Thermoelectric Properties and Thermal Stability of PEDOT:PSS Films on a Polyimide Substrate and Application in Flexible Energy Conversion Devices

Effective Approaches to Improve the Electrical Conductivity of PEDOT:PSS: A Review

“…[ 80 ] The hydrophilic nature of PSS and the hydrophobic nature of PEDOT offer a means for selective de-doping of PSS through the use of hydrophilic solvents such as EG. Kim et al prepared PEDOT:PSS fi lms by adding DMSO (or EG) into the PEDOT:PSS (Clevios PH 1000) aqueous solution and subsequent treatment [32] 7 × 10 −2 73 Cruz-Cruz et al [33] 10 −2 130 Wilson et al [34] 0.8 ± 0.1 80 ± 30 Kim et al [8] 0.2 (Clevios PH 510) 300 Wang et al [35] 0.2 (Clevios PH 500) 526 Na et al [36] <1 (Clevios PH 500) 550 Na et al [37] 0.2-1(Clevios T PH1000) 600 Hokazono et al [38] 0.2 (Clevios PH 1000) 670. 5 Lim et al [39] 0.2-1 (Clevios P) 677 Lee et al [40] 9 (Clevios P) 48 Jiang et al [41] 39 (Clevios P) 298 Liu et al [42] EG 2.2 × 10 −2 1.3 Dimitriev et al [32] 0.4 (Clevios P) 160 Ouyang et al [43] 0.4 200 Ouyang et al [19] 0.4 (Clevios PH 500) 443 Yan et al [44] 9 55 Jiang et al [41] 39 242 Liu et al [42] 15.64 274.…”

“…[ 42,59,88,113,148 ] Inspired by the achievements, more and more efforts have been made to enhance the ZT values of PEDOT:PSS, and the value was signifi cantly increased to 0.42 by Kim et al, [ 82 ] which was the highest value among those of organic TE materials. Furthermore, Hokazono et al [ 38 ] successfully prepared a fl exible device composed of the PEDOT:PSS fi lm on a polyimide substrate functioned as a micro thermoelectric generator, as presented in Figure 17 a. Assuming an optimum packing density of the legs of the device, the electrical power generation was estimated as 56.8 µW cm −2 at ΔT = 100 K (Figure 17 b).…”

Mechanical behavior of strain sensors based on PEDOT:PSS and silver nanoparticles inks deposited on polymer substrate by inkjet printing

“…On the other hand, piezoresistive sensors based on PEDOT:PSS can be used as strain sensors for various applications, also in the biomedical and health fields, due to its high biocompatibility [19]. Thermal and electrochemical stability and its high transparency [20] make PEDOT:PSS an interesting material, which also presents a certain versatility, such as the possibility of deposition on different substrates. Some examples of sensors manufactured with PEDOT:PSS deposited by inkjet printing are reported in Refs.…”
