摘　　要：为实现织物基图案化复合纳米材料矩阵的可控成形,采用纳米银复合导电分散液和织物基底相结合,通过低压紫外光照以及化学处理方法,实现织物表面特定线路的表面能差异化,使导电分散液在织物表面定位附着及铺展成形,并对成形的导电矩阵传感性能及服用性能进行测试。结果表明:通过该方法制备的导电矩阵具有良好的分辨率,在1%、5%、10%、15%应变下都能达到稳定循环,能够灵敏地捕捉到弹尺振动、喉结振动、眨眼、手指弯曲等微小振动的信号,在弯折、扭转和摩擦200次后电阻仍能保持稳定,该方法有望制备高灵敏度可穿戴设备实时监测人体运动信号。Objective Flexible sensor devices based on fabrics have shown wide application prospects in fields such as healthcare and human-computer interaction in recent years due to their excellent bendability,good flexibility,and breathability.However,the roughness of the fabric surface makes it difficult to construct high-precision electrode patterns and structures on its surface.Therefore,using low-pressure ultraviolet light and chemical surface treatment methods,a high-precision and high-sensitivity patterned conductive matrix was constructed on the surface of the fabric.Method By combining nano silver composite conductive dispersion with fabric substrate and using low-pressure ultraviolet light irradiation and chemical treatment methods,the surface energy differentiation of specific parts of the fabric surface is achieved,resulting in differences in hydrophilicity and hydrophobicity.This leads to the positioning,attachment,and spreading of the conductive dispersion on the fabric surface.The positioning,adhesion,and spreading of conductive dispersion on the substrate surface were regulated through microstructure morphology construction and surface chemical structure,thereby achieving specific conductive circuit patterns on non-planar substrates.Results To improve the sensitivity and stability of conductive dispersion in sensing applications,silver nanowires were prepared using the polyol method,and carbon nanofibers were introduced to prepare a highly sensitive sensing nano silver composite conductive dispersion.Preparation of high aspect ratio silver nanowires by adjusting silver ion concentration and high-temperature reaction time.Through the synergistic effect between silver nanowires and carbon nanofibers,high aspect ratio silver nanowires were used as the conductive skeleton,and brittle carbon nanofibers are introduced as the"weak link".When the base fabric was stretched,the brittle carbon nanofibers would be shifted first,causing a change in resistance and improving the sensitivity of the conductive network.In or
