basic information
**Course Objectives and Aims** Surface processing of wood, plastic, and metal products is a crucial technology for enhancing product decoration or surface functions (such as hardness, wear resistance, hydrophilicity, and water repellency). In this processing, crosslinking reactions of polymers are often utilized. This is because crosslinking improves the mechanical properties, wear resistance, heat resistance, and solvent resistance of polymers. Until now, the focus has primarily been on crosslinking through thermal reactions. However, recently, surface processing using light (UV) has gained attention. This technology is interesting from the perspectives of environmental conservation, energy saving, and high-speed processing. Furthermore, this technology has also begun to be applied to photoresists in microfabrication. Nevertheless, crosslinked polymers are inconvenient from the perspective of reuse, and recently, the decomposition reactions of crosslinked polymers have started to be examined from the viewpoint of recycling (re-dissolution). In this course, we will not only introduce the basic thermal and photochemical crosslinking reactions used in surface processing but also explain how to utilize these crosslinking reactions from an application standpoint. Additionally, we will discuss the decomposition of crosslinked polymers from the recycling perspective.
