The preparation of three different shapes a-Fe2O3 nano-particles by means of force hydrolyzation was discussed in this paper. By controlling the experimental conditions (Fe3+ concentration, acidity, reaction time, reaction temperature etc.), the particles with different shapes (ellipsoidal, pseudocubic, sphere) were obtained.
本论文采用强迫水解法制备了三种不同形貌的α-Fe_2O_3水溶胶,通过对反应条件Fe~(3+浓度、酸度、反应温度、反应时间等的控制获得了不同形貌(椭球形、球形、准立方体形)和粒径的α-Fe_2O_3,并利用浸渍—提拉法制备了α-Fe_2O_3纳米粒子薄膜。

The results showed that spherical BaCO3 particles with low reaggregation and uniform size of about 100nm could be prepared by using solid-state reaction of Ba(NO3)2 and Na2CO3 at room temperature; while stick shape particles, whose size is not uniform, were obtained for the BaCl2 2H2O and Na2CO3 system. For the Ba(NO3)2 and NH4HCO3 system, the products are spherical whose average size is about 200nm.

A novel polymer of Poly(diglycidyl maleate-co-stearyl methacrylate) was synthesized and its structure was characterized by ~1H NMR. Its self-assembly behavior was studied in different solvents. It was found that vesicles and tubule-liked aggregates can be obtained through self-assembly of P(DGMA-co-SMA)/THF/EtOH system. And spheral aggregates were obtained in P(DGMA-co-SMA)/THF/H_2O system while the spheral aggregates were converted into rod-liked aggregates and line-liked aggregates after aged for different time.
