【摘要】 本文提出了一种绿色而简单的制备多孔复合物的方法。以HKUST1为Pickering乳化剂,PVA为共乳化剂,形成水包二氧化碳高内相乳液模板制备出相互贯通的多孔复合物整体材料。合成的复合物MOF/PAM进行了SEM,XRD,FT-IR,TGA,N2吸脱附测试等表征。从SEM图中可看出复合物相互贯通的多级孔结构,其"胞体"与贯通孔直径分别在10-80μm和0.5-25μm之间。N2吸脱附结果说明HKUST-1的微孔及复合物MOF/PAM的大孔结构。
【Abstract】 Herein,a green and facile method for the generation of composite monolith was presented.HKUST-1(Pickering emulsifier)and PVA(co-emulsifier),were used to stabilize supercritical carbon dioxide in water as high internal phase emulsion(HIPE)template to prepare interconnected hydrophilic porous monoliths.The as-synthesized MOF/PAM composites were characterized by FT-IR,SEM,XRD,TGA and N2 adsorption-desorption test.The SEM patterns show that composites are interconnected,the void sizes are 10-80μm and the interconnected pore throats are 0.5-25μm approximately.The curves of N2 adsorption-desorption indicated the micropore and macropore structure of HKUST-1 and MOF/PAM.
