چکیده
Abstract The paper presents the results of research on influence used plasticizing system structural and thermal properties thermoplastic starch (TPS). granulate was obtained by extrusion native in presence a using twin-screw extruder. Glycerol urea were as plasticizers various proportions. In order to evaluate effectiveness plasticization process, changes its chemical structure analyzed infrared spectroscopy (FTIR), gel permeation chromatography (GPC) X-ray diffraction (XRD). TPS stability determined thermogravimetric analysis (TGA). An improvement efficiency process has been found for urea-containing compared composition plasticized only with glycerol. addition, XRD confirms beneficial effect inhibition retrogradation process.

The paper is focusses on the study of the thermal and mechanical behaviour of reinforced agro-materials. Various formulations based on plasticized starch matrix have been carried out, varying matrix formulation, filler content, fibres length and nature. Cellulose and lignocellulose fibres, which show unequal surface tensions, have been tested. After extrusion and injection moulding, the propert...
متن کاملMechanical, thermal and structural properties of rice starch films reinforced with rice starch nanocrystals
A rice starch based film, reinforced with starch nanocrystals (prepared by submitting native granules of rice starch to acid hydrolysis at 40 oC) was prepared by casting film-solution on leveled trays. The influence of the content of starch nanocrystals (5 to 30%) on the mechanical, thermal and structural properties of rice starch films was investigated. The rice starch films showed an increase...
