An international research team has synthesized a multilayered two-dimensional polyaniline (2DPANI) crystal, achieving unique metallic out-of-plane charge transport and high conductivity. This study was published in Nature.
Conducting polymers, such as polyaniline, polythiophene, and polypyrrole, are renowned for their electrical conductivity and have significant potential as low-cost, lightweight, and flexible alternatives to traditional semiconductors and metals.
However, efficient charge transport, particularly between polymer chains, has been a critical challenge, thereby limiting the performance and practical applications of conducting polymers.
In response to this challenge, researchers from the Ningbo Institute of Materials Technology and Engineering (NIMTE) of the Chinese Academy of Sciences (CAS), TU Dresden, the Max Planck Institute of Microstructure Physics, and CIC nanoGUNE BRTA have developed a novel 2DPANI crystal by virtue of a topology-directed 2D polymerization of aniline using an anionic surfactant monolayer on the water surface.
