DMA study of thermoplastic starch/montmorillonite nanocomposites
نویسندگان
چکیده
Dynamic mechanical analysis was used to study the viscoelastic behavior of nanocomposites consisting thermoplastic corn starch plasticized with glycerol and/or urea and addition 2 or 5 wt. % montmorillonite-type nanofiller. Motional heterogeneity studied materials inferred from temperature dependences damping factor. Relaxation processes in composites only one plasticizer proceeded a similar manner same range for both nanofiller concentrations, contrast composite plasticizers, which these were detected at temperatures more than 10 °C shift.

Development and Characterization of Amorphous Thermoplastic Matrix Graphene Nanocomposites
The aim of the present work is the development of amorphous thermoplastic matrix nanocomposites based on graphite nanoparticles. Different types of graphite were used, including unmodified graphite, graphene nanoplatelets and graphite intercalation compounds. Graphite intercalation compounds were subjected to thermal treatment to attain exfoliation of the nanofiller. The exfoliation process was...
متن کاملWater-Assisted Production of Thermoplastic Nanocomposites: A Review
Water-assisted, or more generally liquid-mediated, melt compounding of nanocomposites is basically a combination of solution-assisted and traditional melt mixing methods. It is an emerging technique to overcome several disadvantages of the above two. Water or aqueous liquids with additives, do not work merely as temporary carrier materials of suitable nanofillers. During batchwise and continuou...

Processing, Morphological, Thermal and Absorption Behavior of PLA/Thermoplastic Starch/Montmorillonite Nanocomposites
Thermoplastic starch, polylactic acid glycerol and maleic anhydride (MA) were compounded with natural montmorillonite (MMT) through a twin screw extruder to investigate the effects of different loading of MMT on structure, thermal and absorption behavior of the nanocomposites. X-ray diffraction analysis (XRD) showed that sample with MMT loading 4phr exhibited exfoliated structure while sample t...
