FTIR spectra of the carbonyl (C=O) groups of TNTs/GO-PVC film versus UV irradiation time (a) and before and after photodegradation (b). The intensity of the C=O absorption peak of TNTs/GO-PVC film increases continually with increasing irradiation time; it is more pronounced than that for neat PVC film and for TNTs-PVC film. This further demonstrates that the TNTs/GO nano-filler can indeed promote the photo-oxidation reaction of the PVC matrix
