Organic-inorganic hybrid thermoelectric materials through a new concept of simultaneous vapor phase coating and infiltration (VPI/SCIP)
The goal of HYTEM was to develop advanced organic-inorganic hybrid thermoelectric materials by applying a concept of vapour phase infiltration (VPI) of polymers with inorganics. I developed thermoelectric materials with chemically linked organic/inorganic interfaces. The originality and a main result of this work lies in a newly developed materials set, where hierarchical superlattice structures of different inorganic materials are simultaneously grown in the subsurface of a polymer and on its top (as shown on the logo of the project), which allowed to obtain a superior thermoelectric performance. The success of HYTEM is of great importance for the EU as it created new options for the waste-to-energy industry. This goal was reached through following three specific objectives (SOs): 1. VPI-synthesis of Me nanoparticles inside the polymer bulk. (WP1) 2. VPI/SCIP synthesis of a hybrid TE. (WP2) 3. Characterization of the material and its TE properties. (WP3)

Project objective
In a world of enormously rising energy consumption and environmental pollution, the demand for clean and renewable energy sources and for minimizing the energy loss is of critical importance. One strategy towards improved efficiency involves capturing and recycling the “waste” heat from all energy conversion processes. With a special class of materials, known as thermoelectrics, thermoelectric generators can be devised, which allow a direct conversion of heat into electricity. The goal of HYTEM is to develop advanced organic-inorganic hybrid thermoelectric materials by applying a newly developed concept of simultaneous vapour phase coating and infiltration (VPI/SCIP) of polymers with inorganics. SCIP is a viable, scalable and robust preparative strategy for obtaining high-performance hybrid superlattice TE materials with chemically linked organic/inorganic interfaces, which have never been demonstrated before. The originality of this work lies in creating a new hybrid materials set, where hierarchical superlattice structures of different inorganic materials are simultaneously grown in the subsurface of a polymer and on its top, which will allow to obtain a superior TE performance. An initial growth of inorganic nanoparticles inside a polymer bulk by infiltration will generate nanoscale point defects in the polymer, which will reduce the thermal conductivity of the matrix by inducing phonon scattering, while at the same time the electrical conductivity will be enhanced. To date, no work has been done to explore the potential of VPI/SCIP to generate hierarchical inorganic structuring in polymers. The knowledge gained from these experiments will have a great impact on the research of hybrid TEs due to the uniqueness of VPI/SCIP.
