Abstract:

A series of hyperbranched materials have been developed that allow for the transportation of desired functional groups to the surface of a polymer blend by simple solution casting techniques. These materials have been employed to transport polyoxometalates, or POMs, to the surface of a polyurethane- polyether copolymer film. providing for a 10x increase in POM concentration at the surface compared to the bulk. The films were evaluated using x-ray photoelectron spectroscopy XPS and contact angle analysis, and their surface chemistry was dominated by the hyperbranched polymer incorporated into the blend.
