[求助] 纳米四氧化三铁很容易被氧化吗?

各位做过的和正在做纳米四氧化三铁的虫子们,求教一下,纳米四氧化三铁,很容易被氧化吗?很容易吸潮吗?还有就是coated其他的有机分子后,能在红外干燥箱内干燥吗?不会变质吧?

恭候各位的解答

In general, Fe3O4 is highly susceptible
to oxidation when exposed to the atmosphere. In most cases, the
synthesized Fe3O4 NPs display in homogeneity, poor stoichiometry,
higher crystallite size, aggregate, and bad stability. Furthermore,magnetic NPs of iron oxides tend to aggregate together and thus
lose the specific properties associated with their nanostructures
due to anisotropic dipolar attraction. In practical applications,
Fe3O4 NPs should not only be synthesized but also exhibit unique
properties such as chemical stability, water solubility, and biocompatibility,
as well as uniform in size and well dispersed in
dispersant. To realize these critical requirement, design and synthesis
of uniform and functionalized Fe3O4 composite particles have
attracted more and more attention in recent years due to their
fundamental scientific interest and wide applications [17–22].
