On the project
Nízkohustotní funkční nanokompozity
Description in English
Materials tend to be either structural or functional. Here we propose to combine both aspects using hierarchical polymer nano-composites (PNCs) foamed in-situ with environmentally benign supercritical CO2 directly in the deposition zone of the additive manufacturing nanotechnology (AMN). This breakthrough AMN will yield lightweight solids with multi length scale programmable hierarchical structure, customizable shapes and tunable mechanical response. By selection of polymers, nanoparticles, PNC composition, nanoparticle spatial organization, interfacial attraction, foaming process and AMN parameters, advanced low density materials will be fabricated exhibiting simultaneous enhancement of stiffness, strength, toughness and thermal stability. Selecting functional NPs will introduce additional functions such as electrical conductivity, super-hydrophobicity, reduced flammability, large scale self-healing, etc. Their application areas include impact protection of space structures, deep sea thermal insulation, integral car body panels, EMI shielding and low pressure hydrogen storage.
