Understanding PEDOT doped with tosylate

Abstract

Now in their 5th decade of research and development, conducting polymers represent an interesting class of materials to underpin new wearable or conformable electronic devices. Of particular interest over the...

Injectable PEDOT:PSS/cholinium ionic liquid mixed conducting materials for electrocardiogram recordings

“…The weight ratio was calculated without considering the water of PEDOT:PSS dispersion, thus, the established weight ratios are the final mass ratio between PEDOT:PSS and IL mass in the dried composite. 42 In addition, a physical gel was obtained by mixing PEDOT:PSS and [Ch][Lac] at a weight ratio of 60/40 and allowing the sample to equilibrate at room temperature until gelation occurred.…”

Surface Doping in Poly(3,4-ethylenedioxythiophene)-Based Nanoscale Films: Insights for Polymer Electronics

“…These differences motivate the exploration of molecular- or atomic-anion-doped PEDOT. The candidate material of PEDOT:Tos is also of specific interest given the equivalent chemistry of Tos and PSS (Tos is the molecular variant of the polymeric PSS) yet results in different properties and behavior …”

“…The candidate material of PEDOT:Tos is also of specific interest given the equivalent chemistry of Tos and PSS (Tos is the molecular variant of the polymeric PSS) yet results in different properties and behavior. 10 Nanoscale films of PEDOT find application in devices such as solar cells and electrochemical transistors. The interface of PEDOT is particularly important because this is where it interacts with neighboring layers/materials or the surrounding environment.…”

Smart textiles for human–machine interface fabricated via a facile on-site vapor-phase polymerization

“…25 According to the different deposition methods, the final prepared PEDOT composition will be also slightly different, which is reflected in the choice of doping anions. 32 With the presence of poly(styrene sulfonate) (PSS), poly(3,4-ethylenedioxythiophene)-poly(styrene sulfonate) (PEDOT:PSS) exists in an aqueous processable state, 33 making the liquid-phase deposition technique the first choice. Researchers reported dip-coating PEDOT:PSS on natural and man-made fabric substrates.…”

“…38 Besides the effect of aqueous solution, the weak adhesion of polymers to textiles is another reason for the deterioration of a textile's properties. 32,39 Some additives have been used to improve the adhesion between PEDOT:PSS and fabrics, but most of these additives are insulating and can negatively affect the breathability and comfort of the fabrics. 40 Vapor-phase polymerization (VPP) is an effective technique to uniformly deposit PEDOT coatings on target substrates.…”
