Show Abstract
The fabrication of macroscopic and multi-scaled assemblies (such as sponges, foams, aerogels) from Graphene and related 1D and 2D nanomaterials is an extensively studied field due to their broad range of applications, such as in bioelectronics, energy storage, catalysis as well as environmental protection. However, transferring the nanoscopic functionality of these low dimensional materials into the macroscopic world is still challenging to achieve. In my talk I demonstrate new approaches for the synthesis of cm3-sized multi-scaled framework architectures, composed of 1D and 2D nanomaterials, such as Graphene, MXenes, Carbon Nanotubes [1] and hexagonal boron nitride (h-BN) [2]. With porosities in the order of 99.99% and densities as low as 0.2 mg/cm3 the properties of these so-called aeromaterials are determined by the nanoscopic functionality of the source material, resulting in a unique set of electrical, thermal, optical and mechanical properties. I will further highlight and discuss new applications that are enabled by different aero-materials, ranging from high-brightness and efficient laser-based light sources [2], electro-pneumatic micropumps and high-power actuators for soft-robotics [3], as well as bioinspired conductive composites for bioelectronics [4].
