In this context, the present study aims at fabricating polyelectrolyte nanocomposite membranes based on poly(bis[2-(methacryloyloxy)ethyl] phosphate) [P(bisMEP)] and BC via the in-situ free radical polymerization of bis[2-(methacryloyloxy)ethyl] phosphate (bisMEP) inside the BC three-dimensional network under eco-friendly reaction conditions. The resulting polyelectrolyte nanocomposites exhibit thermal stability up to 200 \u00b0C, good mechanical performance (Young\u2019s modulus &gt; 2 GPa), water-uptake ability (79\u2013155%) and ion exchange capacity ([H+] = 1.1\u20133.0 mmol g\u22121). Furthermore, a maximum protonic conductivity of ca. 0.03 S cm\u22121 was observed for the membrane with P(bisMEP)\/BC of 1:1 in weight, at 80 \u00b0C and 98% relative humidity. The use of a bifunctional monomer that obviates the need of using a cross-linker to retain the polyelectrolyte inside the BC network is the main contribution of this study, thus opening alternative routes for the development of bio-based polyelectrolyte membranes for application in e.g., fuel cells and other devices based on proton separators.<\/jats:p>","DOI":"10.3390\/app8071145","type":"journal-article","created":{"date-parts":[[2018,7,16]],"date-time":"2018-07-16T04:05:33Z","timestamp":1531713933000},"page":"1145","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":49,"title":["Poly(bis[2-(methacryloyloxy)ethyl] phosphate)\/Bacterial Cellulose Nanocomposites: Preparation, Characterization and Application as Polymer Electrolyte Membranes"],"prefix":"10.3390","volume":"8","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9212-2704","authenticated-orcid":false,"given":"Carla","family":"Vilela","sequence":"first","affiliation":[{"name":"Department of Chemistry, CICECO-Aveiro Institute of Materials, University of Aveiro, 3810-193 Aveiro, Portugal"}]},{"given":"Ana P.
