【摘要】 以玫瑰花瓣为模板,通过复制制备出具有正负两种花瓣表面微纳结构的PDMS基底,在PDMS基底上化学生长ZnO纳米结构。通过控制生长条件(前驱体浓度、反应时间等),可对在PDMS玫瑰花瓣表面结构上生长ZnO纳米结构的尺寸和形貌进行有效控制。发现PDMS基底上生长ZnO纳米结构,其表面具有超疏水性质。组装光电器件进行测试,发现其对紫外光具有明显的响应,可用于制作具有柔性和自清洁效应的紫外光探测器更多还原

【Abstract】 Positive and negative surface structures on PDMS were replicated with natural rose petals as template. ZnO nanostructures were fabricated on these micro/nano structures of PDMS substrate by wet chemistry method. By altering the growth conditions(precursor concentration, reaction time, etc.), we effectively controlled the size and morphology of the ZnO nanostructures on the PDMS substrate. We compared the structures and surface wettability with natural rose petal and found that the growth of ZnO nanostructures on the PDMS substrate could improve its hydrophobicity. More importantly, obvious response to UV light was found on ZnO/PDMS sample after assembled into UV photodetector. It showed potential application in flexible UV detectors with self-cleaning effect.更多还原
