Embodiment 1
[0024] (1) Mix 15mmol anhydrous ferric chloride, 5mmol sodium hydroxide, 50mL ethylene glycol and 3.6ml deionized water and transfer to a three-necked flask, mix well, heat up to boiling, then keep boiling and reflux for 8h, stop react, cool to room temperature, separate and wash to obtain ferric oxide nanoparticles. figure 1 Shown is the transmission electron microscope (TEM) photo of the obtained iron ferric oxide nanoparticles. It can be seen from the figure that the average size of the obtained nanoparticles is between 20-40nm, with uniform particle diameter, moderate size, good dispersion and no agglomeration.
[0025] (2) Disperse 0.5 g of the ferric oxide nanoparticles obtained above in 100 ml of water, add 3 ml of APTES, and heat to 65 ° C under mechanical stirring; after 12 hours of reaction, stop stirring, cool to room temperature, separate and wash APTES modified ferric oxide nanoparticles were obtained. figure 2 Shown is a transmission electron microscope (TEM) p...
