Mechanical characterizations of cast Poly(3,4-ethylenedioxythiophene):Poly(styrenesulfonate)/Polyvinyl Alcohol thin films

Wide range high speed relative humidity sensor based on PEDOT:PSS–PVA composite on an IDT printed on piezoelectric substrate

“…These little irregularities in the overall uniform film were an expected result [31]. The bright cubes indicate the presence of PSS in that area [30].…”

“…The effect of doping polyvinyl alcohol (PVA, a well-known hydrophilic insulating polymer) with poly(3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS, the famous conductive polymer) on the mechanical properties of the thin film has been studied [30]. The chemical characterization has been done in [31] while the electrical characterization of the above mentioned composite with the doping of MgBr 2 has been studied in [32].…”

Impedance spectroscopy study of conducting polymer blends of PEDOT:PSS and PVA

“…However, pure PEDOT:PSS is mechanically brittle and for this reason must be blended to increase ductility. For example, PEDOT:PSS can be blended with polyvinyl alcohol (PVA) to enhance its mechanical properties and improve processing [19]. PVA (polyvinyl alcohol), a water soluble synthetic polymer, has excellent film forming, emulsifying, and adhesive properties [20].…”

A novel nano-Sn particle/poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate)/poly(vinyl alcohol) core–shell hierarchical composite as high-performance anode material for lithium ion batteries

“…In addition, the PEDOT:PSS coating layer is probably cracked by mechanical stress induced by large volume change of anode materials during cycles, affecting the electrochemical performance of anode electrodes. It is reported that poly(vinyl alcohol) (PVA) possesses excellent film-forming, emulsifying and adhesive properties for the presence of hydroxyl groups [23,24]. When used as an additive in a PEDOT:PSS system, the mechanical properties of the PEDOT:PSS matrix can be impressively enhanced due to the interactions between the hydroxyl groups in PVA and the functional groups in PED-OT:PSS matrix [24].…”

“…It is reported that poly(vinyl alcohol) (PVA) possesses excellent film-forming, emulsifying and adhesive properties for the presence of hydroxyl groups [23,24]. When used as an additive in a PEDOT:PSS system, the mechanical properties of the PEDOT:PSS matrix can be impressively enhanced due to the interactions between the hydroxyl groups in PVA and the functional groups in PED-OT:PSS matrix [24]. Meanwhile, the electrical conductivity of PEDOT:PSS matrix cannot drastically decrease due to a small amount of PVA [25].…”
