项目摘要

The influence of the surface modification of pressure-sensitive adhesive tapes on their adhesion behavior has been investigated. PBA [poly (butyl acrylate)] and PIB [poly (isobutylene)] adhesives were chosen as pressure-sensitive adhesives. Nitrogen and oxygen plasmas were used for the surface modification of the adhesives. The nitrogen plasma treatment showed large effects on the adhesion behavior of both the PBA and the PIB adhesives : The nitrogen plasma treatment led to decrease in the peel force for the PBA adhesive/stainless steel joint by 57 times, and increase for the PIB adhesive/stainless steel joint by 2.2 times. There are essential differences in the modification reactions caused by the nitrogen plasma between the PBA and PIB adhesives. Cross-linking reactions occurred in the PBA system, and on the other hand, degradation reactions occurred in the PIB system.The oxygen plasma treatment led to the formation of functional groups such as various carbonyl groups. The carbonyl formation was restricted to the topmost layer (50-300 nm) form the surface. The peel strength was closely related to the amount of carbonyl groups on the surface.From these results, we can conclude that surface modification of pressure-sensitive adhesive by plasmas can widely alter the adhesion behaviors. The details of the results were presented in the Symposium on Adhesion, which was held in New Orleans, on Aug.26, 1999. Also the details were published in Journal of Adhesion Science ＆ Technology, vol.13, p.573-592 (1999) and Journal of Applied Polymer Science, vol.78, p.1392-1401 (2000).

已经研究了压力敏感胶带对其粘合剂行为的表面修饰的影响。选择PBA [poly（丁基丙烯酸）]和PIB [聚（异丁基）]粘合剂作为压力敏感性粘合剂。氮和氧等离子体用于粘合剂的表面修饰。氮血浆处理对PBA和PIB粘合剂的粘附行为显示出很大的影响：氮血浆处理导致PBA粘合剂/不锈钢接头的果皮降低57倍，并增加了PIB粘合剂/不锈钢钢连接的含量，增加了2.2次。 PBA和PIB粘合剂之间的氮血浆引起的修饰反应存在基本差异。 PBA系统中发生了交联反应，另一方面，PIB系统中发生降解反应。氧血浆处理导致形成了官能团，例如各种羰基。羰基的形成仅限于表面最上层（50-300 nm）。果皮强度与表面上的羰基的量密切相关。从这些结果中，我们可以包括血浆对压力敏感性粘合剂的表面修饰可以广泛改变粘合剂行为。结果的详细信息在1999年8月26日在新奥尔良举行的有关粘附的讨论会上介绍。详细信息也发表在《粘附科学与技术杂志》上，第13卷，第13期，第573-592页（1999年）和应用聚合物科学杂志和杂志。
