Porous poly(ionic liquid)s (PILs) recently have been serving as a multifunctional, interdisciplinary materials platform in quite a few research areas, including separation, catalysis, actuator, sensor, and energy storage, just to name a few. In this context, the capability of photopatterning PIL microstructures in a porous state on a substrate is still missing but is a crucial step for their real industrial usage. Here, we developed a method for in situ rapid patterning of porous PIL microstructures via a maskless photolithography approach coupled with a simple electrostatic complexation treatment. This breakthrough enables design of miniaturized sensors. As exemplified in this work, upon loading Pt nanoparticles into porous PIL microstructures, the hybrid sensor showed outstanding performance, bearing both a high sensitivity and a wide detection range.

通过无掩模光刻技术对多孔聚离子液体进行精确的微图案化,以实现高性能的非酶H 2 O 2传感

多孔聚离子液体(PIL)最近已在相当多的研究领域中用作多功能,跨学科的材料平台,包括分离,催化,致动器,传感器和能量存储等。在这种情况下,仍然缺少在基材上以多孔状态对PIL微结构进行光图案化的能力,但这是其实际工业应用的关键步骤。在这里,我们开发了一种通过以下方法对多孔PIL微结构进行原位快速构图的方法无掩膜光刻方法加上简单的静电络合处理。这一突破使得能够设计出小型传感器。如这项工作中所示,在将Pt纳米颗粒加载到多孔PIL微结构中时,混合传感器表现出出色的性能,既具有高灵敏度又具有宽广的检测范围。
