“…The ZT can be simply achieved by a low thermal conductivity or with a high power factor (PF = S 2 •σ). Currently, conductive polymers such as poly(3,4-etylenedioxythiophene)-poly(4-styrenesulfonate) (PEDOT:PSS), polypyrrole, and polythiophene are being used as TE base materials because of their outstanding thermoelectric properties [21][22][23]. Ju et al enhanced the thermoelectric properties of a conductive PEDOT:PSS matrix by incorporation SnSe nanosheets [24].…”

We present hybrid organic inorganic materials, namely, SrTiO3/polyaniline (PANI) composites, with high thermoelectric performance; samples with various SrTiO3 contents (10, 20, 30, and 50 wt.%) were prepared. The PANI component was obtained through the polymerization of aniline monomers, followed by camphosulfonic acid-doping to enhance its electrical conductivity. SrTiO3, with a high Seebeck coefficient, was used as the N-type inorganic componenet; it was synthesized via a one-pot solvothermal methods and, then, dispersed into the conductive PANI matrix. The SrTiO3 content influenced the Seebeck coefficient and electrical conductivity of the resulting composites. The variations in the thermoelectric properties of the SrTiO3/PANI composites consequently changed their power factor; at room temperature, the highest value was ~49.6 μW·m/K2, which is 17 times larger than that of pure PANI.

The urgent demand for renewable energy has attracted widespread interest in polymer‐based thermoelectric materials due to easy fabrication, high flexibility, low toxicity, low thermal conductivity, and great potential in industrial applications. However, the power factors of the polymers are still quite low compared with those of their inorganic counterparts, resulting in a low energy conversion efficiency. Highly conductive carbon materials, including graphene and carbon nanotubes, have recently been incorporated into the polymer matrix through intrinsic chemical intimacy, providing new opportunities to tune the thermoelectric properties. In particular, the characteristic π‐π coupling and other interactions between the two components have contributed to unique mechanisms for better thermoelectric performance beyond the simple rule of mixtures. This paper aims to review the up‐to‐date progress in polymer/carbon nanocomposites along with various compositions and novel synthetic strategies. The salient aspects of this review are characteristic interactions and various mechanisms, which might result in enhanced thermoelectric properties and subsequent potential applications in energy harvesting, wearable electronics, photo‐thermoelectrics, and other devices.

Polyhydroxybutyrate (PHB) has been used in the biomedical field. However, the poor mechanical properties of PHB have limited its application. Here, electrospun fibrous nanocomposite mats reinforced with cellulose nanocrystals (CNCs) were fabricated by using PHB as polymeric matrix. The morphological, thermal, mechanical properties, as well as cytotoxicity were characterized. Increasing the concentration of CNCs caused a decrease in diameter of the electrospun fibers. Moreover, thermal analysis indicated that melting temperature of PHB/CNCs electrospun fibers were improved with the increased CNCs content. The addition of CNCs gradually enhanced the tensile strength till 8 wt % content followed by a gradual decrease at higher CNCs content (12–22 wt %) in tensile strength. The PHB/CNCs electrospun fibers were nontoxic to L‐929 and capable of supporting cell proliferation in all conditions. This study demonstrates that fibrous PHB/CNCs electrospun fibers are cytocompatible and potentially useful mechanical properties for biomedical application. © 2016 Wiley Periodicals, Inc. J. Appl.
