| Abstract Scope |
Structuring of 2D materials and combining 2D materials with conventional materials such as metals and polymers can enable new functionalities and high performance by engineering exceptional and outstanding mechanical, electrical, and optical properties. The existing methods for synthesizing hybrid materials comprising graphene and metal NPs require complicated processes. We present a facile and rapid laser photothermochemical processing method to produce 3D porous graphene as well as a nanoassembly of 3D porous graphene and PdNPs from polymer films. Multi-dimensional hybrid nanomaterials combining 3D graphene and 1D metallic nanoparticles are produced in large scale with low production cost by transient laser photothermal processing. The nanohybrid material showed outstanding crystallinity, structural homogeneity with uniform NP sizes and distribution, and large surface area resulting from the hierarchical multiscale pore structure, allowing ultrahigh sensitivity hydrogen sensing with outstanding mechanical reliability, flexibility, and durability upon bending and twisting. |
