Enhanced Thermoelectric Performance of Single-Walled Carbon Nanotubes/Polyaniline Hybrid Nanocomposites

Qin Yao; Lidong Chen; Wenqing Zhang; Shengcong Liufu; Xihong Chen

Hybrid nanocomposites containing carbon nanotubes (CNTs) and ordered polyaniline (PANI) have been prepared through an in situ polymerization reaction using a single-walled nanotube (SWNT) as template and aniline as reactant. TEM, SEM, XRD, and Raman analyses show that the polyaniline grew along the surface of CNTs forming an ordered chain structure during the SWNT-directed polymerization process. The SWNT/PANI nanocomposites show both higher electrical conductivity and Seebeck coefficient as compared to pure PANI, which could be attributed to the enhanced carrier mobility in the ordered chain structures of the PANI. The maximum electrical conductivity and Seebeck coefficient of composites reach 1.25 x 10(4) S m(-1) and 40 microV K(-1), respectively, and the maximum power factor is up to 2 x 10(-5) W m(-1) K(-2), more than 2 orders of magnitude higher than the pure polyaniline. This study suggests that constructing highly ordered chain structure is a novel and effective way for improving the thermoelectric properties of conducting polymers.

Assembly of one-dimensional nanorods into Bi2S3 films with enhanced thermoelectric transport properties

Shengcong Liufu; Lidong Chen; Qin Yao; Chunfen Wang

Bismuth sulfide thin films have been assembled by cross-linkage nanorods on surface-functionalized Si substrate with self-assembled monolayers. Results of transmission electron microscopy and electron diffraction revealed that highly crystalline Bi2S3 nanorods grow along c-axis direction. Electrical transport properties including resistivity (0.02Ωcm), thermopower (−755μVK−1), and carrier mobilities (1100cm2V−1s−1) of the Bi2S3 films at 300K are found superior to those of previously reported Bi2S3 samples. The Bi2S3 films exhibit a maximum thermoelectric power factor (3.97×10−3Wm−1K−2) at 450K. The enhancement of thermoelectric properties mainly originates from highly crystalline and oriented nanostructures embedded in the Bi2S3 films.

A general strategy to bismuth chalcogenide films by chemical vapor transport

Zhengliang Sun; Shengcong Liufu; Riuheng Liu; Xihong Chen; Lidong Chen

Developing a low-cost, simple manufacturing process for highly efficient thermoelectric films is an intriguing topic for both chemists and materialists. In this work, a new strategy was introduced to synthesize bismuth chalcogenide films by chemical vapor transport on presynthesized Bi films, including Bi2Se3, Bi2Te3 and Bi2Te2.7Se0.3. Through delicate control of the chalcogen vapor pressure, highly qualified and (00l) oriented bismuth chalcogenide films, constructed by oriented nanoplates, were obtained. The (00l) orientation of the films will facilitate the transport of the carrier for bismuth chalcogenides. Thermoelectric properties of these films were also characterized. At room temperature, the power factors reach 3 μW cm−1 K−1, 18.7 μW cm−1 K−1, 24.6 μW cm−1 K−1 for Bi2Se3, Bi2Te3, Bi2Te2.7Se0.3 films, respectively. Besides, the average power factor of 31.2 μW cm−1 K−1 in the temperature range of 300–500 K for Bi2Te2.7Se0.3 films indicates the present chemical vapor transport process is a promising technique for thermoelectric films.

Enhanced Thermoelectric Properties of Bi0.5Sb1.5Te3 Films by Chemical Vapor Transport Process

Zhengliang Sun; Shengcong Liufu; Xihong Chen; Lidong Chen

Bi₀.₅Sb₁.₅Te₃ films were prepared by a novel chemical vapor transport process through delicate controlling the temperature of the substrate and vapor source. The power factor reaches 30 μW cm⁻¹ K⁻¹ at room temperature, which is much higher than the value of the Bi₀.₅Sb₁.₅Te₃ films prepared by other techniques. The enhancement of thermoelectric properties might be attributed to the higher carrier mobility (252 cm² V⁻¹ s⁻¹), coming from the effective interparticle contiguity of (00L) oriented nanoplates embedded in the present Bi₀.₅Sb₁.₅Te₃ films.

Enhancing thermoelectric performance of bismuth selenide films by constructing a double-layer nanostructure

Zhengliang Sun; Shengcong Liufu; Xihong Chen; Lidong Chen

A new nanostructure of double-layer thin films (DLTFs) has been introduced to Bi2Se3 as thermoelectric films through a facile one-step and low-temperature solution route. The Bi2Se3 DLTFs consist of a (001) orientational inner layer and a (110) orientational outer layer with controllable thicknesses. The controllable release of the precursor ion is critical to adjust the double-layer nanostructures. The maximum power factor of the Bi2Se3 DLTFs reaches 100 μW m−1 K−1, which is larger by 79% than the value for a single layer Bi2Se3 film.
