Characterization and Control of Matrix for Surface Molecular-imprinted Polymer

In creating highly selective imprinted polymers is important to make the polymer matrix rigid and attach the functional host molecule firmly onto the polymer surface. In the present study, the molecular weight distribution of surface molecular imprinted polymers prepared without a crosslinking agent was measured, and the essential factors affecting the characteristics of the polymer matrix were examined. The optimum polymerization conditions based on the results were applied, and we succeeded in enhancing the imprint effect and the selectivity of Zn (II)-imprinted polymers. Key words: surface molecular imprinting, polymer matrix, metal ion recognition, polystyrene, molecular weight distribution.
