Integrated manufacturing of REciclable multi-material COmposites for the TRANSport sector

The present invention protects a novel process for obtaining hybrid nanomaterials of hydroxyapatite (HAp) sequentially decorated with nanoparticles of silver and zinc oxide (HAp-Ag-ZnO); and of hybrid nanomaterials of HAp sequentially decorated with nanoparticles of zinc oxide and silver (HAp-ZnO-Ag), using an in situ sonochemical synthesis route. The process consists of two steps: 1) sonochemical synthesis of the hybrid nanomaterials and 2) drying the hybrid nanomaterials using the freeze-drying method. In the first step, silver and zinc oxide nanoparticles are sequentially synthesized in situ or the nanoparticles of zinc oxide and silver on a nanoscale HAp substrate. In the second step the freeze-drying method is used in order to obtain a powder with higher porosity. This process allows obtaining new ternary hybrid nanomaterials with higher level of complexity and hierarchical structure in less time, and employing a smaller number of steps and reagents than those found in the literature. Likewise, the hybrid nanomaterials obtained in this process possess outstanding antibacterial properties. Furthermore, it should be noted that the process of obtaining the hybrid nanomaterials described in the present invention is carried out under less extreme conditions compared to other methods involving the obtainment of inorganic materials. The present invention relates to the industrial sector of electronics, biomedical, automotive, aeronautical, aerospace, of the transformation of plastics, energy, environmental remediation, design of multifunctional materials, nanotechnology, among others.
