This letter reports the synthesis and characterization of functionalized magnetic nanoparticles associated with chemical gels and their application to the conservation of cultural heritage. Magnetic nanoparticles, which are associated with acrylamide ethylene oxide polymers, produce a sponge that can be loaded with oil-in-water microemulsions, forming a magnetically responsive gel-like system and acting as a permanent hydrogel. The magnetic gel-like system can be used for specific applications in detergents or in the release of the loaded material. The system can be magnetically manipulated and cleaned from the loaded materials and then dried and reused for a different application. We report an important application of this new nanomagnetic responsive material in the field of cultural heritage conservation.
这封信报道了与化学凝胶相关的功能化磁性纳米粒子的合成与表征及其在文化遗产保护中的应用。与丙烯酰胺环氧乙烷聚合物相关的磁性纳米粒子产生一种海绵，该海绵可负载水包油微乳液，形成磁响应凝胶状体系并充当永久性水凝胶。该磁凝胶状体系可用于洗涤剂中的特定应用或负载材料的释放。该体系可通过磁力进行操控，并从负载材料中清除，然后干燥并重新用于不同的应用。我们报道了这种新型纳米磁响应材料在文化遗产保护领域的一项重要应用。
