The utility model discloses a polymer film and a triboelectric pressure sensor, the polymer film comprises a first surface, the first surface is provided with a plurality of first protruding structures, the top of the first protruding structures is provided with first nanometer fiber network structures in a dispersed manner, and the first nanometer fiber network structures are provided with second nanometer fiber network structures in a dispersed manner. The plane where the first nanofiber network structure is located is perpendicular to or inclined to the protruding direction of the first protruding structure. According to the utility model, the surface of the polymer film is provided with a multi-layer micro-nano composite structure, so that a new working mechanism of combining vertical contact separation and transverse sliding friction of the triboelectric pressure sensor is realized, the electric signal output of the triboelectric pressure sensor can be greatly improved, and the sensitivity is improved. 本
