Carbon-based polymer nanocomposites for 3D-printing
… parts obtained by fused deposition modeling (FDM). The attention is focused on carbon-based nanomaterials incorporated into an acrylonitrile–butadiene–styrene (ABS) polymer by a solvent-free process. ABS-based nanocomposites were prepared by incorporating different kinds and amounts of …

Environmentally friendly hybrid coatings for corrosion protection: silane based pre-treatments and nanostructured waterborne coatings
… of metals pre-treatments and organic coatings (a complete protection system at all) designed from the nanoscale. The final aim is to develop protection systems with improved corrosion protection properties and a low environmental impact. In particular, multifunctional silane hybrid …

Cryomilling and Spark Plasma Sintering of 2024 Aluminium Alloy
… specific weight, which make them highly interesting for structural applications. Mechanical properties are lower than those of steels, so the possibility to obtain an increase by means of the structural refining (either nano- or ultra-fine grained structure) would extend their applications in …

Synthesis and Optical Characterization of Boron based Nanostructured Materials
… formed by electron-deficient, multi-center bonding, which results in a broad range of physical and chemical properties. When compared to other elemental nanomaterials, boron-based nanomaterials exhibit uncommon behaviours due to their distinct bonding characteristics. Due to their reactive …

Preparation and properties of micro- and nanocomposites based on high density polyethylene
… based on polyethylene (PE) produced by melt mixing. To achieve these objectives, different fillers were considered: micrometric copper particles, nanometric carbon blacks (CBs) and multiwalled carbon nanotubes (MWCNTs). In the first part of this dissertation, the fracture behaviour of PE-CB …

Micro- and Nanostructured Polymeric Materials for art protection and Restoration
… within commercially available art preserving polymers may allow the improvement of their mechanical deficiencies, without impairing their physical and chemical properties. Cellulose microcrystals (CMC) and nanocrystals (CNC) were selected as natural reinforcing fillers for a commercial …
