摘　　要：本研究以聚酯织物作为基材,利用辐射固化和化学镀铜方法制备织物基柔性电路。探讨了柔性电路的微观形貌、元素分布、耐久性及稳定性。实验采用工业级电子加速器配合具有电路结构的钢板“胶片”模具实现电子束选择性辐照,进而在织物上形成与设计电路图完全对应的涂料固化区(含Ag/Fe_(3)O_(4)催化剂),再通过化学镀原位沉积金属层构建织物基柔性电路。扫描电子显微镜(SEM)、能谱元素分析(EDS)和X射线衍射(XRD)结果表明:制备的织物柔性电路结构清晰,导电铜层结晶性高。织物基柔性电路在弯折测试15 000次中,电阻变化率变化低于16%,且在15~55℃的变温实验中电阻变化率未超过5%,说明其具有良好的耐久性和稳定性。本研究的织物基柔性电路为智能织物产品的开发提供了新的研究思路。This study focuses on the preparation of fabric-based flexible circuits using polyester fabric(PET)as a substrate via radiation curing and chemical copper plating methods.The microstructures,elemental distributions,durabilities,and stabilities of the flexible circuits were investigated.In this experiment,an industrial electron accelerator was utilized in conjunction with a steel plate"film"mold containing circuit structures to achieve selective irradiation by electron beams.Consequently,cured coating areas corresponding precisely to the designed circuit diagram(containing Ag/Fe_(3)O_(4) catalyst)were formed on the fabric.Subsequently,metal layers were deposited in situ via chemical plating to construct fabric-based flexible circuits.Scanning electron microscopy(SEM),energy-dispersive X-ray spectroscopy(EDS),and X-ray diffraction(XRD)results demonstrated that the fabricated flexible circuit exhibited a well-defined structure and a highly crystalline conductive copper layer.During a bending test comprising 15000 cycles,the resistance change rate of the fabric-based flexible circuit remained below 16%,whereas during a temperature variation test ranging from 15℃to 55℃,it remained below 5%.These results suggest that the circuit exhibits exceptional durability and stability.The fabrication method for fabric-based flexible circuits presented herin offers novel insights into the development of smart textile products.
