PEDOT:PSS polymer can improve optoelectronic device performance, but its chemical composition plays a key role in preventing shrinkage during polymerization. Adding additional PSS molecules to optimize the solution viscosity can help prevent shrinkage on the material when using PEDOT:PSS for polymerization.
Blending various soft poly(n-butyl acrylate–styrene) (P(BA–St)) latexes into a PEDOT:PSS conductive dispersion can help prevent shrinkage in the material. Altering solution parameters like pH, ionic strength, and counterion to the charges on the cellulose can tune the adsorbed amount of PEDOT:PSS, preventing shrinkage on the material.
Acid-treated PEDOT:PSS thin films exhibit improved charge transport behavior at low temperatures, potentially preventing shrinkage due to wave function shrinkage. Introducing PEGMA to the PSS copolymer improved mechanical properties and weather stability, preventing shrinkage on the material during polymerization.
Adding the FS-31 surfactant to PEDOT:PSS reduces the contact angle and improves wetting properties, preventing shrinkage on the material. A controlled addition process during the polymerization process can improve the linearity of PEDOT and the proportion of PEDOT attached to the PSS chain. Using a silicon nitride protection layer can help prevent shrinkage on PEDOT:PSS during polymerization
