Recently, the University of California, Irvine, Hughes Research Laboratories (HRL) Ltd. and California Institute of Technology have jointly developed the lightest material in the world, with a density of only 0.9 mg/cm3, which is 100% lighter than Styrofoam. Times. Related papers were published in the November 18 issue of Science. Ultra-light (less than 10 milligrams per cubic centimeter) porous materials have great applications in acoustic insulation, battery electrodes, catalyst supports, acoustics research, shock energy buffering and so on. The new material has a unique "micro-lattice" porous structure, and even at the nanometer, micron, and millimeter scales, the composition is about 99.99% air and 0.01% solids, the lightest material Set a new limit. Lorenzo Wardvett, the project's principal researcher and the mechanical and aerospace engineer at the University of California, Irvine, said: "When the material size is as small as nanoscale, it will become stronger. Combining this nature, let microsquad become Can be tailored to get a unique microporous material." The researchers explained that the new ultra-light material is a circular hollow tube micro-frame structure, divided into three levels of nanometers, micrometers, and millimeters. First, a prototype of a self-accelerating photopolymer waveguide model is used to make a prototype, and then an electroless nickel coating is applied, and then the template is etched away. The resulting metal micro-slat structure has a density greater than or equal to 0.9 mg/cc. It is fully recovered after being compressed more than 50%. Its energy absorption performance is similar to that of the artificial rubber, and it is lighter than the ultra-light aerogel and carbon nanotube foam. “The key to making this material is to connect to a sash structure with a hollow tube 1000 times thinner than the hair,†said the paper’s lead author, Tobias Chandler, the HRL lab. William Carter, director of building materials at HRL Labs, also compared this new material with the large building materials in life: “Modern buildings with the Eiffel Tower or the Golden Gate Bridge as a typical example, their materials are extremely light, and their load-bearing effect Thanks to the support of the structure, we have introduced nano and micro concepts into new materials, which are innovations in lightweight materials."
