Carbide Bonded Graphene Coating on Silicon Mold for Precision Glass Molding
نویسندگان
چکیده
The severe adhesion between silicon and glass has limited its application as mold material in precision glass molding. In this paper, a novel coating approach to create non-stick silicon mold for glass molding was introduced by using carbide-bonded graphene, a two dimensional material with a patterned atomic structure. A graphene coated silicon mold was fabricated using a coating process developed in house. Characterizations of coating reveal extraordinary mechanical properties. A glass sample with micro wells was successfully fabricated using a graphene coated silicon mold. This research demonstrated the functionality of the graphene coating. This newly developed process enables the use of silicon as mold material to fabricated sophisticated structures and high precision dimensions on glass which were not previously available. The result from this study will greatly improve precision glass molding.

Compression molding process can potentially be used to make high precision glass lenses. In a lens molding process, glass raw material is heated above its transition temperature and is subsequently pressed between the two mold halves into a lens shape. Controlled cooling (annealing) of the formed lens is then carried out with the molds in a closed position in order to enable uniform cooling of ...

متن کاملPhotonic bandgaps of conformally coated structures
Polymeric molds of the layer-by-layer photonic crystal can be economically synthesized with a microtransfer molding technique. The refractive indices of these molds are low, preventing formation of a photonic bandgap. We find that such molds can be conformally coated with higher-index material. Photonic band calculations find structures in which conformally coated layer-by-layer molds have comp...
