Embodiment 1
[0064] (1) Prepare 50 mL of solvent with tetrahydrofuran and absolute ethanol at a volume ratio of 9:1, take out 40 mL and put it into Fe 3 o 4 and volume fraction of 4% triethylamine, the remaining 10mL is added polyphosphazene and dihydroxydiphenyl sulfone with a molar mass ratio of 1:3, slowly drop into 3 o 4 solution, and then complete the wrapping at an ultrasonic frequency of 80 kHz, an ultrasonic temperature of 25° C., and an ultrasonic time of 6 hours to obtain magnetic nanoparticles wrapped with polyphosphazene;
[0065] (2) Purify the wrapped magnetic nanoparticles obtained in step (1) twice and then disperse them in chloroform with a dispersion concentration of 4 mg / mL. Take carbon nanotubes with a mass ratio of 1:5 and disperse them in chloroform with a dispersion concentration of 4 mg. / mL, at an ultrasonic frequency of 60kHz, an ultrasonic temperature of 25°C, and an ultrasonic time of 60 minutes, the material carrier was prepared by mixing and loading;
