摘要
报道了一种基于原位聚合和光刻技术相结合的方法,在聚对苯二甲酸乙二醇酯表面构筑聚苯胺(PANI)纳米纤维阵列微观图案。结果表明,该方法所制备的PANI涂层具有大面积、均一的纳米纤维阵列结构;与滴涂成膜相比,原位聚合方法获得的微米级图案结构具有更高的精度和基底结合能力;同时,基于原位聚合的PANI全塑料湿度传感器件,在湿度传感方面具有更好的重复性和稳定性。
Polyaniline nanofiber coating possesses antistatic properties,electromagnetic shielding,gas sensing,and etc,thus it is of great significance for improving product performance to construct large-area polyaniline nanofiber interface with controlled morphologies on general plastic surfaces.We report a combined method based on in-situ polymerization and lithography,i.e.constructing large-area polyaniline nanofiber arrays on polyethylene terephthalate surfaces.The results reveal that the obtained polyaniline coating prepared via the in-situ polymerization possess large-area and uniform nanofiber array structures.Compared with the drop-casting method,the micro-patterns of polyaniline nanofiber prepared via in-situ polymerization have superior precision and binding capacity with the substrates.Meanwhile,the polyaniline nanofiber sensors via in-situ polymerization show better humidity sensing performance and superior repeatable stability.
