Description

Technical Field

[0001] The present invention relates to the technical field of polymers, and in particular to a method for preparing a multiphase material. Background Art

[0002] Multiphase materials refer to materials with different properties that are "compounded" together to form a material. Due to their different properties, the material has phase interfaces, mainly solid-solid, solid-liquid, liquid-liquid, gas-solid, and gas-liquid phase interfaces. The various materials complement each other in terms of performance, producing a synergistic effect, which optimizes the comprehensive performance of the material to meet various different usage requirements. Multiphase composite materials are composed of a continuous phase matrix and a phase reinforcement enclosed by the matrix. Compared with traditional single-material structures, multiphase material structures can give full play to the performance advantages of each material, such as corrosion resistance, wear resistance, and light weight, and are widely used in various fields.

[0003] However, existing multiphase materials are prepared through indirect methods. These methods rely on forming a secondary interface within a base material through multiple solid-phase, solution, or evaporation synthesis processes, resulting in a large specific surface area, enhanced thermal stability, and a typical multiphase structure with a high degree of density distribution. However, this method requires complex control of conditions, high base material costs, and high requirements for material preparation technology. Furthermore, the complex preparation process precludes mass production.

[0004] Therefore, there is an urgent need to provide a method for preparing multiphase materials to address the shortcomings of the existing technology. Summary of the Invention
