Stimuli-Responsive Mussel-Inspired Polydopamine Material
The first material-independent surface chemistry called polydopamine coating was introduced in Chap. 14. Surface properties for a given material can be controlled by the coating. Therefore, one can provide stimuli-responsiveness on a surface level by co-immobilization of chemical moieties that are sensitive to light, pH, temperature, or humidity when performing polydopamine coating. Alternatively, covalent conjugations of stimuli-responsive functional groups to dopamine hydrochloride result in preparations of series of dopamine derivatives. One-step coating of these derivatives becomes general methods to incorporating stimuli-responsive properties on virtually any material surfaces. This chapter provides detail information on this topic.
