Surface modification using functional polymers has attracted much attention owing to its potential applications in various fields including biomedical and energy conversion technologies. In these applications, efficient grafting of polymers onto solid surfaces is required because the delamination of the surface-bound polymers eventually leads to a significant decrease in its function. Herein, a metal-mediated strategy to graft polymers onto solid surfaces is reported. An efficient polymer grafting onto polydopamine- and tannic acid-functionalized surfaces is achieved via Fe(III)- or Zr(IV)-mediated cross-linking reactions. This strategy yields polymer multilayers that suppress platelet, fibroblast, and bacterial adhesion onto the solid surfaces. Furthermore, the polymer grafting can be selectively achieved on specific sites of solid surfaces. |
