Preparation of a new generation porous thermal insulation mass using functional nanomaterials
In this work silica precursor is graft on nanomaterials via a free-radical reaction. The modified nanomaterials have an - OEt functional group which allows us to intercalate the polymer between the layers of expandable graphite [...]
Effect of γ-ray irradiated MWCNTs on electrical conductivity of a PET/graphite composite for a bipolar plate application
The effects of a compounding method and γ-ray treated multiwall carbon nanotubes (MWCNTs) on the electrical conductivity of graphite/PET composites were investigated. We found that dispersion of MWCNTs in the PET phase plays a critical [...]
Dielectric performance of Polymer Nanocomposites Synthesized by Atmospheric-pressure Plasma-treated Silica Nanoparticles
The incorporation of nanoparticles can effectively enhance the dielectric performance of polymers. However, the organic-inorganic incompatibility prevents the nanocomposites from obtaining the desired properties. To overcome this issue, coupling agents have been used to coat [...]
Elastomer composites containing layered fillers and hydroxyapatities
Traditionally, as a filler of rubber carbon black is used. It is an active filler able to reinforce and improve the properties of finished rubber products. For ecological and economic reasons the research activity is [...]
Assessing the Antimicrobial Activity of Silver Nanoparticles Leached from Medical Devices
This work focuses on characterization the leachables released from substrates, e.g. medical devices, containing silver nanoparticles. Furthermore, antimicrobial experiments were conducted to determine how the structure of a silver nanoparticle impact antimicrobial activity. Proper characterization [...]
Investigation of Silica Nanoparticles Accumulated on the Surface of Polymer Nanocomposites Exposed to UV Radiation Using ICP-OES
Silica nanoparticles are being utilized to enhance the mechanical performance of polymeric materials used in the automotive and construction industries. However, cumulative effects of UV radiation will degrade the polymeric molecules, resulting in a potential [...]
FreeNano – Test Methods for Release of Pigment-Nanoparticles Into the Environment at the End of Life Cycle
Several coatings with and without nanoscaled additives and pigments were exposed to artificial aging and weathering, before they experienced a mechanical treatment by sanding with process parameters similar to professional sanding condition. The miniature sanding [...]
