Controlled attachment of PAMAM dendrimers to solid surfaces

Amine-terminated polyamidoamine (PAMAM) dendrimers can be immobilized onto anhydride-functionalized pulsed plasma polymer surfaces via amide linkage formation. The packing density of dendrimers at the surface can be tailored by programming the pulse duty cycle parameters during plasma polymerization. These PAMAM dendrimer layers are shown to be useful for a variety of surface-related phenomena, for example, fluorination, adhesion, and gas barrier enhancement.
