摘要
在织物表面构建导电通路对纺织智能可穿戴用品具有重要意义。以聚酰胺-6(PA-6)织物为基材,SnCl2为敏化剂对织物进行改性处理,以银氨溶液作为导电墨水,通过浸渍法在PA-6织物表面制备了纳米银导电层,得到导电织物PA-6。利用扫描电子显微镜、X射线光电子能谱仪和X射线衍射仪对样品进行表征分析,同时结合 MATLAB图像处理技术定量分析纳米银在织物表面的覆盖率,考察了试剂用量和工艺参数对纳米银层形成的影响。结果表明:SnCl2质量浓度从0g/L增加至25g/L时,纳米银覆盖率从30.56%提升至72.32%,并且纳米银颗粒尺寸增大;质量浓度2g/L的盐酸可有效抑制SnCl2水解;在敏化过程中,水洗3次后PA-6织物表面纳米银层达到较好的均匀度;葡萄糖质量分数由3%增加至15%时,纳米银覆盖率从45.15%增加至74.7%,纳米银层体积电阻率最小为 4×10-6Ω·m。
Abstract
Constructing conductive pathways on fabric surfaces is of great significance for textile-based smart wearable products.Using PA-6 fabric as the substrate and SnCl2 as the sensitizer,the fabric was modified.A silver ammonia solution was used as the conductive ink,and a nano-silver conductive layer was prepared on the PA-6 fabric surface via the dipping method,resulting in the conductive fabric PA-6.The samples were characterized and analyzed using scanning electron microscopy,X-ray photoelectron spectroscopy,and X-ray diffraction.Combined with MATLAB image processing technology,the coverage of nano-silver on the fabric surface was quantitatively analyzed,and the effects of reagent dosage and process parameters on the formation of the nano-silver layer were investigated.The results showed that when the mass concentration of SnCl2 increased from 0g/L to 25g/L,the nano-silver coverage increased from 30.56% to 72.32%,and the particle size of the nano-silver increased.A hydrochloric acid mass concentration of 2g/L effectively inhibited the hydrolysis of SnCl2.During the sensitization process,the nano-silver layer on the PA-6 fabric surface achieved better uniformity after three water-washing cycles.When the mass fraction of glucose increased from 3% to 15%,the nano-silver coverage increased from 45.15% to 74.7%,and the minimum volume resistivity of the nano-silver layer was 4×10-6Ω·m.
