The invention discloses a method of preparing a high molecule-based common nepenthes-simulating super-lubricating surface by means of a flame spraying technology. The method comprises the following steps: constructing a high molecular coating on the surface of a matrix by means of the flame spraying technology; and then covering the matrix with low surface energy lubricating oil to obtain the highmolecule-based common nepenthes-simulating super-lubricating surface. The invention discloses a preparation method of the high molecule-based common nepenthes-simulating super-lubricating surface, wherein the follow-up modification process is simplified, and is simpler, good in repeatability and suitable for large-area preparation and industrial application. The high molecule-based common nepenthes-simulating super-lubricating surface prepared can prevent water drops on the surface of a material.
