dc.description.abstractA new approach to the synthesis of polymer-based monolithic ion-exchange stationary phases has been developed. This approach involves the formation of a polymeric monolithic template which exhibits the desired structural morphology and which also carries a surface charge. This template is then brought into contact with a suspension of charged nanoparticles containing ion-exchange functional groups and the nanoparticles self-assemble to form a monolayer on the surface of the monolithic scaffold. The characteristics of the monolithic scaffold (pore size, surface area, surface charge) can be optimised completely independently of the characteristics of the nanoparticles (size, type of functional group, charge density, etc). Additionally, the very thin coating of nanoparticles offers rapid mass-transfer during the separation process. This approach is applied to a range of polymer types in different diameter columns and chromatographic performance for the separation of ionic analytes covering a wide range of molecular weights will be reported.
