The invention relates to and discloses a method for preparing a multiphase fiber based on a microfluidic-electrostatic spinning technology. A microfluidic chip is placed under a high-speed microscope, an external phase solution and an internal phase solution respectively enter the microfluidic chip at different flow speeds through an injection pump, and a multi-phase spinning solution is formed after the microfluidic chip regulates and controls the external phase solution and the internal phase solution; different flowing states are formed in a micro-channel structure by regulating and controlling the flowing speed of each phase solution; the multi-phase spinning solution regulated and controlled by the microfluidic chip is enabled to have static electricity by utilizing a high-voltage power supply, and charged jet flow is formed at an outlet of the microfluidic chip; and along with the movement of the jet flow in the electric field, the solvent in the multi-phase spinning solution is gradually volatilized, a
