摘要： Disclosed herein are a polymer composite, a preparation method therefor and an application thereof. The polymer composite comprises the following components in parts by weight: 100 parts polymer powder, 0.1-3 parts nanoparticle A, and 0.05-1.5 parts nanoparticle B. The particle size of nanoparticle A is smaller than that of nanoparticle B, and the mass ratio of nanoparticle A to nanoparticle B is (1-9):1. The small-particle size and large-particle size nanoparticles used in the present application are compounded in a specific ratio, and the two act synergistically as flow agents for the polymer powder, so that the polymer composite has excellent fluidity, permeability and high temperature stability.
