利用UVNIL公司的玻璃碳母模制作了蛾眼结构的复型模。采用了一种新的高硬度、高耐候性的UV固化树脂。通过使用用于UV-NIL的常规UV固化树脂从复制模具复制蛾眼结构。与使用传统不含脱模剂的紫外线固化树脂的复制模相比，新型复制模的蛾眼结构具有上级的压印耐久性。对于第350次压印，压印膜的反射率低于1%。结果表明，复合材料的耐高温性能对提高复模的使用寿命至关重要。
Moth-eye-structure replica mold was fabricated from a glassy carbon master mold by UVNIL. New UV curable resin with high hardness and antifouling property was used. The motheye-structure was duplicated from the replica mold by use conventional UV curable resin for UV-NIL. Compared with the replica mold by use of a conventional release-agent-free UV curable resin, the moth-eye-structure of new replica mold had superior imprint durability. The reflectance of the imprinted film was below 1% for the 350th imprint. It was that the antifouling property was very important for prolonging life time of replica mold.
