Ice surface chemistry enabling high-conductivity 2D polymers for optoelectronic devices |
| 초록 |
Air–water interfacial polymerization results in sheetlike 2D polymer revealing exotic features of well-ordered crystallinity, high conductivity and processability. The key to develop free-standing, large-area PEDOT PSS films is presented by rapid polymerization at quasi-liquid layer by self-arranged in-plane propagation of PEDOT-linked PSS chains stabilized by H-bonding. A well-defined stacking order benefits from high conductivity for 2D PEDOT PSS without further treatment. These films are even transferrable to desired substrates by melting of ice that makes 2D polymer electrodes for photoelectrochemical and solar cells. The role of 2D conducting network is disclosed by excellent photocurrent generation and hydrogen evolution by coupling to quantum dots, and by power conversion efficiency of 5.34% polymer solar cell. Ice chemistry thus showcase fabrication of 2D polymers as viable alternate to inorganic 2D counterparts like graphene or MoS2. |
