Obtaining and characterizing a biodegradable polymer from cassava starch

In this investigation a biodegradable polymer is obtained from cassava starch by processing mixtures of modified starch with glycerin and water as plasticizers, using an open mill and a single screw extruder. The variables to be controlled during extrusion are: temperature profile, torque, and spind...

Las variables a controlar durante la extrusión son: perfil de temperatura, torque, y velocidad de rotación del husillo. Se evalúan características mecánicas y fisicoquímicas mediante ensayos de tensión, análisis térmicos de Calorimetría Diferencial de Barrido (DSC) y Análisis Termogravimétrico (TGA), Análisis Infrarrojo por Transformadas de Fourier (FTIR) y morfología.application/pdfspaUniversidad EAFIThttp://publicaciones.eafit.edu.co/index.php/ingciencia/article/view/457http://publicaciones.eafit.edu.co/index.php/ingciencia/article/view/457Copyright (c) 2006 Gladys Ruiz AvilésAcceso abiertohttp://purl.org/coar/access_right/c_abf2instname:Universidad EAFITreponame:Repositorio Institucional Universidad EAFITIngeniería y Ciencia; Vol 2, No 4 (2006)Obtaining and characterizing a biodegradable polymer from cassava starchObtención y caracterización de un polímero biodegradable a partir del almidón de yucaarticleinfo:eu-repo/semantics/articlepublishedVersioninfo:eu-repo/semantics/publishedVersionArtículohttp://purl.org/coar/version/c_970fb48d4fbd8a85http://purl.org/coar/resource_type/c_6501http://purl.org/coar/resource_type/c_2df8fbb1Biodegradable PolymersCassava StarchPolymer CharacterizationExtrusionPolímeros BiodegradablesAlmidón De YucaCaracterización De PolímerosExtrusiónRuiz Avilés, GladysUniversidad EAFITIngeniería y Ciencia24528ing.cienc.THUMBNAILminaitura-ig_Mesa de trabajo 1.jpgminaitura-ig_Mesa de trabajo 1.jpgimage/jpeg265796https://repository.eafit.edu.co/bitstreams/2e9f4c6f-d52f-495a-a55f-95d2644a6c46/downloadda9b21a5c7e00c7f1127cef8e97035e0MD51ORIGINALdocument (3).pdfdocument (3).pdfTexto completo PDFapplication/pdf267271https://repository.eafit.edu.co/bitstreams/0d6544cb-6a03-4332-86f4-aaa3a1c95b35/download75a823c3d0464b64cee26d1ab1e53fa0MD52articulo.htmlarticulo.htmlTexto completo HTMLtext/html373https://repository.eafit.edu.co/bitstreams/01402c99-2ab0-49a6-9785-51c67bd37e04/downloadc34a51d086803211bc598e78f53d7893MD5310784/14550oai:repository.eafit.edu.co:10784/145502020-03-02 23:26:36.699open.accesshttps://repository.eafit.edu.coRepositorio Institucional Universidad EAFITrepositorio@eafit.edu.co
