Antifouling coatings was the mainstream antifouling method with its wide range of applications and cost-effective. Fouling release coating based on silicone elastomer possessed the advantages of environmentally friendly and stable performance，but its application was limited by mechanical property and insufficient static antifouling performance.In this regard，many modification studies have been carried out by scientific and technological workers at home and abroad，including blending/grafting amphiphilic additives，antifouling agents，self-healing technologies，etc.，which effectively improved the comprehensive performance of silicone-based coating. This article reviewed the research status and advantages and disadvantages of several environmentally friendly antifouling coatings，including non-toxic self-renewing antifouling coatings with antithrombotic polymer，biomimetic antifouling coatings，and fouling release coatings based on silicone elastomer，and analyzed the commercialized products，combined with the inspiration of biomimetic antifouling technology，which provided some new perspectives for the environmentally friendly of marineantifouling coatings.
