摘要:
本文以纯棉织物作为柔性基体,首先在纯棉织物表面涂覆聚多巴胺(PDA)/MXene,然后在其表面通过无电沉积的方法沉积具有粗糙结构的金属铜(Cu),得到一种具有导电性和抗菌性的PDA/MXene/Cu改性棉织物。采用扫描电子显微镜对棉织物的形貌进行观察,通过万能试验拉伸机测量棉织物的力学性能。结果表明:Cu、PDA和MXene均匀覆盖在棉织物表面。PDA/MXene/Cu改性棉织物的力学性能提升,改性棉织物的拉伸强度和断裂伸长率分别增长到了150 kPa和28.6%。进一步将导电棉织物作为应变传感器监测人体手指的弯曲情况从而对器件的传感性能进行评价,当手指弯曲角度为60°时最大传感响应为10.9%。最后对导电棉织物进行抗菌测试,测试结果表明改性棉织物具有良好的抗菌性能,在沉积铜1.5 h时抑菌圈直径为31.8 mm、面积为793.9 mm2。这种多功能PDA//MXene/Cu改性棉织物,有望应用在可穿戴电子设备、健康和运动监测器等领域。

Abstract:
Pure cotton fabric was used as a flexible matrix, and firstly,polydopamine (PDA)/MXene was coated on the surface of pure cotton fabric,and then rough structured metal copper (Cu) was deposited on its surface by non electrodeposition method to obtain a PDA/MXene/Cu-modified cotton fabric with conductivity and antibacterial properties. The morphology of cotton fabric was observed using a scanning electron microscope,and the mechanical properties of cotton fabric were measured using a universal tensile testing machine. The results showed that Cu,PDA,and MXene uniformly covered the surface of cotton fabric. The mechanical properties of PDA/MXene/Cu-modified cotton fabric were improved,and the tensile strength and elongation at break of the modified cotton fabric increased to 150 kPa and 28.6%,respectively. Further using conductive cotton fabric as a strain sensor to monitor the bending of human fingers and evaluate the sensing performance of the device,the maximum sensing response was 10.9% when the finger bending angle was 60°. Finally,antibacterial tests were conducted on the conductive cotton fabrics,and the results showed that the modified cotton fabric had good antibacterial properties. When copper was deposited for 1.5 hours,the diameter of the antibacterial ring was 31.8 mm and the area was 793.9 mm2. This multifunctional PDA/MXene/Cu-modified cotton fabric is expected to be applied in wearable electronic devices, health and motion monitors, and other fields.
