Influência do tratamento físico da fibra de coco nas propriedades mecânicas do biocompósito com matriz de poliéster insaturada
(Universidade Estadual Paulista (UNESP), 2018-07-30)
Maior conscientização em relação as questões ambientais, atrelada a escassez de recursos, problemas ambientais globais e a políticas ambientais cada vez mais fortes influenciaram indústrias e pesquisadores a apreciar, ...
Properties and processing relationship of polyhydroxybutyrate and cellulose biocomposites
The aim of this work was the development of totally biodegradable composites for using as packaging in food and agriculture industry. Optimum conditions to obtain bilayer composites from polyhydroxybutyrate (PHB) and ...
Morphology and properties of neutralized chitosan-cellulose nanocrystals biocomposite films
Chitosan/cellulose nanocrystals (CH-CN) films were obtained by casting of dispersions, and treated with NaOH for neutralization proposes. The composition of films was varied from 1 to 10 wt.% of CN. Changes in the morphology ...
A short review on novel biocomposites based on plant oil precursors
(Pergamon-elsevier Science Ltd, 2013-03-13)
The last two decades have witnessed an exponential growth in the interest for using bioderived products in the polymer field, which is driven by the need to replace petroleum based materials and reduce the fuel consumption ...
Absorption of Siderite Within a Chemically Modified Poly(lactic acid) Based Composite Material for Agricultural Applications
(Springer/Plenum Publishers, 2018-05)
Iron is an essential micronutrient for higher plants. Although abundant in most soils, Fe3+ is not available for plant uptake, because of its poor solubility. Ferrous sulfate is a fertilizer used for crops but, Fe2+ is ...
Progress in bacterial cellulose matrices for biotechnological applications
Bacterial cellulose (BC) is an extracellular polymer produced by many microorganisms. The Komagataeibacter genus is the best producer using semi-synthetic media and agricultural wastes. The main advantages of BC are the ...
Removal of Phenol by Immobilization of Trametes versicolor in Silica–Alginate–Fungus Biocomposites and Loofa Sponge
(Wiley VCH Verlag, 2015-12-10)
White-rot fungi have potential in organic pollutant degradation. Immobilization of microorganisms has been successfully used for bioremediation. In this work, 25 isolates of Argentinean white-rot fungi were tested for their ...
Biodegradable jute cloth reinforced thermoplastic copolyester composites: Fracture and failure behaviour
(Maney Publishing, 2006-07)
Jute cloth reinforced, fully biodegradable thermoplastic composites were produced by the film stacking technique, with a semicrystalline copolyester (Ecoflex) as the matrix material. The jute cloth content varied between ...
Influence of the layered silicate type on the structure, morphology and properties of cellulose acetate nanocomposites
