Successful development of a perfect diamagnetic conducting polymer

Researchers have synthesized a conducting polymer, polyaniline, exhibiting perfect diamagnetic properties, which eliminate external magnetic fields within the material. These properties are typically associated with superconductors. While conducting polymers generally display paramagnetism -- where they are weakly attracted to magnetic fields -- this breakthrough marks the first step towards developing a conducting material that demonstrates diamagnetism, the opposite of paramagnetic behavior.
