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.

The NFC-G sample preparation steps. The glass slide surface is treated by oxygen plasma (1) followed by spin coating of 5.0 wt% glycerol anchor layer (2), NFC-G spin coating (3), and PEDOT:PSS spin coating (4). The drop cast NFC-G samples were prepared by an additional step before the PEDOT:PSS spin coating

Mentions: Figure 1 shows the two different approaches for the sample preparation with spin-coated and drop cast NFC-G mixture. The samples were spin coated (KW-4A, Chemat Technology Inc., USA) at different speeds depending on the material: 5.0 wt% glycerol (the anchor layer) at 1000 rpm for 60 s, NFC-G mixtures at 1000 rpm for 60 s and homogenized standard PEDOT:PSS (Clevios PH 500, Heraeus Holding GmbH, Germany) at 1500 rpm for 60 s. The additional drop cast NFC-G coatings on precoated NFC-G layer were prepared out of 200 μL NFC-G solution of a given strength and mixture ratio covering the substrate area completely from edge to edge and then left to dry for 24 h at room temperature (RT) of 24 °C and relative humidity (RH) of 50 %. All samples were left to dry for 15 to 60 min in between the coating steps, and no wet-on-wet coatings were applied at any stage of this work.Fig. 1
