Side Chain Engineering of Polymer Semiconductor for Advancing Colloid Compatibility |
| 초록 |
We introduce synthetic approach to enhance coalescence phenomenon during solidification of water-borne colloids so that thin, even, and continuous film morphology of polymer semiconductors can be realized. From theoretical study of complex colloids, we show that small-sized and uniform colloid particles are essential to minimize depletion energy between colloid particles and thus to enhance coalescence. Therefore, the newly synthesized polymer semiconductor is designed with the aim of better molecular affinity with surfactants, so that phase transfer of polymer semiconductors from organic phase to water phase can proceed more efficiently during mini-emulsion synthesis. Such a molecular tuning increases the volumetric portion of hydrophobic alkyl chains and thus enables higher solubility as well as higher hydrophobicity. As a result, it is shown that the performance of water-borne colloids-based devices can be improved to a level similar to the case of organic solvents-based devices. |
