Synthesis And Application Of Functionalized Ordered Mesoporous Polymer Materials

Functional polymer materials are the most rapid development of polymer material science, and most cross other fields of science. Its unique physical properties and structural features,which become the focus of the researchers, such as mesoporous polymeric materials. Because of its large specific surface area, tunable pore size and neat superior properties,which is widely used in organic catalysis, environmental protection, biological and medicine, etc.In our paper,we selects low cost, good hydrophobicity, high stability and alkali resistance mesoporous phenolic resins as the support as the carrier. On the one hand, the physical blending method is used to load metal nanoparticles. Using hydrothermal copolymerization with in situ reduction technology, solvent evaporation induced self-assembly techniques; On the other hand, amino functional resorcinarene processing and modification by the in situ copolymerization method etc. while, the neat and orderly mesoporous structure of phenolic resin was synthesized and characterized by a series of technology and preliminary application made a research of the structure-activity relationship on the materials. Our essay is divided into two parts, and the detailed descriptions are listed as follows: 1. Under the condition of alkaline phenol- formaldehyde copolymerization oligomer formation, with ethanol as the solvent evaporation induced self-assembly techniques, using EO-PO polyether type nonionic surfactant F127 structure oriented agent solvent evaporation from combined into two-dimensional hexagonal ordered mesoporous phenolic resin carrier.Phenolic resin is very good toughness, a large number of phenolic hydroxyl, and nanometer metal particles generate strong adsorption keys. By physical blending method, using phenolic resin grinding with copper nitrate, and dispersed better new nanometer copper mesoporous composite materials. In this process, we don’t need to add any reductant, which the metal nanoparticles can be obtained directly, and the operation is simple. After many recyclings, the catalyst can still maintain good performance. 2. Using hydrothermal copolymerization with in situ reduction technology, on the alkaline conditions, nonionic surfactant EO-PO polyether type F127 structure guide agent induced phenol, formaldehyde and nitrophenol oligomer self-assembly, preparaed low cost and high yield of highly ordered type amino-functional 3 d body centered cubic mesoporous polymeric nano sphere. Based on a short hole structure and amino functional groups, which is suitable for adsorption of heavy metal ions. Its adsorption performance under different concentrations, with good prospects of development.
