The aim of BlueMat is to develop nature-inspired, sustainable and interactive material systems that reveal their functionality in water or aqueous environments, or that derive their unique functionality from the special properties of water. Many biological materials derive their functionality from hybrid multiscale structures and interaction with water. This distinguishes them from classical engineering materials, which are based on a selection and composition of chemical elements, which are often rare and environmentally unfriendly. The website of the corresponding research initiative can be found here.
