Orientation and exfoliation of clay nanoparticles in the spinning of a nanobiocomposite sample
2016
Polymer nanobiocomposites represent a new group of materials filled with inert nanosized particles that show very interesting properties with respect to the matrix and the same biodegradability of the matrix. In this work we have studied the effect of the elongational flow on the morphology and dynamic-mechanical properties of a new nanobiocomposite made by a matrix of biodegradable PLA and a filler of organomodified montmorillonite.

New experimental tools for the characterization of highly overconsolidated clayey materials in unsaturated conditions
2010
This chapter presents some of the experimental facilities that have recently been developed at the EPFL Soil Mechanics Group. Three apparatuses operating in non-isothermal conditions are described in detail: a sorption bench for determining water retention curves, an oedometric cell for analyzing volumetric responses under high vertical loads, and a triaxial cell designed for extreme loading conditions.
The role of the matrix-filler affinity on morphology and properties of polyethylene/clay and polyethylene/ compatibilizer/clay nanocomposites drawn f…
2009
In this work the structural variations and mechanical performance of polyethylene/clay nanocomposite drawn fibres, also in the presence ofcompatibilizer, such as a commercial maleic anhydride grafted polyethylene, PEgMA, was studied. In the isotropic state both systems show intercalated morphology.After spinning and cold drawing, by adding the nanoparticles, the tensile strength as a function of the draw ratio increases and this rise is more pronounced for the filled compatibilized system. The reduction of the elongation at break, on the contrary, is about the same for all the examined samples. The orientation of the macromolecules, evaluated by measurements of the birefringence and calorim…

Earth Bricks with Halloysite Nanoclay: Research and Experimentation for the Sustainability of Materials
2021
The paper illustrates the experimentation activities on rammed earth and nanotechnologies conducted by the authors. The experimental research was carried out with the aim of improving the performance of rammed earth bricks with clay nanotubes, creating a ‘new material’ with reduced embodied energy and low CO2 emissions into the atmosphere. Specifically, the analysed performances are related to the compressive strength that expand their area of use as a building material.
