Rheological and mechanical properties of biodegradable nanocomposites
2018
Polymer nanocomposites have gained huge interest over the last decade. However, traditional thermoplastic nanocomposites do not match the rising concern about environmental issues. Therefore, during the last years, the search for biodegradable polymer nanocomposites is gaining importance. Most of biobased (i.e. based on biodegradable/bioderived polymer matrices) nanocomposites have poly(lactic acid), PLA, as matrix. However, it is of clear interest to take into account also different biobased polymer matrices, such as MaterBi. In this work, we prepared bionanocomposites containing MaterBi or a PLA-based polymer matrix, with two different kinds of nanofillers (organomodified clay and nanosiz…
In-process material characterization at constant extrusion conditions: application to clay/PLA bionanocomposites
2017
The authors developed a prototype modular small-scale single / twin-screw extrusion system, with outputs in the range of grams/hour, coupled to a rheo-optical slit die. This experimental set-up is adequate to measure shear viscosity and normal-stress differences and perform optical measurements
