A team of researchers from the University of Hamburg has developed a novel 3D printing process for nanoparticle-based aerogels that could result in a new generation of photothermal devices.
Based on Direct Ink Writing (DIW) 3D printing, the technique offers new levels of design freedom for fabricating solar steam generation or thermochemical heat storage devices from titanium dioxide (TiO2) nanoparticle-based aerogels.
While TiO2 was used as the basis for the study, the researchers say their technique can also be generalized for a “broad material library” and allow nanoparticle inks to be designed with specific functionalities that can be adapted to their target applications.
