Hollow Polyaniline Microsphere Functionalized Paper with Multi-modal Sensitivity to Strain, Humidity and Pressure

文章摘要：

Functionalized paper is a class of promising candidate materials for flexible electronic devices, but preparation of functional paper with multi-modal sensitivity remains a challenge. Herein, functionalized paper with multi-modal sensitivity is developed by introducing hollow polyaniline microspheres (HPM) on the surface of paper. Hierarchical structures of cracks, holes and microgaps on various scales are obtained on the HPM layer, which endows the paper integrated sensitivity to bending strains, relative humidity (RH) and pressure. Interestingly, such paper can be further applied in flexible sensors for monitoring human motions, breathing vapor, sweat of finger, RH of various soils and pressure of finger. Overall, this kind of functionalized paper may not only work as sensing materials for flexible sensor, but also provides a clue to develop other kinds of high-performance electronic materials for supercapacitor, transistors and display devices.
