This paper describes a novel, multilayered hot embossing method for fabricating a microstructure pattern on various polymer substrates. The method involves a multilayered hot embossing process with three polymer substrates (polycarbonate, polymethyl methacrylate, and low-density polyethylene), three pieces of microstructured molds, and graphene-based heaters. Only one hot embossing step is required in which a microstructure pattern is directly fabricated onto the three polymer substrates. The total processing cycle time is less than that of the traditional hot embossing process. In this study, thin graphene-based heaters were fabricated and tested. A facility that integrates graphene-based heating and multilayered hot embossing was designed and implemented. Under the proper processing conditions, a hemispherical microlens array and a microcylinder array pattern were successfully fabricated on the three polymer substrates. Finally, the uniformity of embossing temperature and the ...

用于在各种聚合物基材上制造微结构图案的新型多层热压花工艺

本文介绍了一种新颖的多层热压花方法，用于在各种聚合物基材上制造微结构图案。该方法涉及多层热压花工艺，该工艺具有三个聚合物基材（聚碳酸酯，聚甲基丙烯酸甲酯和低密度聚乙烯），三个微结构模具和基于石墨烯的加热器。仅需要一个热压花步骤，在该步骤中将微结构图案直接制造到三个聚合物基材上。总的加工周期时间小于传统的热压花工艺。在这项研究中，制造并测试了基于石墨烯的薄加热器。设计并实现了将基于石墨烯的加热和多层热压花相结合的设施。在适当的加工条件下，在三个聚合物基板上成功制作了半球形微透镜阵列和微柱阵列图案。最后，压纹温度的均匀性和...
