The photoelectrochemical polymerization (PEP) method is one of the ways to prepare polymer networks under mild operation conditions with environmentally benign processes. In addition, PEP polymers could be easily obtained under illumination of visible light at a room temperature, being attracted to many polymerchemists. The polymerization is initiated by excited sensitizing molecules after irradiation and propagated from the initiative sites for the formation of a conducting polymer layer. After sequential addition of two different monomers such as bis-EDOT and bis-EDOT-TB, resulting bilayers consisting all conducting block copolymers (PEDOT-b-PEDOT-TBs) could be obtained. We present the mechanism of PEP by the careful design of experimental conditions to confirm our assumption. In addition, the layer composition was characterized by several analysis such as SIMS, contact angle measurements, and Raman spectrophotometer. |
