co2 adsorption of pet fabric coated with graphene oxide

In this work the co2 adsorption of polyethylene terephthalate (pet) nonwoven fabric was improved by graphene oxide (go) coating on the fabric. the go-coated fabrics prepared by immersing the nonwoven fabric into the graphene oxide dispersion (1,5 mg/ml) and then drying at 70 °c for three times. the sem and ftir investigations confirmed the go coating on pet fabric (go-pet). the results showed that co2 adsorption of go-pet improved by 15.3% and 140%  comparing to the pet and go, respectively. the results demonstrated that the porosity of fabric and go functional groups are effective factors on the co2 adsorption of the go-coated fabric.
