Abstract

Well aligned ZnO nanowire (NW) arrays are grown on Kevlar fiber and Kapton film via the chemical vapor deposition (CVD) method. These NWs have better crystallinity than those synthesized through the low-temperature hydrothermal method. The average length and diameter of ZnO NWs grown on Kevlar fiber can be controlled from 0.5 to 2.76 μm and 30 to 300 nm, respectively. A flexible ultraviolet (UV) sensor based on Kevlar fiber/ZnO NWs hybrid structure is made to detect UV illumination quantificationally.

摘要

通过化学气相沉积（CVD）方法，在 Kevlar 纤维和 Kapton 薄膜上生长出排列整齐的 ZnO 纳米线（NW）阵列。这些 NW 的结晶性优于通过低温水热法合成的 NW。在 Kevlar 纤维上生长的 ZnO NW 的平均长度和直径可分别控制在 0.5 至 2.76μm 和 30 至 300nm 范围内。制作了基于 Kevlar 纤维/ZnO NW 杂化结构的柔性紫外（UV）传感器，用于定量检测 UV 光照。
