Abstract

Abstract: Stimuli‐responsive polymer materials inspired by biological materials have invoked increasing research interest; however, they still suffer from limitations such as finite amplified responses and poor sensitivity of the unstimulated parts. Herein, a new strategy for creating H + ‐responsive polymer surfaces that are capable of transforming specific local fleeting stimuli into global macroscopic changes is described. The introduction of self‐propagating reactions into the polymer‐surface systems endows them with excellent stimuli‐amplifying properties and response of the unstimulated parts. On the basis of this design, a polymer and enzymatic reaction were employed to enable a specific response to a stimulus and then lead to macroscopic changes of the surface. It is further shown that the prepared H + ‐responsive polymer surfaces can be employed for antibacterial application. This work provides a good example of achieving autonomously reconfigurable materials that respond to local fleeting stimuli. Abstract : Please respond ! pH‐Responsive polymer surfaces that are capable of transforming specific local fleeting stimuli into global macroscopic property changes were designed by the introduction of self‐propagating reactions into polymer‐surface systems (see figure). The H + ‐responsive polymer surfaces can be employed for antibacterial applications, and this design strategy offers methods for achieving autonomously reconfigurable materials.
