Sodium montmorillonite silylation: unexpected effect of the aminosilane chain length.
In this work, the silylation of sodium montmorillonite (Na-MMT) was performed in glycerol using 3-aminopropyltriethoxysilane, N-(2-aminoethyl)-3-aminopropyltrimethoxysilane andExpand
Processing and shelf life issues of selected food packaging materials and structures from renewable resources
Use of polymers from renewable sources for food packaging applications is steadily growing. However, as compared to thermoplastic synthetic polymers, they present problems when processed withExpand
A novel spectroscopic approach to investigate transport processes in polymers: the case of water–epoxy system
Abstract A novel experimental approach, based on in situ FTIR spectroscopy in the transmission mode, has been developed to monitor sorption–desorption behaviour of small molecules in polymer films.Expand
Flexible packaging structures for high pressure treatments
Abstract This paper reviews the possible effects determined on polymeric food packaging films by the simultaneous application of pressure (P) and temperature (T) in high pressure pasteurization andExpand
Assessing the suitability of polylactic acid flexible films for high pressure pasteurization and sterilization of packaged foodstuff
Abstract Effects of high pressure (HP) pasteurization and sterilization processes on the properties of commercial biodegradable polylactic acid (PLA), used as packaging material, have beenExpand
α-Tocopherol release from active polymer films loaded with functionalized SBA-15 mesoporous silica
Abstract The aim of the present work is the study of the migration from active LDPE polymer films of α-tocopherol adsorbed onto purely siliceous and amino-functionalized SBA-15 mesoporous silica. InExpand
Synthesis and characterization of clay-nanocomposite solvent-based polyurethane adhesives
Abstract In this work nanocomposite adhesives obtained using an organically modified montmorillonite (OMM) in a polyurethane matrix were studied. An amount of organoclay ranging from 3% up to 18% byExpand
Combining gravimetric and vibrational spectroscopy measurements to quantify first- and second-shell hydration layers in polyimides with different molecular architectures.
In-situ Fourier transform infrared (FTIR) measurements have been carried out at different relative pressures of water vapor to study the H(2)O diffusion in three polyimides differing in theirExpand
Thermodynamics of water sorption in poly(ɛ-caprolactone): A comparative analysis of lattice fluid models including hydrogen bond contributions
Abstract Thermodynamics of water sorption in poly(ɛ-caprolactone) (PCL) has been interpreted by using three models based on compressible lattice fluid theories, addressing the issue of self- andExpand
THE EFFECT OF FILM THICKNESS ON OXYGEN SORPTION AND TRANSPORT IN DRY AND WATER-SATURATED KAPTON POLYIMIDE
Abstract Sorption and transport of oxygen in dry and water saturated Kapton® polyimide films of different thickness were investigated at 25°C with pure oxygen using: (i) a manometric permeationExpand
