%X Herein, we report a simple coat/cure preparation of epoxide-functionalized surfaces using a photocurable copolymer technology. The photocurable copolymer, poly(glycidyl methacrylate-co-butyl acrylate-co-4-benzoylphenyl methacrylate) (GBB), was synthesized by single electron transfer¨Cliving radical polymerization (SET-LRP). The epoxide content in the copolymer was tuned by controlling the content of glycidyl methacrylate. Three copolymers, GBB(1), GBB(2), and GBB(3), with epoxide contents of 22, 63, and 91 mol %, respectively, were cast onto polypropylene films and photocured by UV-light exposure. Subsequently, iminodiacetic acids (IDA) were immobilized onto the GBB-coated materials via a ring-opening reaction. The IDA-functionalized coatings GBB(1)-IDA, GBB(2)-IDA, and GBB(3)-IDA presented IDA contents of 1.47 ¡À 0.08, 18.67 ¡À 1.46, and 49.05 ¡À 2.88 nmol/cm2, respectively, which increased as the epoxide content increased. The IDA-functionalized GBB coatings exhibited metal chelating capability toward transition metal ions (e.g., iron and copper). The reported photocurable copolymer technology offers a facile and tunable preparation of epoxide-functionalized surfaces, with potential extended applications in biopatterning, active packaging, and nanotechnology
