Abstract

Adhesives are a class of substances that can join two or more substrates together, and the development of reusable adhesives has been favored by scientists in recent years. Some azo phenyl derivatives (Azo) can undergo photoisomerization after UV irradiation, reversibly converting from solids to liquids and returning to solids under visible light. During the photoisomerization process, the trans and cis-configurations of Azo exhibited significantly different melting point (Tm) and/or glass transition temperature (Tg), which provided a theoretical basis for the preparation of reversible adhesives at room temperature using Azo's photosolid-liquid transition. Focusing on the research of azo phenyl photophase change adhesives, this paper reviews the latest research progress of two types of azo phenyl photophase change adhesives, which points out the direction for the design and development of new azo phenyl photophase change adhesives.
