Hyperuniformes poröses anodisches Aluminiumioxid: ein 2D-Metamaterial mit verbesserten mechanischen Eigenschaften als Plattform für Zweischichtkomposit-Aktuatoren.
Hyperuniform disorder systems have already been found to have several applications in the fields of physics and materials science. They are also found in many natural and biological systems, such as the way that matter is distributed in the universe, as well as in the receptor organization patterns in the immune system and the photoreceptor patterns on avian eye retina. In addition, disordered hyperuniformity has led to major advances in the field of photonics. Because of their ability to control scattering properties, hyperuniform disordered structures have been used extensively to design complete photonic band gaps. Materials made of scatterers distributed on a hyperuniform point pattern can be transparent for a broad range of frequencies and directions of incidence. Finally, some groups have managed to design and manufacture hyperuniform disordered metamaterials and metasurfaces that possess peculiar properties, when compared to their conventional ordered counterparts. This proposal extends the concept to the fabrication of porous anodic aluminum oxide (AAO) membranes. The hypothesis, though not explicitly stated, is that hyperuniform disordered nanopores in AAO membranes may have enhanced mechanical properties. This idea has not been proposed before by other groups. The application is focused on the development of shape changing materials, where all investigators have extensive expertise and established lab equipment for the proposed work. The quality of this project is outstanding and it combines crossdisciplinary expertise including material process, characterization and testing.
