Preparation and Photo-thermal Performance Analysis of Graphene Carbon Based Photo-thermal Regenerated Cellulose Fibers
Graphene dispersion system was prepared as a photo-thermal functional agent,and was then added into the spinning solution of regenerated cellulose fiber through the pre-spinning injection device,and the carbon based graphene photo-thermal functional regenerated cellulose fiber was prepared by the wet spinning process.The preparation method of graphene dispersion system was introduced,and the photo-thermal function of the prepared graphene carbon based photo-thermal regenerated cellulose fiber was analyzed.The results show that the prepared graphene dispersion system has small particle size and particle size distribution,the dispersion effect is good,and the carbon based graphene photo-thermal regenerated cellulose fiber has good photo-thermal function.The surface temperature of the fiber increases with the increase of infrared irradiation time and the addition of graphene.After removing infrared radiation,the rate of temperature declines gradually with the increase of graphene addition.The fiber has high absorbability to light within the test wavelength range,excellent far-infrared performance,and the optical thermal storage performance,far-infrared performance and thermal conductivity gradually increase with the increase of graphene.
