| Abstract: | Mechanical fatigue and mechanical-chemical effect can harm the stability and durability of flexible electrochemical sensors and electronic devices. To solve the problem, we propose a rigidity/flexibility compatible strategy by implanting Prussian blue into the carbon nanotube array supported by polydimethylsiloxane (PDMS). The PDMS membrane is soft and flexible, and counteracts the external force; meanwhile, Prussian Blue@Carbon Nanotube Hybrid is hard and rigid for the reliable detection of hydrogen peroxide. Consequently, the cyclic voltammetric behavior of Prussian blue keep almost constant during the continuous bending experiments. The results indicate that the rigidity/flexibility compatible strategy is instructive to improve the performance of flexible electrochemical sensors and electronic devices. |
