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: Figure 6 shows cross sections of the PEDOT:PSS samples with and without annealing together with the spin-coated reference PEDOT:PSS on the oxygen plasma-activated glass on top (a). The annealed samples are shown to the left in Fig. 6 with spin coating (b1) and drop casting (c1) and the corresponding samples without annealing to the right, spin coated (b2), and drop cast (c2). The spin coating causes film shrinkage due to compression and fast evaporation of water from the thin films. Furthermore, annealing causes shrinkage due to drying. The cross section samples for the SEM imaging are commonly freeze fractured in liquid nitrogen. Unfortunately, moisture absorbed from the surrounding air can cause sample swelling with hygroscopic materials. In Fig. 6, on the left (a1, b1, c1), all drying steps are present, whereas on the right (b2, c2), the drying steps were reduced to a minimum. Finally, the cross section samples to the right were fractured at room temperature without freezing.Fig. 6
