![عکس صفحه اول مقاله: Surface grafting of electrochemically crosslinked poly(3,4-ethylenedioxythiophene) (PEDOT) brushes via surface-initiated ring-opening metathesis polymerization Surface grafting of electrochemically crosslinked poly(3,4-ethylenedioxythiophene) (PEDOT) brushes via surface-initiated ring-opening metathesis polymerization](/preview/png/1400620.png)
Herein we demonstrated the preparation of 3,4-ethylenedioxythiophene (EDOT) containing polynorbornylene brushes on Au surfaces via surface-initiated ring-opening metathesis polymerization (SI-ROMP). Using solid-state oxidative crosslinking technique, these polymer brushes were electrochemically converted to conjugated polymer networks. Grazing-angle FTIR spectra of polymer brushes clearly showed the characteristic vibrations of EDOT and norbornylene groups. Furthermore, densely covered Au substrates with polynorbornylene brushes were characterized by using scanning electron microscopy and atomic force microscopy.
Polynorbornylene brushes containing 3,4-ethylenedioxythiophene (EDOT) pendant moieties on gold surfaces were prepared via surface-initiated ring opening metathesis polymerization (SI-ROMP). Tethered EDOT and norbornylene groups on a Au surface were clearly identified from grazing-angle FTIR spectra. These polymer brushes were electrochemically converted to conjugated polymer networks using solid-state oxidative crosslinking technique. Furthermore, the polynorbornylene brushes densely covered the gold substrates which were microscopically characterized by SEM and AFM.Figure optionsDownload as PowerPoint slideHighlights
