Abstract
Embodiments of the present disclosure provide a coating-free non-stick pan and a preparation method thereof. An inner surface of the non-stick pan is provided with a uniformly distributed micro-nano concave-convex structure. The micro-nano concave-convex structure includes micron-sized concavities and convexities. The micron-sized concavities and convexities include micron-sized protrusions or micron-sized depressions. The micron-sized protrusions are formed by particulate films formed by particles, the particulate films have a thickness of 0.1-0.98 μm, and the particles have a particle size of 0.02-0.3 μm. The micron-sized depressions have a diameter of 0.1-0.98 μm.
