Vanessa Cristina Gonçalves dos Santos,João Valdir Tadioto Miranda de Souza,César Ricardo Teixeira Tarley,Josiane Caetano,Douglas C. Dragunski +4 more
TL;DR: In this paper, the authors evaluated the copper ion adsorption capacity of sugarcane bagasse in natura and chemically modified with citric acid and sodium hydroxide.
Journal ArticleDOI
Amylopectin-rich starch plasticized with glycerol for polymer electrolyte application
Rozely F.M.S. Marcondes,Páblia S. D'Agostini,Jaqueline Campos Lopes Ferreira,Emerson M. Girotto,Agnieszka Pawlicka,Douglas C. Dragunski +5 more
TL;DR: In this paper, the authors described the preparation and characterization of a solid polymer electrolyte based on amylopectin-rich starch plasticized with glycerol, which was characterized through ionic conductivity measurements, scanning electron microscopy, thermal analysis, and spectroscopy in the UV-Vis-NIR region.
Journal ArticleDOI
Nuclear magnetic resonance and conductivity study of starch based polymer electrolytes
TL;DR: In this paper, the effects of the plasticizer on the ionic mobility in these starch-based electrolytes, as measured by NMR spin-lattice relaxation and conductivity, are discussed.
Journal ArticleDOI
Effect of gelatin and casein additions on starch edible biodegradable films for fruit surface coating

TL;DR: Results indicate that the biodegradable film from a polymer blend consisting of natural cassava starch, casein, and gelatin, and using sorbitol as the plasticizer is a promising material for fruit coating.
Journal ArticleDOI
Ionic Conductivity Thermogravimetry Measurements of Starch-Based Polymeric Electrolytes
TL;DR: In this article, the results of starch and starch derivatives-based electrolytes, which were characterized by impedance spectroscopy and thermal analysis, varied from 10−6 to 10−4 S/cm at room temperature, depending on the sample, and increased following Arrhenius model.
