Over the past decades, poly(3,4-ethylenedioxythiophene):polystyrene sulfonate (PEDOT:PSS) has emerged as one of the most attractive conducting polymers for organic electronics. In particular, PEDOT:PSS based composites have demonstrated its high potential as thermoelectrics. In this review, we aim to summarize the latest developments of PEDOT:PSS-based composite materials focusing on PEDOT:PSS/carbon nanostructures composites, PEDOT:PSS/tellurium composites, PEDOT:PSS/alloy composites, PEDOT:PSS/two-dimensional additives composites. The effects of various nanostructures such as nanoparticles, nanotube, nanowires and nanosheets on the thermoelectric properties of PEDOT:PSS was compared and discussed. The role of inorganic materials such as high-performance thermoelectric telluride-based alloys and certain two-dimensional materials e. g. SnSe, MoS₂, as dopants in enhancing the thermoelectric properties of PEDOT:PSS composites was reviewed. The recent advances of post-treatment using some new chemical reagents such as dimethyl sulfone and sodium formaldehyde sulfoxylate to improve thermoelectric properties of PEDOT:PSS composites are also outlined. At the end, challenges and opportunities of PEDOT:PSS composites in enhancing the thermoelectric performance are commented.
