Example Embodiment
[0024] Implementation example 1:
[0025] First, 10 parts of multi-walled carbon nanotubes and 100 parts of polytetrafluoroethylene are uniformly mixed by a ball mill; put into the reactor, sealed and put into the muffle furnace; heated, maintaining the reaction temperature at 475±25℃, and reacting 1~10 After hours, it was cooled to room temperature, the reactor was opened, and after grinding, the fluorinated carbon nanotubes.
[0026] Multi-walled carbon nanotubes can be directly replaced with the same proportion of single-walled carbon nanotubes.
[0027] Polytetrafluoroethylene can be directly replaced with the same proportion of polyperfluoroethylene propylene or polyvinylidene fluoride solid powder.
[0028] A lower reaction temperature can appropriately extend the reaction time; a higher reaction temperature can appropriately shorten the reaction time. As long as the reaction temperature is controlled at 475±25°C and the reaction time is adjusted accordingly within 1-10 hour...

[0029] Implementation example 2
[0030] First, 10 parts of multi-walled carbon nanotubes and 200 parts of copolymer of tetrafluoroethylene and perfluoroalkyl vinyl ether are uniformly mixed by a ball mill; put into the reactor, sealed and put into the muffle furnace; heated to maintain the reaction temperature After reacting at 550±50°C for 1-10 hours, cool to room temperature, open the reactor, and mill the fluorocarbon nanotubes.
[0031] Multi-walled carbon nanotubes can be directly replaced with the same proportion of single-walled carbon nanotubes.
[0032] The copolymer of tetrafluoroethylene and perfluoroalkyl vinyl ether can be directly substituted with the same proportion of ethylene and tetrafluoroethylene copolymer.
[0033] A lower reaction temperature can appropriately extend the reaction time; a higher reaction temperature can appropriately shorten the reaction time. As long as the reaction temperature is controlled at 550±50°C and the reaction time is adjusted acco...

[0034] Implementation example 3
[0035] First, 10 parts of multi-walled carbon nanotubes and 300 parts of dodecafluoroheptanol are mixed uniformly by a colloid mill; put into the reactor, sealed and put into the muffle furnace; heated, maintaining the reaction temperature at 150±500C, and reacting 1~ After 10 hours, it was cooled to room temperature, the reactor was opened, and after grinding, the fluorocarbon nanotubes were obtained.
[0036] Multi-walled carbon nanotubes can be directly replaced with the same proportion of single-walled carbon nanotubes.
[0037] Dodecafluoroheptanol can be directly substituted with the same amount of liquid organic fluoride with higher fluorine content such as derivatives of dodecafluoroheptanol.
[0038] A lower reaction temperature can appropriately extend the reaction time; a higher reaction temperature can appropriately shorten the reaction time. As long as the reaction temperature is controlled at 150±50°C and the reaction time is adjuste...
