Keep up-to-date with the latest on adhesion and adhesives from an expert group of worldwide authors. The book series “Progress in Adhesion and Adhesives” was conceived as an annual publication and the premier volume made its debut in 2015. The series has been well-received as it is unique and provides substantive and curated review chapters on subjects that touch many disciplines. The current book contains nine chapters on topics that include multi-component theories in surface thermodynamics and adhesion science; plasma-deposited polymer layers as adhesion promotors; functional interlayers to control interfacial adhesion in reinforced polymer composites; hydrophobic materials, and coatings from natural sources; mechanics of ice adhesion; epoxy adhesives technology: latest developments and trends; hot-melt adhesives for automobile assembly; lifetime estimation of thermostat adhesives by physical and chemical aging processes; and nondestructive evaluation and condition monitoring of adhesive joints. Audience The volume will appeal to adhesionists, adhesive technologists, polymer scientists, materials scientists, and those involved/interested in adhesive bonding, plasma polymerization, adhesion in polymer composites, durability and testing of adhesive joints, materials from natural sources, and ice adhesion and mitigation.
