Surface-grafting polymers: from chemistry to organic electronics
Surface-grafting polymer, also known as polymer brush, has become an important tool for surface modification or functionalization. The strong covalent bond between the polymer brushes and the surface endow polymer brushes with several unique characteristics: precisely control of surface property by the grafting process, better stability, easier for patterning process and so on. Thus, during the past decades, surface-grafting polymers are gradually playing important roles for the developments of organic electronic devices, such as OFETs, OLEDs, OPVs, and so on. In this article, we will comprehensively review the recent progresses about surface-grafting polymers, including their formation process and the utilization of surface-grafting polymers as functional materials of insulators, conductors and semiconductors in versatile organic electronic devices. Then, we will outlook the promising future of surface-grafting polymers in organic electronics.
