报告内容摘要：

  Integrating functional nanomaterials, such zero-dimensional (0D) metal oxide nanoparticles and two-dimensional (2D) nanosheets, into three-dimensional (3D) structures is highly desirable for developing advanced energy conversion/storage and electronic devices, yet remains as a significant challenge. Extrusion-based 3D printing, also known as direct-ink-writing (DIW) method, is a powerful manufacturing technique for the fast fabrication of complex 3D structures, which enables a high degree of freedom in structure design and reduces waste material and thus cost-effectiveness, etc. Therefore, 3D printing could pave the way for the practical applications of various nanomaterials by providing bridges between nanoscale materials and macroscale devices. However, how to simultaneously achieve both high mechanical strength and desirable macro- and microstructures in a 3D printed material remains a challenging scientific and engineering issue. As an example, assembly of 2D materials into vertically aligned structures is highly desirable (e.g. low tortuosity for rapid ion transport in fast charging-discharging batteries, guiding thermal transport for efficient thermal management), yet extremely challenging due to the energetically unfavorable in processing. In this talk, I will present some of our recent work in the last two years on how to printing functional nanomaterials into hierarchically porous or vertically aligned structures in multiscale. I will also discuss the applications of these 3D printed structures in energy conversion, electronics, and thermal management.
