“…The optimized ratio of conductivity versus stretchability was obtained by adding 30 wt% PDMS‐ b ‐PEO, which surprisingly maintained the same conductivity as undoped PEDOT:PSS (≈0.3 S cm −1 ) and could be stretched up to 75%. PEDOT:PSS could also be blended with hydrophobic and rubbery poly( n ‐butyl acrylate‐styrene) (P(BA‐ r ‐St)) latex‐like elastomers to reach an elongation of 97% and a conductivity of 63 S cm −1 …”

The conductive polymer poly(3,4‐ethylenedioxythiophene) (PEDOT), and especially its complex with poly(styrene sulfonate) (PEDOT:PSS), is perhaps the most well‐known example of an organic conductor. It is highly conductive, largely transmissive to light, processible in water, and highly flexible. Much recent work on this ubiquitous material has been devoted to increasing its deformability beyond flexibility—a characteristic possessed by any material that is sufficiently thin—toward stretchability, a characteristic that requires engineering of the structure at the molecular‐ or nanoscale. Stretchability is the enabling characteristic of a range of applications envisioned for PEDOT in energy and healthcare, such as wearable, implantable, and large‐area electronic devices. High degrees of mechanical deformability allow intimate contact with biological tissues and solution‐processable printing techniques (e.g., roll‐to‐roll printing). PEDOT:PSS, however, is only stretchable up to around 10%. Here, the strategies that have been reported to enhance the stretchability of conductive polymers and composites based on PEDOT and PEDOT:PSS are highlighted. These strategies include blending with plasticizers or polymers, deposition on elastomers, formation of fibers and gels, and the use of intrinsically stretchable scaffolds for the polymerization of PEDOT.

“…As the mixture was coated on the substrates and drying via heating, the PEDOT:PSS polymer and P(St-BA) particles would be gathered together as the water evaporated, developing a PEDOT:PSS polymer surrounded P(St-BA) particles aggregation. While being exposed under rather high temperature at 60 C, the P(St-BA) with relatively low T g (À8 C) started to fuse together, however, the surrounded PEDOT:PSS polymer without an obvious T g still be rigid [16]. Thus, after the fusion and film forming process of P(St-BA) particles, the PEDOT:PSS network would be preserved.…”

“…In our previous work [16], we had prepared a serious of flexible conductive PEDOT:PSS based material by simply blending PEDOT:PSS dispersion with rubbery poly(styrene-r-butyl acrylate) P(St-BA) latex. For further study, this elastic PEDOT:PSS/P(St-BA) composite was applied on the PET-nonwoven fabric substrates.…”

“…[16][17][18][19] Chiu et al designed highly exible PEDOT:PSS-P(styrene-co-butyl acrylate) (P(St-BA)) dispersions by using PEDOT:PSS as stabilizer for P(St-BA) latex, but the P(St-BA) latex were micro-sized range with polydispersity due to the weak stabilizing capability of PEDOT:PSS. 20,21 Chiu et al also designed PEDOT:PSS-(P(St-BA)) dispersions by applying dodecylbenzene sulfonic acid (DBSA) as surfactant. 22 However, one disadvantage of these polymer blended lm is the decrease in conductivity with increasing amounts of insulating polymer.…”
