The epoxidized oil (ECO) and presscake waste fibers (CP) recovered from post-oil extraction, were recombined for developing PLA functional biocomposites, according to \u201czero waste\u201d circular economy approach. Different compositions of PLA\/CP and PLA\/CP\/ECO were prepared in form of platelets and investigated by thermal, morphological, structural and mechanical analyses. The poor interfacial adhesion between the hydrophobic PLA matrix and short, hydrophilic and randomly dispersed presscake fibers, well evidenced by morphological analysis, was responsible of PLA thermal degradation hastening, Tg decreasing and\u00a0<a title=\"Learn more about tensile properties from ScienceDirect's AI-generated Topic Pages\" href=\"https:\/\/www.sciencedirect.com\/topics\/materials-science\/tensile-property\">tensile properties<\/a>\u00a0dropping down, since no mechanical stress transfer occurred from the polymer to the dispersed phase. The inclusion of ECO slightly improved the above properties due to its mild compatibilizing action inducing a fairly tightening of the\u00a0<a title=\"Learn more about macromolecular structure from ScienceDirect's AI-generated Topic Pages\" href=\"https:\/\/www.sciencedirect.com\/topics\/chemistry\/macromolecular-structure\">macromolecular structure<\/a>. The recycling of CP waste fibers was effective in hastening the polymer biodegradation in common soil under environmental conditions. Indeed, biocomposites recovered after 90 days of soil burial tests evidenced morphological features typical of late stage PLA biodegradation, a drastic dropping down of molecular weights and a decreasing of PLA thermal stability. These experimental evidences, not detected in soil buried neat PLA, assessed that the inclusion of CP waste fibers inside PLA matrix, represented a valid route to promote a fast and easy PLA biodegradation if compared to the composting method commonly used, for which severe atmosphere conditions and specific microbial population are necessary.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Biocomposites based on Poly(lactic acid), Cynara Cardunculus seed oil and fibrous presscake: a novel eco-friendly approach to hasten PLA biodegradation in common soil Rosa Turco, Domenico Zannini, Salvatore Mallardo, Giovanni Dal Poggetto, Riccardo Tesser, Gabriella Santagata, Mario Malinconico, Martino Di Serio Polymer Degradation and Stability, 2021, 109576\u00a0 https:\/\/doi.org\/10.1016\/j.polymdegradstab.2021.109576 Abstract Cynara Cardunculus\u00a0plant was used as source [&hellip;]<\/p>\n","protected":false},"author":2,"featured_media":1292,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[28,17],"tags":[],"class_list":["post-1291","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-biopolymers","category-publications"],"acf":[],"_links":{"self":[{"href":"https:\/\/nicl.it\/new\/wp-json\/wp\/v2\/posts\/1291","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/nicl.it\/new\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/nicl.it\/new\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/nicl.it\/new\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/nicl.it\/new\/wp-json\/wp\/v2\/comments?post=1291"}],"version-history":[{"count":2,"href":"https:\/\/nicl.it\/new\/wp-json\/wp\/v2\/posts\/1291\/revisions"}],"predecessor-version":[{"id":1301,"href":"https:\/\/nicl.it\/new\/wp-json\/wp\/v2\/posts\/1291\/revisions\/1301"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/nicl.it\/new\/wp-json\/wp\/v2\/media\/1292"}],"wp:attachment":[{"href":"https:\/\/nicl.it\/new\/wp-json\/wp\/v2\/media?parent=1291"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/nicl.it\/new\/wp-json\/wp\/v2\/categories?post=1291"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/nicl.it\/new\/wp-json\/wp\/v2\/tags?post=1291"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
