Monolithic porous copolymers with 3D structure were prepared via CO₂‐in‐water high internal phase emulsions template by graft copolymerization of sodium methacrylate (MAANa) on to methyl cellulose (MC) backbone. The yielded copolymer monoliths are characterized by Fourier transform infrared spectra, scanning electron microscopy (SEM), and mechanical instrument, the swelling degree of MC‐g‐PMAANa monoliths with different crosslinker in diverse pH were investigated. The adsorption performance of monolith to Cu(II) were conducted to explore its adsorption capacity to heavy metal ions from the wastewater. Then, a strategy of in situ growth of metal‐organic frameworks (MOFs) on MC‐g‐PMAANa that adsorbed with metal ions was proposed first. The X‐ray powder diffraction, SEM, and Brunauer‐Emmett‐Teller (BET) surface area result of MC‐g‐PMAANa/MOFs composites indicated that the MOFs nanoparticles were grown uniformly on the monolith wall without destroying its original 3D porous structure. Compared with MOFs nanoparticle, MC‐g‐PMAANa/MOFs composites have advantages of easy operation and handle, which more conform to practical application. Furthermore, the antibacterial activity of MC‐g‐PMAANa/MOFs was evaluated by disk agar diffusion and optical density methods. In addition, MC‐g‐PMAANa/Cu‐BTC composite was applied to dye adsorption, which has proved the underlying application of such composites in dye removal.

通过水中二氧化碳HIPE模板制备多孔整料并在其上原位生长金属有机骨架以用于多种应用

通过将甲基丙烯酸钠（MAANa）接枝共聚到甲基纤维素（MC）骨架上，通过CO ₂水中高内相乳液模板制备具有3D结构的整体多孔共聚物。用傅立叶变换红外光谱，扫描电子显微镜（SEM）和机械仪器对所得的共聚物整体材料进行表征，研究了具有不同交联剂的MC- g- PMAANa整体材料在不同pH下的溶胀度。进行了整料对Cu（II）的吸附性能，以探讨其对废水中重金属离子的吸附能力。然后，提出了一种在MC‐ g上原位生长金属有机框架（MOF）的策略‐首先提出了吸附有金属离子的PMAANa。MC- g- PMAANa / MOFs复合材料的X射线粉末衍射，SEM和Brunauer-Emmett-Teller（BET）表面积结果表明，MOFs纳米颗粒在整体壁上均匀生长，而不会破坏其原始3D多孔结构。与MOFs纳米颗粒相比，MC- g- PMAANa / MOFs复合材料具有易于操作和处理的优点，更符合实际应用。此外，通过盘琼脂扩散法和光密度法评估了MC- g- PMAANa / MOF的抗菌活性。另外，MC - g -PMAANa / Cu-BTC复合材料被用于染料吸附，这证明了这种复合材料在染料去除中的潜在应用。
