| Popis: | Pressure-sensitive adhesives (PSAs) are used in various industries, and have been widely applied in smart devices. In this study, the adhesion properties, viscoelastic properties, and gel fraction of PSAs were investigated after primary and secondary curing to understand their UV-curing behavior. In addition, the impact of concentration of crosslinking agent on the crosslinking density and the degree of crosslinking was investigated. In general, as more crosslinking agent was added, the hardness increased, but this result can be explained by the difference between “crosslinking density” and “degree of crosslinking” at the highest concentration of crosslinking agent actually led to a decrease in “degree of crosslinking”. |
