An eutectic friction transfer (EFT) is based on the eutectic melting by frictional heating at the interface between the pellet made of semiconducting polymer/matrix mixture and the substrate. The semiconducting polymer chains can be uniaxially aligned and crystallized by the frictional shear force. Futher, we combined eutectic friction transfer with charge-transfer doping. The uniaxially aligned P3HTEFT film was obtained from the eutectic friction transfer method, and F4TCNQ-doping was conducted to the P3HTEFT film. F4TCNQ-doped P3HTEFT film shows highly anisotropic characteristics. P3HT polarons are uniaxially aligned along the P3HT chains, and F4TCNQ anions are perpendicularly located to the P3HT polarons. The F4TCNQ-doped P3HTEFT film was analyzed by polarized UV-vis and IR spectrometer.
