Abstract Pressure-sensitive adhesives (PSAs) and UV-curable acrylic systems are widely utilized. In particular, PSAs have currently attracted significant attention because of their utility and applicability for manufacturing re-useable modules for smart devices. In this study, adhesion properties, UV-curing behavior, viscoelastic properties, and gel fraction were investigated. The UV/UV step curing process was utilized to overcome limitations, such as re-work or gap filling. The difference in physical properties between primary curing and secondary curing was confirmed. In addition, by adjusting the content of the crosslinking agent, the experiment based on controlling the structure of the semi-interpenetrating polymer network was conducted. We determined that physical properties varied with the crosslinking agent content. The degree of crosslinking was high, whereas the crosslinking density was low for 0.1–0.3 phr. However, both the degree of crosslinking and the crosslinking density increased for 0.5–1 phr.

使用半IPN结构和UV/UV逐步固化的丙烯酸PSA的行为和粘合性能

摘要 压敏粘合剂 (PSA) 和紫外线固化丙烯酸系统被广泛使用。特别是，PSA 因其在制造可重复使用的智能设备模块方面的实用性和适用性而目前引起了极大的关注。在这项研究中，研究了粘附特性、紫外线固化行为、粘弹性和凝胶分数。UV/UV 步进固化工艺被用来克服限制，例如返工或间隙填充。确认了一次固化和二次固化之间的物理性能差异。此外，通过调节交联剂的含量，进行了基于控制半互穿聚合物网络结构的实验。我们确定物理性质随交联剂含量而变化。交联度高，而交联密度低，为 0.1–0.3 phr。然而，交联度和交联密度均增加了 0.5–1 phr。
