Journal ArticleDOI
Sodium montmorillonite silylation: Unexpected effect of the aminosilane chain length
Filomena Piscitelli,Paola Posocco,Radovan Toth,Maurizio Fermeglia,Sabrina Pricl,Giuseppe Mensitieri,Marino Lavorgna +6 more
TL;DR: It was found that the degree of silylation of Na-MMT increases with increasing the length of the aminosilane organic moieties, the overall aminoilane concentration, and temperature, and the same beneficial effects were observed on the silicate d-spacing.
Journal ArticleDOI
Computer simulation of polypropylene/organoclay nanocomposites: characterization of atomic scale structure and prediction of binding energy
Radovan Toth,Radovan Toth,A. Coslanich,Marco Ferrone,Maurizio Fermeglia,Sabrina Pricl,Stanislav Miertus,Emo Chiellini +7 more
TL;DR: In this article, molecular simulation techniques are used to explore and characterize the atomic scale structure, and to predict binding energies and basal spacing of polymer/clay nanocomposites based on polypropylene (PP) and maleated polypropylon (PPMA), montmorillonite (MMT), and different alkylammonium ions (quats) as surfactants.

Multiscale Computer Simulation Studies of Water-Based Montmorillonite/Poly(ethylene oxide) Nanocomposites
Radovan Toth,DJ Voorn,Jan-Willem Handgraaf,Johannes G. E. M. Fraaije,Maurizio Fermeglia,Sabrina Pricl,Paola Posocco +6 more
TL;DR: In this article, a multiscale computational approach is presented to probe the behavior of polymer/clay nanocomposites based on poly(ethylene oxide) (PEO)/montmorillonite (MMT) as obtained from water intercalation.
Journal ArticleDOI
Structure and Energetics of Biocompatible Polymer Nanocomposite Systems: A Molecular Dynamics Study
TL;DR: The results of theoretical computations show that nanoconfined conformations of smaller NSAIDs are more affected by the presence of water molecules in the clay gallery with respect to their larger counterparts, and the best intercalation results in a solvated environment could be obtained with PVA in the case of less polar drugs, while PHB could be the polymer of choice in the cases of highly polar NSAIDs.
