Special Issue Information

Dear Colleagues,

Currently, large amounts of energy generated are dissipated as heat into the surrounding atmosphere. Thermoelectric materials which enable direct conversion from thermal energy into electricity are considered emerging candidates in harvesting waste heat. Driven by the rapid progress in wearable and miniaturized electronic devices over recent decades, flexible thermoelectric materials, especially polymer-based thermoelectric composites which can be integrated into wearable devices, have attracted special interest. Despite the advances achieved in pursuing high-performance thermoelectric polymer composites so far, we expect further steps forward through the physical–chemical, structural, electronic, and compositional study of polymer-based thermoelectric composites and their devices.

In this Special Issue, we aim to provide readers with up-to-date research advances in polymer composites for thermoelectric energy conversion. We invite researchers to contribute research articles, review papers, and communications including, but not restricted to, the following:

  1. High-performance thermoelectric polymer-based composites;
  2. Novel fabrication methods of thermoelectric composites;
  3. Physical/chemical study of thermoelectric composites;
  4. Thermoelectric composite fibers;
  5. Novel design of flexible thermoelectric devices.

Organic thermoelectric (TE) materials have been widely investigated due to their good stability, easy synthesis, and high electrical conductivity. Among them, polyaniline/carbon nanotubes (PANI/CNTs) composites have attracted significant attention for pursuing enhanced TE properties to meet the demands of commercial applications. In this review, we summarize recent advances in versatile PANI/CNTs composites in terms of the dispersion methods of CNTs (such as the addition of surfactants, mechanical grinding, and CNT functional group modification methods), fabrication engineering (physical blending and in-situ polymerization), post-treatments (solvent treatments to regulate the doping level and microstructure of PANI), and multi-components composites (incorporation of other components to enhance energy filtering effect and Seebeck coefficient), respectively. Various approaches are comprehensively discussed to illustrate the microstructure modulation and conduction mechanism within PANI/CNTs composites. Furthermore, we briefly give an outlook on the challenges of the PANI/CNTs composites for achieving high performance and hope to pave a way for future development of high-performance PANI/CNTs composites for sustainable energy utilization.
