“…To achieve this goal, an inorganic-organic nanomaterial based on tellurium nanowires (TeNWs) with single-wall carbon nanotubes (SWCNTs) added during growth is deployed. The nanostructured TE material is produced following a surfactant-assisted chemical reduction reaction based on previously well-established synthetic routes [ 47 , 48 , 49 ] with a few variations. The rationale behind this selection is to obtain enhanced performance through the combination of the TE properties of the two nanomaterials and flexibility at a film level via the use of highly durable SWCNTs.…”

The present study demonstrates, for the first time, the ability of a 10-ply glass fiber-reinforced polymer composite laminate to operate as a structural through-thickness thermoelectric generator. For this purpose, inorganic tellurium nanowires were mixed with single-wall carbon nanotubes in a wet chemical approach, capable of resulting in a flexible p-type thermoelectric material with a power factor value of 58.88 μW/m·K2. This material was used to prepare an aqueous thermoelectric ink, which was then deposited onto a glass fiber substrate via a simple dip-coating process. The coated glass fiber ply was laminated as top lamina with uncoated glass fiber plies underneath to manufacture a thermoelectric composite capable of generating 54.22 nW power output at a through-thickness temperature difference οf 100 K. The mechanical properties of the proposed through-thickness thermoelectric laminate were tested and compared with those of the plain laminates. A minor reduction of approximately 11.5% was displayed in both the flexural modulus and strength after the integration of the thermoelectric ply. Spectroscopic and morphological analyses were also employed to characterize the obtained thermoelectric nanomaterials and the respective coated glass fiber ply.

“…Furthermore, the electrical conductivities of these as-fabricated Te NWs thin pieces in this work are 1 to 3 orders of magnitude higher as compared to previously reported works (0.005-0.22 S cm À1 ). 15,[55][56][57][58] On the other hand, as observed in Fig. 3A-D, the S of the Te NWs thin pieces synthesized with glucose changed slightly under different reaction conditions.…”

“…4B, the electrical conductivity of the Te NWs thin pieces decreased with decreasing temperature for both glucose and N 2 H 4 ÁH 2 O-synthesized Te NWs, indicating typical semiconductor behavior. 58 To reveal the high electrical conductivity of Te NWs synthesized with glucose, we fitted the temperature-dependent conductivity of these Te NWs thin pieces before and after annealing with the 1D variable…”

Ever‐increasing packaging and power densities of modern electronic devices in the present “More‐than‐Moore” technology era demand higher performance thermal interface materials (TIMs). However, conventional composite TIMs require higher loading to achieve better thermal conductive property, resulting in a mechanical problem. The poor wetting property of matrix loading materials further increases the interfacial thermal resistance (ITR). In this work, a one‐step hydrothermal method is employed to grow 2D molybdenum disulfide (MoS2) nanosheets on a tellurium (Te) nanowire skeleton and silver (Ag) nanoparticles are further decorated on MoS2 nanosheets via the photoreduction method. The in‐plane thermal conductivity of the final nanocomposite reaches as high as 10.4 W m−1 K−1, which is 4,160% higher than that of a pure epoxy resin and one order of magnitude higher than that of conventional polymeric nanocomposites. The 3D interconnected heat transferring network of Te/MoS2/Ag greatly enhances the thermal stability of the composite in practical applications. The rational materials design concept may contribute to the development of new types of high‐performance thermal management materials.
