Abstract

The invention provides an MXene/polyaniline nano-composite anticorrosive and antibacterial coating and a preparation method thereof, and the MXene/polyaniline nano-composite anticorrosive and antibacterial coating comprises the following components in parts by weight: 40-70 parts of epoxy resin, 1-5 parts of an MXene/polyaniline composite material, 1-2 parts of a defoaming agent, 1-2 parts of a leveling agent and 10-30 parts of a curing agent. The MXene and polyaniline in the prepared coating have a synergistic effect, so that the nano composite coating not only has conductivity, but also has antibacterial property, and also provides chemical corrosion prevention and physical barrier effects. The preparation method of the nano-composite coating is simple, the anti-corrosion and antibacterial properties are good, and large-scale industrial production is easy.

Description

technical field [0001] The invention relates to the technical field of functional coatings and composite materials, in particular to an MXene / polyaniline nanocomposite anti-corrosion and antibacterial coating and a preparation method thereof. Background technique [0002] With the rapid development of social economy, various coatings are widely used in construction industry, machinery manufacturing, shipbuilding and other fields. However, in daily use, the occurrence of electrochemical corrosion and chemical corrosion may cause very serious consequences. At present, the traditional functional coatings can no longer fully meet the requirements of the industry. Coating a layer of anti-corrosion coating on the surface of the material to isolate the external environment from contact with the metal surface is one of the most convenient and effective anti-corrosion methods at present. Polyaniline is a conductive polymer that was first used in the field of anti-corrosion. It can ...
