| Summary: | 碩士 === 長庚大學 === 機械工程學系 === 98 === This paper reports a novel infrared assisted roller embossing technique for the rapid fabrication of polymeric diffusion films with dual-sided microstructures. A roll-to-roll embossing facility with infrared heating has been designed, constructed and tested in our laboratory. Metallic rollers bearing microstructures are fabricated using a tungsten carbide turning machine. They were then used to replicate the microstructure onto 0.5 mm thick PC and PET films in the experiments. During roller embossing, the rollers are heated by the infrared energy to melt the thermoplastic at the roller/film interface and thereby to replicate the microstructure. Under the proper processing conditions, plastic films with 90 degree cross-angle dual-sided microstructures can be successfully fabricated. The experimental results in this study suggest that infrared assisted roller embossing provides an effective way of fabricating microstructures onto plastic substrates. This would provide significant advantages in terms of a shorter cycle time as well as improved product quality.
