项目摘要

Now fiber to the home is advancing so fast and therefore development of highly moisture durable optical adhesives for optical devices is very important issue to confirm the security and safety of high speed internet society. This project has been proceeded to develop bio-mimetic moisture durable adhesives by imitating the amino acid sequences of adherence protein of aquatic life which develop mechanical strength and water-fastness. The investigators are developing moisture durable optical adhesives using gelatine which has amino acid sequence like adherence protein of blue sea mussel. Peel strength of the gelatine was well maintained while currently used optical adhesives, Epotec 353ND, were deteriorated after 250 hrs under 85□-85% aging condition. They tried to improve the water-fastness by adding shell meal to gelatine. Recently, this project has developed highly moisture resistant optical adhesives by reconsidering monomer design and has compared the strength change between currentl … More y used one and newly developed one. They have reported that the possibility of ultra moisture resistant optical adhesives by the comparison of median time to failure(MTF) of adhesives deterioration under high temperature and high humidity test. MTF of newly developed cured adhesives deterioration was from several times to over 10 times longer MTF(over 3000 hrs) than the currently used one(ca. 300 hrs). Further, these newly developed adhesives were applied to the real optical devices under collaboration with three Japanese typical manufacturers. Their optical characteristics change, connection loss and reflection loss, were recognized to be well maintained under reliability tests. They report the good results of high temperature and high humidity test of adhesives themselves and the comparison of the results before and after the test of optical devices assembled with these adhesives. Also, they report favorable water immersion test results of optical devices assembled with the sib adhesives. Less

在光纤到户飞速发展的今天，开发用于光器件的高水分耐用光胶粘剂是确保高速互联网社会安全可靠发展的重要课题。本课题通过模仿水生生物黏附蛋白的氨基酸序列，开发具有机械强度和耐水性的仿生耐湿胶粘剂。研究人员利用具有类似于蓝贻贝粘附蛋白的氨基酸序列的明胶，开发了耐湿光学胶粘剂。目前使用的光学胶粘剂Epotec 353ND在85□-85%的老化条件下使用250小时后就会变质，而明胶的剥离强度保持得很好。他们试图通过在明胶中加入壳粉来提高其耐水性。近年来，本项目通过对单体设计的重新思考，研制出了高抗湿光学胶粘剂，并对目前使用的一种与新研制的一种的强度变化进行了比较。他们通过比较胶粘剂在高温高湿试验下劣化的中位失效时间（MTF），报道了超耐湿光学胶粘剂的可能性。新开发的固化胶粘剂劣化的MTF从目前使用的几倍到10倍以上（超过3000小时）。300小时)。此外，还与三家日本典型制造商合作，将新开发的胶粘剂应用于实际光学器件中。在可靠性测试中，它们的光学特性变化，连接损耗和反射损耗，都保持得很好。他们报告了粘合剂本身高温高湿测试的良好结果，以及用这些粘合剂组装的光学器件测试前后结果的比较。此外，他们还报告了用sib粘合剂组装的光学器件的良好的水浸测试结果。少
