Photochemical metal-free atom transfer

Student: Christina Wulff Damlund Nielsen

Adhesion of polymer brushes on various substrates is fundamental for many different applications in wide ranging industries. Atom transfer is one of the techniques used to synthesize covalently attached polymer brushes on various surfaces. The process is often based on the use of metals and thus is both expensive and possibly an environmental hazard. However, by removing the metals from the process, the atom transfer can potentially become both cheaper and healthier for the environment.

Metal-free atom transfer has been successfully done using surface-initiated atom transfer radical polymerization (SI-ATRP), the method is today, however, not suitable for most production lines. In this project, optimization of the SI-ATRP method is investigated to secure both the adhesion strength and the speed of the process to prime it for industrial use. Upon success, polymerization of more functionalized monomers can be undertaken.

Data, progress, and status on the project is found here.
