Witryna24 cze 2024 · For example, the organic semiconductor ligands are qualified as electronically active components that enable better charge transport in out-of-plane directions. Enhanced out-of-plane conductivity has recently been demonstrated by incorporating a series of acene compounds. Conductive polymers or, more precisely, intrinsically conducting polymers (ICPs) are organic polymers that conduct electricity. Such compounds may have metallic conductivity or can be semiconductors. The biggest advantage of conductive polymers is their processability, mainly by dispersion. Conductive polymers are generally not thermoplastics, i.e., they are not thermoformable. …
