摘　　要：为拓展二维过渡金属碳化物(MXene)在纺织品中的应用,基于LiF/HCl选择性刻蚀作用原理,以Ti_(3)AlC_(2)为前驱体,制备出二维纳米材料Ti_(3)C_(2)T_(x)。借助透射电子显微镜、扫描电子显微镜、X射线能谱衍射仪、紫外-可见吸收光谱仪等对Ti_(3)C_(2)T_(x)表面形貌、结构、化学组成进行表征。采用浸轧-预烘-焙烘工艺将Ti_(3)C_(2)T_(x)整理到织物上,优化了整理工艺,并研究了织物的防紫外线及导电性能。结果表明:当Ti_(3)C_(2)T_(x)质量浓度为8 g/L,轧余率为100%,浸渍40 min,150℃焙烘3 min时,经过4次重复整理后,织物表面电阻达到最低值0.602 kΩ/□,此时Ti_(3)C_(2)T_(x)质量分数为1.25%;经过数次整理的织物有极好的防紫外线性能,紫外线防护系数达到500;整理后织物能保持良好的透气性,整理5次的织物经过20次水洗后表面电阻低于5 kΩ/□。To study the application of textiles,a two-dimensional nanomaterial Ti_(3)C_(2)T_(x)was prepared using Ti_(3)AlC_(2) as the precursor based on the selective etching of LiF/HCl.Transmission electron microscope,scanning electron microscope,X-ray energy spectrum diffraction,ultraviolet-visible absorption spectrum were used to characterize the surface morphology,structure,chemical composition of Ti_(3)C_(2)T_(x),which was used to treat cotton knitted fabrics using the pad-dry-cure technique with optimised finishing technic parameters.The results show that under the condition that the concentration of Ti_(3)C_(2)T_(x)was 8 g/L,the liquid ratio was 100%,the dipping time was 40 min,the baking temperature was 150℃,baking time was 3 min and repeated 4 times,the fabric had the best conductivity with 1.25%Ti_(3)C_(2)T_(x)loading.Ti_(3)C_(2)T_(x)is uniformly distributed on the surface of the fabric,and the surface resistance is significantly reduced to 600Ω/□.The fabric after several finishing has excellent UV resistance,and the ultraviolet protection value reaches 500.The finished fabric presents good breathability,and the surface resistance of the finished fabric is lower than 5 kΩ/□after 5 times of finishing under 20 times of washing.
