Abstract

The invention relates to a preparation method for a fiber coated with a liquid metal. The preparation method for the fiber coated with the liquid metal is based on microfluidic technology and comprises the steps that first, a polymer fiber with a hollow structure is obtained; the polymer fiber is collected by a conveyor belt and a turntable; the liquid metal is poured into a fiber cavity by an injection method; and the fiber coated with the liquid metal is obtained. The fiber coated with the liquid metal is a polymer, and the liquid metal is wrapped inside. The diameter of the fiber is 100-1,000 [mu]m and the length is 1 cm- to 10 m. The preparation method for the fiber coated with the liquid metal has simple operation, low cost, strong experiment reproducibility, uniform fiber structure,controllable size, good conductivity, stretchable deformation, and can be used as indispensable conductive and sensing elements in flexible electronic systems, and has broad application prospects.

Description

technical field [0001] The invention relates to the field of conductive materials, in particular to a fiber wrapped with liquid metal and a preparation method thereof Background technique [0002] Flexible electronics is an emerging electronic technology that combines electronic devices with flexible substrates. Compared with traditional electronic systems, flexible electronic systems have greater flexibility and can perform their functions under different deformation states. However, due to the requirements of flexible electronic systems for materials to deform softly and have good electrical conductivity at the same time, the choice of materials poses challenges. [0003] Liquid metal is a kind of liquid, amorphous and flowable metal at normal temperature. It is a general term for metals or their mixtures whose melting point does not exceed the melting temperature of aluminum. It can be regarded as a mixture composed of positive ion fluid and free electron gas. Liquid me...
