Firstly, the book presents the underlying fundamentals of supramolecular gels including the assembly mechanism and structures. Then it introduces different material systems including composite supramolecular gels, organogels, hydrogels, self-healing and graphene-based supramolecular gels as well as their emerging applications, such as sensors, actuators, biomedical and environmental applications. The book offers insights to design and character new versatile soft materials.
