Metal Ions in Polydopamine Coatings Enhance Polymer-Metal Adhesion.

ABSTRACT: Strong bonding at polymer-metal oxide interfaces is of high importance for lightweight thermoplastic composite structures. However, interfacial adhesion in polymer-metal material systems often poses grand challenges in applications, and hence, tailoring the molecular interactions is necessary. Here, the interfacial adhesion between polycarbonate (PC) and titanium (Ti) is optimized by utilizing metal ion-containing polydopamine (M⁺PDA) produced using two methods, i.e., postdeposition and codeposition with respect to the PDA polymerization. M⁺PDA thin films were formed on the surface of titanium wires, which were then comolded with a PC matrix to form pullout samples in order to evaluate the interfacial energy of adhesion (G _a). For the postdeposition
