各位做過的和正在做納米四氧化三鐵的蟲子們,求教一下,納米四氧化三鐵,很容易被氧化嗎?很容易吸潮嗎?還有就是coated其他的有機分子后,能在紅外干燥箱內(nèi)干燥嗎?不會變質(zhì)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]. |
