NOVELTY - Modified fluorine coating comprises fluorine coating and fluorocarbon material dispersed in the fluorine coating, the fluorocarbon material includes fluorinated graphite and/or fluorinated graphene, and the mass fraction of fluorine atoms in the fluorinated carbon material is 30-61 wt.%. USE - The modified fluorine coating is useful in composite coating and cooker. ADVANTAGE - The modified fluorine coating: enables cooker can be made non-stick for a long time and has a long non-stick life; and solves problem that the coating formed by the coating in the prior art has a persistent nonstick bad, and causes the problem of short nonstick life. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) modified base oil, comprising base oil and fluorocarbon material dispersed in the base oil, and the base oil is a base oil of fluorine coating; (2) modified medium oil, comprising medium oil and fluorocarbon material dispersed in the medium oil, and the medium oil is the medium oil of the fluorine paint; (3) composite coating, comprising base oil layer and top oil layer formed on the surface of the bottom oil layer, the bottom oil layer is formed from a modified base oil, and the top oil layer is formed from a top oil; and (4) cooker, comprising cooker body and composite coating formed on the surface of the cooker body.
