Anti-dripping fabrics of polyethylene terephthalate coated with graphene oxide

Polyethylene terephthalate (PET) fabrics were coated with the coupling agent 3-glycidyloxypropyltrimethoxysilane and graphene oxide (GO) by conventional pad-dry-cure processing method. The coated PET fabrics burnt without the melting state and formed the denser and tighter char directly during the combustion. In order to explain the restraining effect of GO, the structure and thermal stability of the coated PET fabrics, the structure of the forming char after vertical burning test were discussed. The morphology images showed that GO formed the uniform film on the entire fabric surface and infrared spectra indicated the successful fabrication of GO on PET fabric by the presence of the peaks at 3420 cm-1 and 1732 cm-1. While the thermal stability changed slightly with coating and XPS analysis illustrated that the ratio of C/O decreased and the function group C = O increased. It can be shown that the addition of GO played the physical role in the dripping resistance of coated PET fabrics.
