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.

摘要

研究了微波辅助氧化石墨烯(GO)对大麻纤维的一步脱胶改性. 结果表明，氧化石墨烯浴法与水浴法相比，大麻纤维的残胶含量较低，且大麻纤维具有导电性、较好的断裂强度、导热性和良好的防紫外线能力. 拉曼光谱表明，在脱胶过程中，GO转变为还原氧化石墨烯(rGO)，并在SEM图像中发现其存在于纤维表面. 微波辅助一步脱胶、还原氧化石墨烯和改性大麻纤维.
