New tech delivers high-tech film that blocks electromagnetic interference

Science Daily  November 1, 2018 An international team of researchers (USA – New York University, Drexel University, Yale University, China) has developed and demonstrated spin spray layer‐by‐layer (SSLbL) technique to rapidly assemble Ti3C2Tx MXene‐carbon nanotube composite films for EMI shielding. The technique allows strategic combinations of nanostructured materials and polymers providing a rich platform for developing hierarchical architehttps://onlinelibrary.wiley.com/doi/abs/10.1002/adfm.201803360ctures with desirable cross‐functionalities including controllable transparency, thickness, and conductivity, as well as high stability and flexibility. They demonstrated that the films show high conductivities up to 130 S cm−1 and high specific shielding effectiveness up to 58 187 dB cm2 g−1 and […]
