摘　　要：为赋予锦纶织物近红外光隐身功能,在十二烷基苯磺酸钠(SDBS)的辅助下,以纤维素纳米晶须(CeNW)作为分散剂,液相剥离石墨粉制备稳定的石墨烯水分散液(SCG),协同酸性染料上染锦纶织物。对所制备织物热稳定性、Zeta电位、电导率、微观形貌、反射率、颜色特征及色牢度进行了表征。结果表明:当SDBS质量浓度为0.5 mg/mL,且石墨粉与CeNW质量比为1∶2时,SCG分散性最佳,石墨烯质量分数达18.5%;上染后的锦纶织物在可见光范围内K/S值高,显示了良好的染色效果;近红外光范围内的反射率从33%降到29%,实现了锦纶织物的近红外光隐身功能。Objective The requirements for infrared camouflage in modern warfare are becoming increasingly complex and challenging.In order to provide effective camouflage in the visible and infrared spectral ranges,it is necessary to develop suitable infrared camouflage equipment,of which the most effective method is to develop infrared camouflage materials.Near-infrared camouflage textile materials are usually combined with visible light camouflage in the form of camou-flage fabrics.Method In this research,acid dyes and cellulose nanowhisker liquid-phase stripped graphene were used to syn-ergistically top-dye nylon fabrics to achieve the stealth effect of the fabrics in the visible/near-infrared light bands,aiming to effectively reduces the risk of being detected by the reconnaissance system,and to significantly improve the covertness and survivability of military equipment.Results A stable graphene aqueous dispersion(SDBS-CeNW-Graphene,abbreviated as SCG)was prepared by liquid-phase exfoliation of graphene with CeNW as the dispersant with the assistance of the small-molecule surfactant SDBS,which showed remarkable dispersion stability in aqueous solution,and there was no obvious precipitation within three months of standing.When the concentration of SDBS reached 0.5 mg/mL,the surface tension of SCG dispersion did not decrease significantly,and the concentration of SCG was close to the critical micelle concentration CMC,when the surface tension reached the minimum.The dispersion effect of SCG dispersions was best when the ratio of graphene to CeNW was 1∶2.Using SCG dispersion to synergize with acid dyes for dyeing nylon fabrics showed high K/S values in the visible light range,which proved the excellent dyeing effect;while in the near-infrared light range,the reflectivity decreased from 33%to 29%,successfully achieving the near-infrared light stealth function of nylon fabrics.Conclusion In this study,the feasibility of near-infrared light stealth nylon fabrics prepared by liquid-phase exfoliation of graphene from cellulo
