Fig. S3a High resolution XPS C1s showed binding energies. The peaks at 285 eV, 286.5 eV and

288-289 eV are derived from C–C, C-S/C-O and C=C bonds in PEDOT. The peaks at 292 eV and

294 eV for PEDOT/FAS and PEDOT/FD-POSS/FAS coated surface are typical characteristic of

CF2 and CF3 moieties.

For PEDOT coated fabric, the appearance of vibration peaks at 1506 and 1473 cm–1 was attributed

to the stretching modes of C=C and C–C in the thiophene ring. The vibration of the C–S bond in the

thiophene ring can be observed at 848 cm–1. The peak at 970 cm–1 was due to the ethylenedioxy

ring deformation [S. V. Selvaganesh, J. Mathiyarasu, K. L. N. Phani, V. Yegnaraman, Nanoscale

Research Letter, 2007, 2, 546-549]. For the PEDOT coating containing FD-POSS/FAS or FAS in

the coating layer, peaks at 1200 cm-1 and 1147 cm-1 occurred in the spectra, which were the typical

characteristics of C–F and Si–O–Si vibrations, respectively.
