An ultra-thin flexible vapor chamber and a preparation method and application thereof are provided. Based on projection micro stereolithography technology, the preparation method of the present disclosure enables preparation of the ultra-thin flexible vapor chamber of a micro-scale and high-precision ultra-thin dot matrix array structure with excellent liquid absorption and support capabilities. To improve properties of the vapor chamber, various dot matrix array structures including but not limited to a star-shaped array structure, a radial array structure and a parallel array structure, can be designed by topologically optimizing a distribution of the dot matrix array structure according to a location of a heat source. The ultra-thin flexible vapor chamber prepared herein not only meets requirements of an electronic device for a vapor chamber thickness and weight, but also features flexibility and bendability, stronger thermal conductivity, less thermal resistance and less energy consumption.
