Valtakari D, Liu J, Kumar V, Xu C, Toivakka M, Saarinen JJ - Nanoscale Res Lett (2015)

Bottom Line: Aqueous dispersion of conductive polymer poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate) ( PSS) was deposited on spin-coated and drop cast nanofibrillar cellulose (NFC)-glycerol (G) matrix on a glass substrate.The effects of annealing temperature, the coating method of NFC-G, and the coating time intervals on the electrical performance of the PSS were characterized.PSS on drop cast NFC-G resulted in 3 orders of magnitude increase in the electrical conductivity compared to reference PSS film on a reference glass substrate, whereas the optical transmission was only slightly decreased.

ABSTRACT

Unlabelled: Aqueous dispersion of conductive polymer poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate) (

Pedot: PSS) was deposited on spin-coated and drop cast nanofibrillar cellulose (NFC)-glycerol (G) matrix on a glass substrate. A thin glycerol film was utilized on plasma-treated glass substrate to provide adequate adhesion for the NFC-glycerol (NFC-G) film. The effects of annealing temperature, the coating method of NFC-G, and the coating time intervals on the electrical performance of the

Pedot: PSS were characterized.

Pedot: PSS on drop cast NFC-G resulted in 3 orders of magnitude increase in the electrical conductivity compared to reference

Pedot: PSS film on a reference glass substrate, whereas the optical transmission was only slightly decreased. The results point out the importance of the interaction between the

Pedot: PSS and the NFC-G for the electrical and barrier properties for thin film electronics applications.

Mentions: PEDOT:PSS aqueous dispersion coatings are typically annealed to increase their conductivity. Figure 2 shows the effect of annealing temperature on conductivity of the spin-coated PEDOT:PSS deposited on oxygen plasma-treated reference and glycerol-treated glass. The used annealing temperatures vary from 60 to 130 °C that are below the recommended drying temperature given by the polymer manufacturer of 130 °C. The PEDOT:PSS films become more stable above 80 °C, and the scatter in the measurement data decreases with the raising annealing temperature. On a pure glass substrate, the PEDOT:PSS reaches a sheet resistance minimum at the 80 °C annealing temperature.Fig. 2
