Poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) and polydimethylsiloxane (PDMS) are typical conductive polymers and transparent elastomers, respectively, which are widely used in the field of stretchable electronics. This paper described a simple, cost-effective route for the preparation of PEDOT:PSS-PDMS conductive polymer films through direct manufacturing after miscibility. The surfactant, P-t octylophenol (Triton X-100), significantly improved the miscibility of PEDOT:PSS and ...

Solid polymer electrolyte (SPE) is an important part of printed electrochemical gas sensors and are of value to electrochemical sensors. Here, a new type of SPE was prepared by dissolving a poly-vinylidene fluoride (PVDF) matrix in a 1-methyl-2-pyrrolidone (NMP) to immobilize 1-ethyl-3-methylimidazolium tetrafluoroborate ([EMIM] [BF4]), which was then used in a new electrochemical amperometric nitrogen dioxide sensor. The SPE was coated on a single electrode and attached to the electrode to construct ...

In recent years, with the widespread application of stretchable electronic devices, the demand for high performance wearable strain sensors is increasing. We propose a simple strategy to prepare a stretchable composite conductor based on the good miscibility of polydimethylsiloxane (PDMS) and poly (3,4-ethylenedioxythiophene):poly (styrenesulfonate) (PEDOT:PSS) under doping. Although the addition of high concentration PEDOT:PSS can improve conductivity, it also reduces the mechanical properties and ...
