Abstract ZnO is an ideal material for UV detection. However, due to the surface effect of ZnO, the photosensitivity of the ZnO based UV detector needs to be improved. In this study, we deposited a hydroxyl group functionalized (3,4-propylenethiophene) polymer (PProDOT-OH) film onto a hydrothermally grown ZnO nanoarray by electro-chemical deposition method to prevent the corrosion of ZnO by phosphotungsten acid (PWA), and then PWA was drip-coated on the composite film to prepare the ZnO/PProDOT-OH/PWA composite based UV detector. The structure and morphology of the composite were characterized by SEM, UV–vis, FT-IR, XRD, Raman, EDS, XPS analysis, illustrating the phosphotungstic acid was uniformly coated on ZnO/PProDOT-OH surface and confirming the composite was successfully synthesized. The UV detection performance was studied through preparing a UV detector with the composite material and results indicate that the introduction of PWA could enhance the responsivity of the ZnO/PProDOT-OH composite-based UV detector.

用于紫外检测器的氧化锌/聚合物/磷钨酸复合材料的电化学合成

摘要 ZnO是一种理想的紫外检测材料。然而，由于ZnO的表面效应，基于ZnO的紫外检测器的光敏性有待提高。在这项研究中，我们通过电化学沉积方法在水热生长的 ZnO 纳米阵列上沉积了羟基官能化的 (3,4-丙烯噻吩) 聚合物 (PProDOT-OH) 薄膜，以防止磷钨酸 (PWA) 对 ZnO 的腐蚀，以及然后将PWA滴涂在复合薄膜上，制备出基于ZnO/PProDOT-OH/PWA复合材料的紫外检测器。通过SEM、UV-vis、FT-IR、XRD、Raman、EDS、XPS分析对复合材料的结构和形貌进行了表征，表明磷钨酸均匀地包覆在ZnO/PProDOT-OH表面，证实复合材料成功合成.
