摘　　要：制备石墨烯分散体系作为光热功能助剂,并通过纺前注射装置将其加入再生纤维素纤维纺丝溶液中,采用湿法纺丝工艺制备石墨烯碳基光热功能再生纤维素纤维。介绍石墨烯分散体系的制备方法,并对制备的石墨烯碳基光热功能再生纤维素纤维的光热性能进行分析。结果表明:制备石墨烯分散体系具有较小的粒径和粒径分布,且分散效果良好;石墨烯碳基光热功能再生纤维素纤维具有较好的光热功能,该纤维表面温度随红外辐照时间增加和石墨烯添加量增加而逐渐升高;去除红外辐照后,温度下降速率随石墨烯添加量增加而逐步减小;该纤维对测试波长范围内的光均具有较高吸收性,远红外性能优良,远红外性能和导热系数随石墨烯增加而逐渐增大。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.
