIST) has published research results in the journal Advanced Materials, successfully developing an amphiphilic MXene material with high conductivity. This material enables stable dispersion in aqueous, polar, and non-polar organic solvents, solving the solvent compatibility issues of two-dimensional nanomaterials in practical applications.

The researchers introduced alkoxide organic monomers onto the MXene surface through surface modification technology, endowing it with both hydrophilic and hydrophobic properties. This amphiphilic characteristic allows MXene to be uniformly dispersed in various polar solvents ranging from water to toluene, significantly improving its compatibility with polymer composites and ink processes. Experiments showed that the material maintains excellent electromagnetic interference shielding performance in the 28GHz frequency band, with a shielding effectiveness exceeding 50dB for a 0.01mm thick film.

Dr. Seon Joon Kim stated: "This achievement proves that MXene materials can be directly applied in industrial on-site processes and represents a major breakthrough from current laboratory-scale technology." The material can be uniformly coated on copper and aluminum current collectors as well as polymer substrates such as polyimide, PET, and Teflon, providing new solutions for secondary battery electrodes and functional coatings.

The research team is collaborating with domestic and international companies to advance mass production technology development. This amphiphilic MXene material has broad application prospects in fields such as electromagnetic shielding for autonomous driving, secondary battery electrodes, and radio wave absorption composites, and is expected to accelerate the commercialization process of next-generation electronic devices.
