Publication number: CN102850490

Abstract: The invention provides a method for preparing a molecularly imprinted material by a POSS compound as a cross-linking agent. The method comprises the following steps of dissolving a template molecule and a functional monomer in a pore-foaming agent, then standing for 12 to 24 hours so that the template molecule and the functional monomer interact fully, adding a cross-linking agent and an initiator into the pre-polymerized solution obtained by the previous step, carrying out ultrasonic treatment for 5 to 15min for full dissolution, removing oxygen in the mixture by nitrogen flows for 5 to 15min, sealing, putting the sealed mixture into an oven having a temperature of 60 to 80 DEG C, and carrying out a reaction process in the oven for 8 to 24 hours. The method has simple processes. The molecularly imprinted material obtained by the method has good high-temperature resistance, high selectivity and good physical and chemical properties, can be used for selective enrichment and separation of different types of objects in selection of different template molecules, and has a wide application range.
