Title:
POROUS CROSSLINKED MATERIAL, PREPARATION METHOD FOR SAME, AND APPLICATIONS THEREOF
Document Type and Number:
WIPO Patent Application WO/2022/160356
Kind Code:
A1
Abstract:
A porous crosslinked material, a preparation method for same, and applications thereof. A TPC-OTBS n-hexane solution is added to a mixture of TPC-OSO2F, DMF, and DBU and allowed to stand to produce a crosslinked solvent gel; the crosslinked solvent gel is added to methanol, stirred, and dried to produce the porous crosslinked material. The gel acquired can be prepared into a pore-rich solid porous organic polymer material by means of solvent exchange. SEM and TEM are used to characterize the surface and internal morphologies of the solid material, and the porous morphology thereof is discovered, with large pores being the majority. Infrared and nuclear magnetic resonance are used to characterize the structure of a crosslinked polysulfate; the complete reaction of a sulfuryl fluoride group is proven by means of solid-state fluorine nuclear magnetic resonance spectroscopy and XPS element analysis; and the porous structure of the crosslinked polysulfate allows same to be provided with improved application prospect in terms of adsorption. The adsorption capacity with respect to iodine in an organic phase is up to 702 mg/g, the adsorption of bisphenol A in an aqueous phase also provides an improved result, and the maximum adsorption capacity is as high as 205 mg/g.
