•Bacterial cellulose (BC) films and composites of BC with PEDOT/PSS are studied.•Terahertz time domain spectroscopy in the spectral range 0.3–2.8 THz is applied.•Refractive index, extinction coefficient, dielectric permittivity spectra are obtained.•Increase in the imaginary part of dielectric permittivity of BC:PEDOT/PSS is found.
Terahertz response of free standing films of bacterial cellulose and its composites with conducting polymer complex PEDOT/PSS has been studied by terahertz time domain spectroscopy. Spectra of refractive index, extinction coefficient and complex dielectric permittivity are obtained in spectral range of 0.3–2.8 THz for both types of cellulose films. Considerable increase in the imaginary part of dielectric permittivity of bacterial cellulose films modified with a conductive polymer complex PEDOT/PSS as compared to that of pristine bacterial cellulose film was found out.
