The results of practical implementation of new technology of nanoparticles transport for advanced material design and medical applications are presented. As model objects, porous piezoceramics, and ceramic matrix piezocomposites were chosen. Different types of polymeric microgranules filled and/or coated by metal-containing nanoparticles were used for pilot samples fabrication. Polymeric nano- and microgranules were examined using transmission and scanning electron microscopy as well as by EXAFS and X-ray emission spectroscopy. Polymeric nano- and microgranules, coated or filled with different chemicals, were introduced in raw ceramics powders with successive porous ceramics or composite fabrication processes. A pilot samples of nano- and microporous ceramics and composites based on different piezoceramics compositions (PZT, lead-potassium niobate and lead titanate) were fabricated and tested. Resulting ceramic matrix piezocomposites were composed by super lattices of closed or open pores filled or coated by nanoparticles of metals, oxides, ferromagnetics etc. embedded in piezoceramic matrix. Dielectric and piezoelectric parameters of a pilot samples were measured using piezoelectric resonance analysis method. New family of nano- and microporous piezoceramics and ceramic matrix piezocomposites are characterized by a unique spectrum of the electrophysical properties unachievable for standard PZT ceramic compositions and fabrication methods. The developed technology of nanoparticles fabrication and transport can be used also for advanced medical applications such as gene and drug delivery, cancer and neurodegenerative decease therapy etc.
