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 ...

Recyclable polyurethane/nanoclay films
Polymer Composites, 2019A series of polyurethane (PU)/clay nanocomposite films was prepared by adding natural bentonite Cloisite® Na+ powders to waterborne polyurethane dispersions (PUDs) followed by a slow water evaporation; the nanoclay content in the films varied from 0 to 5 wt%.

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.

Nanoclay and Modified Nanoclay as Sorbents for Anionic, Cationic and Nonionic Dyes
Textile Research Journal, 2005The nanoclay, montmorillonite, and some modified nanoclays were used as sorbents for nonionic, anionic and cationic dyes. From the sorption differences among the different dye and clay structures, both chemical and morphological, the sorption forces that played important roles were identified. The nanoclay could easily have a sorption capacity of more

Nanoclay migration from food packaging materials
Food Additives & Contaminants: Part A, 2016A recent trend is to use nanocomposites materials for food-packaging applications. Different kinds of nanoparticles are incorporated into the polymers to improve their characteristics, and, among them, nanoclay is used to improve their barrier properties to gases. In this work, the results of migration studies with different food simulants (ethanol 10%

Characterisation of nanoclay dispersion in resin transfer moulded glass/nanoclay/epoxy composites
Plastics, Rubber and Composites, 2004A novel approach for characterisation of nanoclay dispersion in polymeric composites using electron microprobe analysis (EMPA) is presented. Dispersion analysis was performed on three sets of centre-gated discs fabricated by resin transfer moulding.

Compatibilization Mechanism of Nanoclay in Immiscible PS/PMMA Blend Using Unmodified Nanoclay
Polymer-Plastics Technology and Engineering, 2013Organically modified nanoclays have been reported to play the role of a compatibilizer for immiscible polymer blends. However, the mechanism of compatibilization by nanoclay has been reported differently. In this work, we investigated the exact mechanism of compatibilization of nanoclay in immiscible polystyrene (PS)/poly(methyl methacrylate) (PMMA ...
