CVD nanocrystalline multilayer graphene coated 3D-printed alumina lattices

3D printing technologies have expanded the possibilities of fabricating new composite materials with tailored properties, which depend on both selected and structural design at multiple length scales. Here, a catalyst-free CVD method has been used to produce hybrid based printed cellular ?-Al2O3 substrates decorated by either nanocrystalline graphene or graphitic films tunable number layers. Graphene-based coatings variable thickness crystallinity controlled alteration parameters processing, performed under CH4/H2 flux. Transmission electron microscopy confirmed effective growth layers scaffolds due penetration gases into open pores. The fully-connected highly conductive pathways displayed room temperature electrical conductivity in range 101–103 S m?1. Furthermore, thermal also increased 50% for specimen 20 nm thick coating as compared bare ceramic scaffold. developed structures up expanding field application graphene/ceramic composites conditions requiring dielectric various shapes coated graphene-based catalytic supports good stability.
