In the field of LEDs, solar cells, and FETs, the uniaxially aligned semiconducting polymer films have been widely investigated to improve their electric and optical properties. but, time-consuming process, and low crystallinity were still pointed out as limitations. So by using Eutectic Friction Transfer, we have enhanced electrical properties by aligning semiconducting polymer uniaxially with very convenient way in few seconds. during the process, friction induced heat caused regional melting on the interface of eutectic pellet and substrate, at the same time shearing force transformed semi-conducting polymer from entangled structure to uni-directional aligned structure. consequentially, Eutectic Friction Transferred semiconducting polymer had a high crystallinity like single crystal and high electrical properties. and by overcoming time-consuming problems and difficulties in mass production, EFT method open ups the new possibility of device application for semiconducting polymer. |
