(a) FT-IR spectra of the uncross-linked fiber indicated by S (PEO/CH) and cross-linked fibers: at 0.3% v/v GTA, GNP, and TPP, respectively. (b) FT-IR spectra of the cross-linked fibers: at 0.1, 0.2, 0.3, and 0.4% v/v GNP. (c) FT-IR spectra of the GNP cross-linked fibers upon UVA irradiation: at 0.1, 0.2, 0.3, 0.4, and 0.5% v/v GNP.
