Embodiment 1
[0025] Weigh a certain amount of multi-walled carbon nanotubes and dimethyl isophthalate into a 1-500ml reactor. Connect the reaction device, check the air tightness, use CO 2 Remove the air in the reactor, and then adjust the temperature to a temperature of 0-600°C or higher. Will CO 2 Pass into the reactor, pressurize to 0-30MPa or even higher, and mix for 0-300min or even longer. The mixed supercritical system is quickly sprayed into the container through a fine nozzle for collection, and after cooling, the sample is taken out.
[0026] The dispersion of the two types of multi-walled carbon nanotubes was observed through scanning electron micrographs. figure 1 , figure 2 These are scanning electron micrographs of multi-walled carbon nanotubes that do not contain dimethyl isophthalate during RESS treatment and multi-walled carbon nanotubes that do not contain dimethyl isophthalate during RESS treatment. By comparison, we found that dimethyl isophthalate has wrapped the multi-...
Embodiment 2
[0028] Weigh a certain amount of single-walled carbon nanotubes and dimethyl isophthalate into a 1-500ml reactor. Connect the reaction device, check the air tightness, use CO 2 Remove the air in the reactor, and then adjust the temperature to a temperature of 0-600°C or higher. Will CO 2 Pass into the reactor, pressurize to 0-30MPa or even higher, and mix for 0-300min or even longer. The mixed supercritical system is quickly sprayed into the container through a fine nozzle for collection, and after cooling, the sample is taken out.
[0029] The dispersion of the two types of single-walled carbon nanotubes was observed through scanning electron micrographs. figure 1 , figure 2 These are scanning electron micrographs of single-walled carbon nanotubes that do not contain dimethyl isophthalate during RESS treatment and single-walled carbon nanotubes that do not contain dimethyl isophthalate during RESS treatment. By comparison, we found that dimethyl isophthalate has wrapped the si...
