The present invention combines organic cross-linking and inorganic cross-linking for surface modification, so that the resin has a gradual hierarchical structure, thereby ensuring that it has excellent blood absorption properties, while also having excellent water absorption properties and gel strength, and other performance.

The disclosure discloses a nicotinamide dummy template surface molecularly imprinted polymer, a preparation method and application thereof, and belongs to the technical field of chemical materials. The preparation method of the disclosure includes the steps of preparing a modified silica gel carrier, preparing a dummy template surface molecularly imprinted polymer and the like. The disclosure uses nicotinamide, a structural analogue of imidacloprid and acetamiprid, as a dummy template to prepare a silica gel surface molecularly imprinted polymer. The polymer not only can effectively avoid pollution caused by the leakage of template molecules, but also can specifically remove imidacloprid and acetamiprid from water-soluble tea extracts. The removal rate of imidacloprid and acetamiprid is greater than 96% and 93%, respectively, and the loss of tea polyphenols in the extracts is less than 10%. In addition, the molecularly imprinted adsorption column prepared by the disclosure can be eluted with ethanol solution, and the eluted adsorption column can be recycled, so the disclosure can be well applied to the preparation technology of tea extracts and has good application prospects.

Novel carbon molecular sieve (CMS) compositions comprising carbonized vinylidene chloride copolymer having micropores with an average micropore size ranging from 3.0 to 5.0. These materials offer capability in separations of gas mixtures including, for example, propane/propylene; nitrogen/methane; and ethane/ethylene. Such may be prepared by a process wherein vinylidene chloride copolymer beads, melt extruded film or fiber are pretreated to form a precursor that is finally carbonized at high temperature. Preselection or knowledge of precursor crystallinity and attained maximum pyrolysis temperature enables preselection or knowledge of a average micropore size, according to the equation ?=6.09+(0.0275C)(0.00233T), wherein ? is the average micropore size in Angstroms, C is the crystallinity percentage and T is the attained maximum pyrolysis temperature in degrees Celsius, provided that crystallinity percentage ranges from 25 to 75 and temperature in degrees Celsius ranges from 800 to 1700. The beads, fibers or film may be ground, post-pyrolysis, and combined with a non-coating binder to form extruded pellets, or alternatively the fibers may be woven, either before or after pre-treatment, to form a woven fiber sheet which is thereafter pyrolyzed to form a woven fiber adsorbent.
