Microwave-assisted One-step Degumming and Modification of Hemp Fiber with Graphene Oxide

Abstract

Microwave-assisted one-step degumming and modification of hemp fiber with graphene oxide (GO) have been studied. The results showed that the residual gum content of the hemp using GO bath is lower than that obtained using water bath, and the hemp fiber possessed electrical conductivity, better breaking strength, thermal conductivity, and good UV protection ability. Raman spectrum indicated that GO turned into reduced graphene oxide during the degumming process, and it was found on the surface of the fibers seen from SEM images. One-step degumming, reduction of GO, and modification of hemp fiber can be achieved with the microwave-assisting.
