Problems solved by technology

Template molecules are difficult to elute. During the pre-assembly or recognition process of template molecules, the binding and dissociation speeds of template molecules are generally slow, which is not suitable for rapid recognition.
Moreover, the recognition mechanism is far from that of biometrics, so this method develops slowly

Abstract

The invention relates to a method for preparing a bisphenol A molecularly imprinted material from a functional monomer containing a template molecular structure. The method comprises mixing a functional monomer and a functional monomer containing a template molecular structure in an acetonitrile solution, uniformly stirring the mixed solution, feeding nitrogen into the mixed solution to remove oxygen, adding a template molecule into the solution, adding an initiator into the solution, carrying out uniform mixing, putting the mixture in an environment at a temperature of 60-70 DEG C for polymerization for 6-20h, and then carrying out elution. The bisphenol A molecularly imprinted material has good affinity to the template molecule, has a fast mass transfer rate and has good molecular selectivity and specificity.

Description

technical field [0001] The invention relates to the preparation of separation materials, in particular to a method for preparing bisphenol A molecular imprinted materials from functional monomers containing template molecular structures. Background technique [0002] Molecular imprinting (molecular imprinting) is an artificial biomimetic material synthesis technology developed based on molecular assembly in recent years that is selective for specific molecules (template molecules or imprinted molecules). This technology is also vividly described as a technology for creating artificial "locks" that identify "molecular keys". Taking non-covalent molecular imprinting as an example, the target molecule to be recognized is used as a template, and the template molecule and the polymerizable functional monomer are carried out through weak non-covalent interactions (such as hydrogen bonds, electrostatic interactions, hydrophobic interactions, etc.). Assembled and polymerized with t...
