Biofouling on marine vessels and bacterial growth on biomedical surfaces bring huge economic loss to our society. Traditional antifouling and antibacterial surfaces contain toxic substances or antibiotics, which can threaten the environments and raise the risk of inducing drug-resistance strains. In the long-term evolution process of natural organisms, they present multiple functions through the joint action of their own morphology, structure, and other factors to achieve the maximum adaptation to the environment. Many of natural organisms have developed antifouling and antibacterial strategies. Inspired by these strategies, lots of artificial surfaces have been fabricated and tested. They are highly efficient and environmental-compatibility, and they have potential to achieve enhanced antifouling capabilities and desirable properties by combining the characteristics of novel materials. This book focuses on the research and application of bioinspired antifouling surfaces in the two major fields—marine industry and biomedical field. It is intended for mechanical manufacturing and biomedical researchers, enthusiasts and students.

Biofouling is the gradual accumulation of fouling organisms (such as bacteria, diatoms, and barnacles) on wetted surfaces. Back in 1943, Zobell first discussed biofilm formation and related corrosion on solid surfaces. Since then, the negative impacts, the formation mechanism, and the solutions of biofouling have been studied by many researchers, and it became the focus of extensive research in recent years. The growth of fouling organisms on marine vessels increases drag and accelerates corrosion, which can lead to high fuel consumption and excessive maintenance costs. Marine biofouling consumes billions of dollars and causes environmental disasters every year in the global shipping industry. Excessive fuel consumption increases the emissions of greenhouse gas (e.g., CO2), harmful compounds (e.g., NOxand SOx), and atmospheric pollutants. CO2can contribute to the global warming trend and NOxand SOxcause acid rain and soil damage. The atmospheric pollutants in the air increase the health risk of human beings. These harmful emissions cause approxi mately 60 000 deaths globally and€200 billion in losses every year. Historically, conventional antifouling coatings were incorporated with toxic substances, which have been banned in many countries because of their toxicity to the marine envi ronment. Hence, the development of effective, environmentally friendly, and lowcost antifouling coatings is necessitated. The formation of biofilm on biomedical surfaces and public facilities also leads to biofouling, which can bring bacterial infection risk to patients and public health. The application of antibiotics can reduce the suffering of human beings caused by bacterial infections. However, the optimism of antibiotic application was weakened by the discovery of drugresistant strains. Therefore, it is necessary to construct an effective and antibioticsfree antibiofouling and antibacterial surface coating in medical settings to prevent bacterial adhesion and settlement, reducing the spread of infections.
In the longterm evolution process of natural organisms, they present multiple functions through the joint action of their own morphology, structure, and other factors to achieve maximum adaptation to the environment. Many natural organ isms have developed antifouling strategies. Inspired by these strategies, lots of artificial surfaces have been fabricated and tested. They are highly efficient and environmentalcompatibility and they have the potential to achieve enhanced antifouling capabilities and desirable properties by combining the characteristics of novel materials. This book will focus on the application of bioinspired antifouling surfaces in two major fields—the marine industry (chapters2–5) and the biomedical field (chapters6–10). We expect this book not only to satisfy scientific curiosity but also contribute to the design and application of bioinspired antifouling surfaces.
