Review—Towards the Next Generation of Thermoelectric Materials: Tailoring Electronic and Phononic Properties of Nanomaterials

“…Different approaches, such as wet techniques, 2 blade-coating, 3 electrochemistry, 4 melting, 5 etc. have been used to modify the doping, 4 fabricate composites, 6 and tailor other characteristics that have been studied for their optimization and to understand how nanostructuring of organic materials affects their thermoelectric performance. Then, two conductive polymers, namely Poly(3,4-ethylendioxitiophene) (PEDOT) and Poly(3-hexylthiophene-2,5-diyl) (P3HT) will be described in detail, showing not only the advances obtained in their thermoelectric performance from a fundamental point of view, gaining a new insight into the behavior of such polymers, but also the implementation of device prototypes which show the potential of these materials.…”

Controlling dielectrical properties of polymer blends through defined PEDOT nanostructures

“…[26][27][28][29][30][31][32][33][34] However, considering the different results obtained for several nanocomposite systems, a high number of challenging questions remain unsolved.…”

Electromagnetic properties and performance of exfoliated graphite (EG) – Thermoplastic polyurethane (TPU) nanocomposites at microwaves

“…As an example, nanotubes were proven to allow a sufficient level of conductivity to manufacture components with antistatic properties which successfully started to appear in the market [8]. To the best of our knowledge, despite a number of papers dealing with electrical conductivity and percolation of graphene nanocomposites are available in literature [9,10,11,12], only few papers deal with the electromagnetic SE performance of such materials. Lianga and others in [13] studied the EMI shielding effectiveness in X-band (8.2-212.4 GHz) of solution-processable functionalized graphene (SPFG) in epoxy and showed that an interesting SE of -20 dB (which is the minimum value requested in commercial applications, ) can be obtained with 15 wt.% loading.…”
