Examples
Embodiment 1
[0103] use Image 6 device shown.
[0104] Deionized water is selected as the bulk liquid, and it is preheated, that is, the solution substrate is heated to 30°C.
[0105] choose C 60 Chlorobenzene solution (its concentration is 1mg / mL), forms heterogeneous solution, and heterogeneous solution is added dropwise to bulk liquid interface, and solution has spreading tendency on substrate surface and carries out self-disintegration.
[0106] The liquid-liquid system is heated to 40-50°C, and 500 sccm of air is purged inward to change the ambient pressure of the system to obtain micro / nano-structured C 60 .
[0107] to get C 60 Perform atomic force microscopy, such as Figure 7 As shown in (a), crystalline particles having a dumbbell shape were obtained.
[0108] The same process applies to cooling the entire system.
Embodiment 2
[0110] Repeat the process of embodiment 1, difference is: what heterogeneous solution adopts is C 60 carbon tetrachloride solution, and without heat treatment of the liquid-liquid system, the micro / nano-structured C 60 .
[0111] to get C 60 Perform atomic force microscopy, such as Figure 7 As shown in (b), get C 60 Flaky single crystal structure.
Embodiment 3
[0113] Repeat the process of embodiment 1, difference is: what heterogeneous solution adopts is C 60 carbon tetrachloride solution, at a system temperature of 20°C, micro / nano-structured C 60 .
[0114] to get C 60 Perform atomic force microscopy, such as Figure 7 As shown in (c), get C 60 ring structure.
