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.

Fig4: PEDOT:PSS sheet resistance on spin coated NFC-G samples with variable NFC concentration and spin coating parameters at a constant glycerol concentration of 5.0 wt%

Mentions: Figure 4 shows the PEDOT:PSS sheet resistances on a spin-coated NFC-G. We observe that PEDOT:PSS on 0.1/5.0 wt% NFC-G behaves similarly to the reference PEDOT:PSS spin-coated directly on a glass as shown in Fig. 2. The large standard deviations in the 60 and 80 °C points originate from the PEDOT:PSS instability that is absent in the 100 and 130 °C. Similar results indicate that the PEDOT:PSS and the NFC-G coatings act as separate, isolate entities with no interaction between the two layers during the spin coating or annealing.Fig. 4
