| Summary: | There is great interest in designing functional interfaces. Hyperbranched grafting chemistry is a forgiving method for creating functional interfaces. There are a variety of methods for preparing hyperbranched surface grafts based on condensation reations, free radical reactions, and ring-opening polymerizations. Hyperbranched grafts of poly(acrylic acid) have been prepared on a variety of surfaces including gold, polyethylene, and polypropylene. Such surfaces have been shown to inhibit corrosion, enhance adhesion, immobilize enzymes, and affect biocompatibility. The dissertation show how hyperbranched grafts of poly(acrylic acid) on polyethylene powder can be used to support catalysts. Hyperbranched grafts of poly(acrylic acid) on polyethylene powder can be used to immobilize molecular phosphine-ligated Pd catalysts and Pd crystallites. The catalysts are immobilized in a thin hydrophilic film on a mechanically stable support. Other work in this dissertation shows how hyperbranched poly(acrylic acid) grafts are synthesized on starch supports from hydroxyl grafting sites. Finally the synthesis of hyperbranched poly(l-aminobutadiene) surface grafts is described |
