Liquid metal thermal interface material with elasticity and viscosity and preparation method thereof

The invention provides a liquid metal thermal interface material with elasticity and viscosity, which is prepared by taking a certain amount of polydimethylsiloxane, n-hexane, polyethylene glycol and gallium indium liquid metal alloy as raw materials, and the liquid metal thermal interface material with elasticity and viscosity, which is good in elasticity and viscosity, remarkable in heat conduction effect, free of volatility and capable of being activated and electrically conductive, is prepared. The heat of a heat source can be rapidly transmitted to the radiator for heat dissipation, the working temperature of the heat source is reduced, the heat source can work at a low temperature, and on the premise that the heat conductivity is high, elasticity and viscosity are achieved, any shape can be cut, the contact attachment degree is better, and the contact heat transfer performance is improved. The thermal interface material provided by the invention is a thin-film material, is good in stability, does not de
