The formation of RF crosslinks in the starch matrix was found to repress the starch\u2019s crystallinity as indicated by the XRD data. Incorporation of the RF plasticizer improved the conductivity greatly, with the highest room-temperature conductivity recorded being 4.29 \u00d7 10\u22124 S cm\u22121 achieved by the starch:LiTf:RF (20 wt.%:20 wt.%:60 wt.%) composition. The enhancement in ionic conductivity was an implication of the increase in the polymeric amorphous region concurrent with the suppression of the starch\u2019s crystallinity. Chemical complexation between the plasticizer, starch, and lithium salt components in the electrolyte was confirmed by FTIR spectra.<\/jats:p>","DOI":"10.3390\/polym12092170","type":"journal-article","created":{"date-parts":[[2020,9,24]],"date-time":"2020-09-24T03:03:39Z","timestamp":1600916619000},"page":"2170","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":25,"title":["Resorcinol-Formaldehyde (RF) as a Novel Plasticizer for Starch-Based Solid Biopolymer Electrolyte"],"prefix":"10.3390","volume":"12","author":[{"given":"Vidhya","family":"Selvanathan","sequence":"first","affiliation":[{"name":"Solar Energy Research Institute (SERI), Universiti Kebangsaan Malaysia (UKM), Bangi 43600, Malaysia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mohd Hafidz","family":"Ruslan","sequence":"additional","affiliation":[{"name":"Solar Energy Research Institute (SERI), Universiti Kebangsaan Malaysia (UKM), Bangi 43600, Malaysia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mohammod","family":"Aminuzzaman","sequence":"additional","affiliation":[{"name":"Department of Chemical Science, Faculty of Science, Universiti Tunku Abdul Rahman (UTAR), Perak Campus, Jalan Universiti, Bandar Barat, Kampar 31900, Perak D.
