Unique and comprehensive book edited by acknowledged leaders on
biobased adhesives that will replace petroleum-based adhesives.

Audience
This book will interest materials scientists, adhesionists, polymer chemists, marine biologists, food and agriculture scientists, and environmentalists. R&D personnel in a slew of wide-ranging industries such as aviation, shipbuilding, railway, automotive, packaging, construction, wood bonding, and composites should find this book a repository of current and much-needed information.

Description
This book contains 23 chapters covering the various ramifications of biobased adhesives. The chapters are written by world-class scientists and technologists actively involved in the arena of biobased adhesives. The book is divided into three parts: Part 1: Fundamental Aspects; Part 2: Classes of Biobased Adhesives; and Part 3: Applications of Biobased Adhesives. Topics covered include: an introduction to biobased adhesives; adhesion theories and adhesion and surface issues with biobased adhesives; chemistry of adhesives; biorefinery products as biobased raw materials for adhesives; naturally aldehyde-based thermosetting resins; natural crosslinkers; curing and adhesive bond strength development in biobased adhesives; mimicking nature; bio-inspired adhesives; protein adhesives; carbohydrates as adhesives; natural polymer-based adhesives; epoxy adhesives from natural materials; biobased polyurethane adhesives; nanocellulose-modified adhesives; debondable, recyclable, and biodegradable biobased adhesives; 5-Hydroxymethylfurfural-based adhesives; adhesive precursors from tree-derived naval stores; and applications in various diverse arenas such as wood bonding, controlled drug delivery, and wearable bioelectronics.

Author / Editor Details
Manfred Dunky, PhD, has spent a 40-year career in the chemical and wood-based panels industry as a researcher and consultant. During the last 25 years, he has placed an emphasis on adhesives based on natural resources. Besides his industry career, in 2000 he received his habilitation (post-doctoral lecturing qualification) for “Wood Science with special consideration of wood-based panels” and was a lecturer at several universities. He is invited regularly to speak at many wood science conferences.

Kashmiri Lal Mittal was employed by the IBM Corporation from 1972 through 1993. Currently, he is teaching and consulting worldwide in the broad areas of adhesion, as well as surface cleaning. He has received numerous awards and honors, including the title of doctor honoris causa from Maria Curie-Skłodowska University, Lublin, Poland. He is the editor of over 150 books dealing with adhesion measurement, adhesion of polymeric coatings, polymer surfaces, adhesive joints, adhesion promoters, thin films, polyimides, surface modification surface cleaning, and surfactants.
