Within the conservation of artworks materials, this chapter describes innovative strategies based on clay nanoparticles that are promising for protective coating, surface cleaning, and consolidation. We present the preparation of polymer/montmorillonite nanocomposites, which are revealed as efficient protective coatings for highly porous stones ...

Fluorescent labeling and tracking of nanoclay
Nanoscale, 2013We report a methodology developed to detect and track stable fluorescent-labeled nanoclay, in polymer-clay nanocomposite films, and in a contact solvent after migration testing. Fluorescein-5-maleimide (fluorescein) or tetramethylrhodamine-5-maleimide (rhodamine) was covalently bonded to organically modified montmorillonite (o-MMT).

Extruded starch–nanoclay nanocomposites: Effects of glycerol and nanoclay concentration
Polymer Engineering & Science, 2007Abstract Wheat starch‐Cloisite Na+ nanoclay composites containing different glycerol and nanoclay concentrations were extruded using a twin‐screw extruder. X‐ray diffraction and transmission electron microscopy were used to determine the extent of nanoclay dispersion and thermogravimetric analysis was used to characterize thermal ...

Nanoclays as Asphalt-Binder Modifiers
2013Among the solutions to reduce failures of road pavements, polymer-modified asphalts (PMAs) represent the most effective one and have been adopted worldwide in the last decades. PMAs are blends of asphalt and a polymer, where the latter is swollen by the bituminous material, thus forming a network whose structure closely resembles that of gels ...

Optimization Effect of Micro Hardness by Nanoclay Clusters in Nanoclay/Epoxy Composites
Journal of Thermoplastic Composite Materials, 2009Nanoclay/epoxy composites have been investigated extensively on their mechanical and thermal properties over the last decade. Researches have been mainly focused on the control of manufacturing a fully exfoliated inter-planar structure of nanoclay platelets inside epoxy resin in order to achieve the maximum mechanical strength of the composites ...

Nanoclay-reinforced polyurethane
2015Polyurethane-layered silicate nanocomposites with different layered silicates, montmorillonite (MMT) and attapulgite (ATT), were investigated to gain fundamental understanding of the role of nanofillers, the chemistry of the modifiers, and the physics of polymer nanocomposites.
