In this study, two types of metal salts were tested: copper (II) sulfate and iron (II) sulfate. The optimal condition to produce BC-PANI-metal salt membranes was 0.05% (w\/v) of copper (II) sulfate (copper salt). X-ray diffraction analysis showed that the crystallinity of BC-PANI increased after adding copper salt. According to the increased degree of crystallinity, the polymer chain structure of BC-PANI-copper salt (BC-PANI-Cu) was more organized than that of BC-PANI, as confirmed by scanning electron microscopy. In addition, this ordered structure of BC-PANI-Cu indicated enhanced electrical conductivity. Moreover, the addition of copper salt improved the electrical conductivity of BC-PANI to a level about 3.8 times higher than that of BC-PANI produced without metal salt, and it retained about 40% of its original electrical conductivity after three washing cycles. From the results, the addition of copper salt improved both the electrical conductivity and washing durability of the BC-PANI membrane. <\/jats:p>","DOI":"10.1177\/0040517519893717","type":"journal-article","created":{"date-parts":[[2019,12,17]],"date-time":"2019-12-17T04:33:17Z","timestamp":1576557197000},"page":"1517-1526","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":14,"title":["Production of conductive bacterial cellulose-polyaniline membranes in the presence of metal salts"],"prefix":"10.1177","volume":"90","author":[{"given":"Hyunjin","family":"Kim","sequence":"first","affiliation":[{"name":"Department of Clothing and Textiles, Sookmyung Women\u2019s University, Seoul, Korea"}]},{"given":"Ji","family":"Eun Song","sequence":"additional","affiliation":[{"name":"Human Convergence Technology Group, Korea Institute of Industrial Technology, Ansan, Korea"}]},{"given":"Carla","family":"Silva","sequence":"additional","affiliation":[{"name":"Center of Biological Engineering, University of Minho, Braga, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3456-8617","authenticated-orcid":false,"given":"Hye Rim","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Clothing and Textiles, Sookmyung Women\u2019s University, Seoul, Korea"}]}],"member":"179","published-online":{"date-parts":[[2019,12,16]]},"reference":[{"doi-asserted-by":"publisher","key":"bibr1-0040517519893717","DOI":"10.3390\/s140711957"},{"doi-asserted-by":"publisher","key":"bibr2-0040517519893717","DOI":"10.1080\/00405000.2012.664867"},{"doi-asserted-by":"publisher","key":"bibr3-0040517519893717","DOI":"10.1016\/j.synthmet.2009.03.021"},{"doi-asserted-by":"publisher","key":"bibr4-0040517519893717","DOI":"10.1016\/j.sna.2018.02.037"},{"doi-asserted-by":"publisher","key":"bibr5-0040517519893717","DOI":"10.1002\/app.10211"},{"doi-asserted-by":"publisher","key":"bibr6-0040517519893717","DOI":"10.1002\/pc.23588"},{"doi-asserted-by":"publisher","key":"bibr7-0040517519893717","DOI":"10.1016\/j.synthmet.2014.08.007"},{"issue":"12","key":"bibr8-0040517519893717","doi-asserted-by":"crossref","first-page":"11859","DOI":"10.1016\/S1452-3981(23)16509-6","volume":"7","author":"Molapo K","year":"2012","journal-title":"Int J Electrochem Sci"},{"doi-asserted-by":"publisher","key":"bibr9-0040517519893717","DOI":"10.1016\/j.progpolymsci.2008.02.002"},{"doi-asserted-by":"publisher","key":"bibr10-0040517519893717","DOI":"10.1016\/j.progpolymsci.2009.04.003"},{"doi-asserted-by":"publisher","key":"bibr11-0040517519893717","DOI":"10.1016\/j.synthmet.2013.06.004"},{"doi-asserted-by":"publisher","key":"bibr12-0040517519893717","DOI":"10.1016\/j.cap.2011.04.045"},{"doi-asserted-by":"publisher","key":"bibr13-0040517519893717","DOI":"10.3390\/jfb3040864"},{"doi-asserted-by":"publisher","key":"bibr14-0040517519893717","DOI":"10.1007\/s10570-012-9705-5"},{"doi-asserted-by":"publisher","key":"bibr15-0040517519893717","DOI":"10.1016\/j.cap.2018.05.008"},{"doi-asserted-by":"publisher","key":"bibr16-0040517519893717","DOI":"10.1007\/s10570-011-9565-4"},{"doi-asserted-by":"publisher","key":"bibr17-0040517519893717","DOI":"10.1016\/j.compscitech.2017.04.002"},{"doi-asserted-by":"publisher","key":"bibr18-0040517519893717","DOI":"10.1016\/j.progpolymsci.2013.08.009"},{"doi-asserted-by":"publisher","key":"bibr19-0040517519893717","DOI":"10.3144\/expresspolymlett.2017.14"},{"doi-asserted-by":"publisher","key":"bibr20-0040517519893717","DOI":"10.1016\/j.synthmet.2013.02.028"},{"doi-asserted-by":"publisher","key":"bibr21-0040517519893717","DOI":"10.1016\/j.mseb.2005.07.011"},{"doi-asserted-by":"publisher","key":"bibr22-0040517519893717","DOI":"10.1080\/00150193.2016.1258956"},{"doi-asserted-by":"publisher","key":"bibr23-0040517519893717","DOI":"10.1177\/0021998310376114"},{"doi-asserted-by":"publisher","key":"bibr24-0040517519893717","DOI":"10.1002\/smll.200400155"},{"doi-asserted-by":"publisher","key":"bibr25-0040517519893717","DOI":"10.1007\/s12034-014-0037-y"},{"doi-asserted-by":"publisher","key":"bibr26-0040517519893717","DOI":"10.1177\/0040517518763989"},{"doi-asserted-by":"publisher","key":"bibr27-0040517519893717","DOI":"10.1002\/elsc.201700085"},{"doi-asserted-by":"crossref","unstructured":"Mallick K, Witcomb MJ, Dinsmore A et al.
