From: Towards conductive textiles: coating polymeric fibres with graphene
(a) Photo of the fibres in reels, left to right: PP2, PE, PLA2 (left) and of the fibres cut to ca. 3 cm length, left to right: PP1, PLA1, PP2, PLA2, PE (right). (b) Sheet resistance as a function of bending radius for samples of each coated fibre. In-plane measurements were performed before and after the bending cycle (“flat” in the x-axis). (c) Distribution of sheet resistance values for several coated samples of each fibre. (d) Transmittance as a function of wavelength for bare PP2 and PE, and graphene-coated (+G) PP2 and PE fibres. Insets show detail of transmittance for PP2 and PE. (e) Raman spectra of the bare fibres and graphene-coated (+G) fibres. Vertical dashed lines at 1345, 1685 and 2685 cm−1 correspond to the D, G and 2D peak positions, respectively.
