Research and Development of Aquo-biomimetic Ultra Water Resistant Optical Adhesives

现在光纤到户的发展如此之快，因此开发用于光学设备的高耐湿性光学粘合剂对于确保高速互联网社会的安全和安全是非常重要的问题。本课题拟通过模仿水生生物粘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性胶粘剂。研究人员正在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耐湿性光学粘合剂。明胶的剥离强度保持良好，而目前使用的光学粘合剂Epotec 353 ND在85 - 85%老化条件下250小时后劣化。他们试图通过在明胶中加入贝壳粉来提高耐水性。最近，本项目通过重新考虑单体设计，开发了高耐湿性光学粘合剂，并比较了目前使用的光学粘合剂与传统的光学粘合剂之间的强度变化。 ...更多信息 y使用一个和新开发的一个。他们报道了通过比较高温和高湿测试下粘合剂劣化的中值失效时间（MTF）来确定超防潮光学粘合剂的可能性。新开发的固化粘合剂的MTF劣化比目前使用的MTF（约3000小时）长数倍至超过10倍。300小时）。此外，这些新开发的粘合剂被应用到真实的光学器件的合作下，与三个日本典型的制造商。它们的光学特性变化，连接损耗和反射损耗，被认为是在可靠性测试下保持良好。他们报告了粘合剂本身的高温和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的结果比较。此外，他们报告了用该SIB粘合剂组装的光学器件的有利的水浸测试结果。少

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
