Flexible and conductive Polypyrrole/Ag/cellulose paper bar with sensitive response to multiple stimulus of pH, mist, breath and finger press

PPy/Ag/cellulose paper bar, prepared by making use of capillary forces of cellulose paper for liquids, presents sensitive response to multiple inducement of pH, gas (mist and human breath), and mechanical behavior (finger press). These feedback stems from the variation of bipolaron density and the m...

Summary:PPy/Ag/cellulose paper bar, prepared by making use of capillary forces of cellulose paper for liquids, presents sensitive response to multiple inducement of pH, gas (mist and human breath), and mechanical behavior (finger press). These feedback stems from the variation of bipolaron density and the modulation of electrons transfer efficiency in PPy/Ag/cellulose paper bar. [Display omitted] •Efficient and rapid way to couple cellulose paper with conductive polymer and Ag.•PPy/Ag/cellulose paper bar with flexibility, portability, low cost, lightweight.•Paper with sensitive reply to multiple stimulus of pH, mist, breath, and finger press. Cellulose paper is a flexible, biocompatible and portable substrate that possess high potential in smart sensing and electronic application field. The performance of cellulose paper can be regulated to meet special requirements by assembling it with functional material. In this work, we show an efficient way to couple cellulose paper with Polypyrrole (PPy) and Ag within 5 s, driven by capillary forces of cellulose paper for liquids. The prepared PPy/Ag/cellulose paper bar exhibited sensitive feedback to multiple inducement of pH, gas (mist and human breath), and mechanical behavior (finger press). These response is attributed to the variation of bipolaron density and the modulation of electrons transfer efficiency in PPy/Ag/cellulose paper bar.
