Fourier transform infrared spectroscopy (FTIR) studies indicate that functional groups containing oxygen atom in both polymers have interacted with each other. Complexation between the polymer hosts and dopant salt is confirmed from the shifting of hydroxyl band and SCN- band. Phenomena of ion association and ion dissociation have been analysed by deconvoluting the FTIR band between 2030 and 2090 cm�1. Sample with 40 wt NH4SCN achieves the highest ambient conductivity of (1.45 ± 0.51) � 10-4 S cm-1. It is inferred that the conductivity is mainly governed by the diffusion coefficient and mobility of charge carriers. It is found that the increase in conductivity is accompanied by a decrease in the glass transition temperature (Tg). The variation of conductivity can be verified by the results from field emission scanning electron microscopy (FESEM). © 2020, Springer-Verlag GmbH Germany, part of Springer Nature. date: 2020 publisher: Springer Science and Business Media Deutschland GmbH official_url: https://www.scopus.com/inward/record.uri?eid=2-s2.0-85090867769&doi=10.1007%2fs11581-020-03753-9&partnerID=40&md5=12aded131639877bd75f90fb6e76297c id_number: 10.1007/s11581-020-03753-9 full_text_status: none publication: Ionics volume: 26 number: 12 pagerange: 6083-6093 refereed: TRUE issn: 09477047 citation: Shamsuri, N.A. and Zaine, S.N.A. and Yusof, Y.M. and Yahya, W.Z.N. and Shukur, M.F.
