The PHB films were prepared using a solvent casting process at temperatures ranging from 80\u2009\u00b0C to 160\u2009\u00b0C. The crystallinity, mechanical properties and surface morphology of the films cast at different temperatures were characterized and compared to PHB films cast using chloroform as a solvent. Results revealed that the properties of the PHB film varied considerably with solvent casting temperature. In general, samples processed with acetic acid at low temperatures had comparable mechanical properties to PHB cast using chloroform. This acetic acid based method is environmentally friendly, cost efficient and allows more flexible processing conditions and broader ranges of polymer properties than traditional methods.<\/jats:p>","DOI":"10.1038\/srep17884","type":"journal-article","created":{"date-parts":[[2015,12,7]],"date-time":"2015-12-07T06:18:55Z","timestamp":1449469135000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":196,"title":["Tuning the properties of polyhydroxybutyrate films using acetic acid via solvent casting"],"prefix":"10.1038","volume":"5","author":[{"given":"Preetam","family":"Anbukarasu","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dominic","family":"Sauvageau","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Anastasia","family":"Elias","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2015,12,7]]},"reference":[{"key":"BFsrep17884_CR1","doi-asserted-by":"publisher","first-page":"53","DOI":"10.1002\/macp.1992.021930105","volume":"193","author":"Y Kumagai","year":"1992","unstructured":"Kumagai, Y., Kanesawa, Y. & Doi, Y.
