Abstract

The invention relates to the technical field of amphiphilic polymers, in particular to a multi-block copolymer, a multi-block amphiphilic copolymer, a multi-block amphiphilic polymer and a preparationmethod thereof. The multi-block copolymer comprises a polydimethylsiloxane repeating unit and a polyethylene glycol dimethacrylate repeating unit. The invention also provides the preparation method of the multi-block copolymer, the multi-block amphiphilic copolymer prepared from the multi-block copolymer, and the multi-block amphiphilic polymer. The multi-block copolymer and a coating prepared from the polymer provided by the invention have good hydrophobicity and oleophobicity, and also have excellent protein adsorption resistance and diatom adsorption resistance, and the copolymer after entering a quaternary ammonium salt group also has antibacterial ability under the condition of maintaining the properties. The performance defects of the coating are enhanced to a certain extent, and the coating has a wide market application prospect.

Description

technical field [0001] The invention relates to the technical field of amphiphilic polymers, in particular to a multi-block copolymer, a multi-block amphiphilic copolymer, a multi-block amphiphilic polymer and a preparation method thereof. Background technique [0002] Biofouling (biofouling) refers to algae, shellfish and other organisms attaching and growing on the bottom of the ship and the surface of underwater structures in large quantities, reducing or damaging their performance. These fouling marine organisms are called marine fouling organisms. The general term for animals, plants and microorganisms that grow on ships and other artificial underwater structures, mainly including barnacles, oysters, mussels, seaweed and marine bacteria, etc., which can be roughly divided into micro-fouling organisms and macro-fouling Organisms, these marine organisms congregate and grow, forming large areas of fouling. Marine biofouling is a problem that human beings have been facing ...
