Abstract

The invention discloses a preparation method of a metal / cross-linked polyphosphazene coaxial nano cable, which comprises the following steps: a metal nano wire, hexachlorocyclotriphosphazene and 4, 4'-dihydroxy diphenyl sulfone are dispersed into organic solvent under ultrasonic condition; and then acid-binding agent triethylamine is added to have ultrasonic reaction for 6h to 10h at 20 DEG C to 40 DEG C; after reaction, the metal / cross-linked polyphosphazene coaxial nano cable without the 20nanometer to 300nanometer thick shell layer material is obtained after centrifugal separation, washing and vacuum drying. The process is simple and has wide scope of application; in addition, the shell layer material is a highly cross-linked polyphosphazene material which is characterized by controllable thickness, strong sealing performance, thermal stability, electric insulation and good flexibility. The metal / cross-linked polyphosphazene coaxial nano cable is expected to be widely applied in the field of electronic nano devices.
