The Thiophene Molecularly Imprinted Polymer And The Imprinted Blend Membrane Were Prepared By Radiation Polymerization

As a new functional polymer material,molecularly imprinted polymers(MIPs)have been widely used in many fields for its specific recognition and high selectivity.In this paper,the hollow double templates polymers(H-MIPs)were prepared via radiation polymerizationmethods.Based on the principle of surface molecular imprinting technique,without the addition of the initiator,using SiO2 as the solid support matrix,which was vinyl modified by 3-(methacryloyloxy)propyltrimethoxysilane(MPS),methacrylic acid(MAA)as the functional monomer,benzothiophene(BT)and benzothiophene(DBT)as double templates.Finally with the hydrofluoric acid,the SiO2 was removed.The effect of irradiation dose on the morphology of polymer microspheres was investigated.This functionalized material was characterized by FT-IR?SEM?TEM and TGA,which demonstrated a high adsorption performance and selectivity.The results showed that H-MIPs showed higher adsorption performance and better performance than MIPs,and the adsorption capacity of BT and DBT were 195 ?mol/g and 203 ?mol/g,respectively.It provided a good method for the desulfurization of fuel oils in the petroleum industry.In this paper,based on the characteristics of membrane materials of low cost,low energy consumption,high efficiency,good recognition and simple preparation process,imprinting polymer membranes was obtained by solution phase inversion method,which regarding PSF as film material,DMF as casting solution,MIPs as filler.In the course of the experiment,the effect of film-forming material,coagulation bath temperature and membrane concentration for the membrane structures was studied,the membrane performance evaluation device and scanning electron microscopy were used to study the film-forming properties and selective adsorption ability.The results showed when the content of PSF was 25%,the coagulation bath temperature was 35?,the film was the best.And the process of sothermal adsorption showed that this film had a high adsorption amount on the target,so that the structure could be separated from the similar structure substances.
