摘要
两亲性纳米颗粒稳定的Pickering乳液,为两相界面原位生长新纳米晶体提供了足够的空间,构筑了功能性复合材料的合成新方法。我们以GO片层作为稳定剂制备了Pickering乳液,并分别诱导ZIF-8和Cu_3(BTC)_2晶体在其乳液界面成核生长,获得了ZIF-8/GO、Cu_3(BTC)_2/GO复合物,成功应用于CO_2吸附。同样,当我们以Fe_3O_4纳米颗粒稳定的Pickering乳液为模板,通过界面低温原位生长Cu_3(BTC)_2,高温引发甲基丙烯酸甲酯界面聚合,获得了兼具磁性、温敏性与多孔性的PMMA@Fe_3O_4/Cu_3(BTC)_2复合空心微球,可作为载体实现药物控制释放。因此Pickering乳液界面原位合成法具有多种适用性,作为稳定剂的纳米粒子以及原位界面生长获得的纳米粒子都可根据目标要求进行设计,可以获得包括功能化Pickering乳液、纳米复合材料、空心复合材料等结构和形貌的多功能性复合材料,具有广泛应用前景。
In-situ interfacial growth of nanoparticles induced by the Pickering emulsion is a novel and convenient method for preparing hybrids/composites with specific tasks.Stabilized by the GO sheet,the nucleation of ZIF-8,Cu_3(BTC)_2nanoparticles took place at the interface of the GO Pickering emulsion droplets,producing ZIF-8/GO and Cu_3(BTC)_2/GO composites,repetitively,which were successfully applied as CO_2 adsorbents.Meanwhile,through one-pot Pickering emulsion using Fe_3O_4 nanoparticle as the stabilizer,magnetic PMMA@Fe_3O_4/Cu_3(BTC)_2 hollow microspheres were also produced,which showed synergetic multi-functions,including the magnetic separation property by Fe_3O_4,the reverse thermal expansion by PMMA,and the adsorption enhanced permeation by porous Cu_3(BTC)_2.Accordingly,it was used as a good drug carrier for ibuprofen.The type of the nanoparticle stabilizer or the as synthesized nanoparticle can be alternatively changed depending on the specific tasks,therefore,this strategy would have great inspiration for the fabrication of hybrids/composites,such as Pickering emulsions,nanoparticles composites,as well as the hollow composites,and would have promising applications in many areas.
