“Sticky Things” explores the fascinating science behind adhesion, uncovering why certain materials are inherently sticky. Delving into the realms of biology and materials science, the book explains the forces that govern stickiness in both natural and synthetic substances. Readers will discover how intermolecular forces and surface energy play crucial roles in determining whether a substance clings to another surface or itself. For example, the unique chemical composition of tree sap, a blend of resins and sugars, contributes to its remarkable adhesive properties. The book examines natural adhesives like honey and biological glues used by marine organisms, providing insights into how nature has optimized adhesive solutions through evolutionary processes. By studying these examples, the book highlights how scientists can draw inspiration from nature for technological innovation, a concept known as biomimicry. Progressing from fundamental principles to specific examples, “Sticky Things” begins with an introduction to surface energy and wetting before exploring case studies of glue, honey, and tree sap. It concludes with a discussion of practical applications, from developing new coatings to creating biomedical materials.
