In this study, a novel polymerizable ionic liquid monomer (ILM) based on a bisimidazolium salt was first synthesized in order to substitute bisphenol A diglycidyl ether (DGEBA) as a starting material, avoiding the use of highly toxic and carcinogenic bisphenol A and epichlorohydrin products. From such a new epoxy monomer, an epoxy network was prepared from the copolymerization between the bisimidazolium salt and isophorone diamine (IPD). Subsequently, the properties of this novel ionic liquid based polymer network have been investigated in terms of polyaddition reaction kinetics as well as the architectureproperties, i.e., thermal stability, surface properties, and the mechanical performances. In addition, for the first time, molecular dynamics simulations were combined with experimental measurements in order to confirm the experimental data as well to be able to predict the physical behaviors from their architecture, molecular scale structuration, and thermomechanical properties of the resulting network. Finally, the substitution of DGEBA by this ILM led to a thermosetting polymer with high thermal stability (up to 450 °C), hydrophobic behavior (21 mJ m −2 ), and promising mechanical performances (1.7 GPa) including a shape memory behavior.

In this paper, different types of polyurethane foams (PUR) having various chemical compositions have been produced with a specific density to monitor the microstructure as much as possible. The foam may have a preferential orientation in the cell structure. The cellular polyurethane tends to have stubborn, typical cellular systems with strong overlap reversibility. Free expansion under atmospheric pressure enables formulas to grow until they are refined. Moreover, the physicochemical characterization of the developed foams was carried out. They later are described by apparent density, Shore hardness, Raman spectroscopy analysis, X-Ray diffraction analysis, FTIR, TGA, DSC, and compression tests. The detailed structural characterization was used by scanning electron microscope (SEM) and an optical microscope (MO) to visualize the alveolar polymer’s semi-opened cells, highlighting the opened-cell morphology and chemical irregularities. Polyurethane foams with different structural variables have a spectrum characterization that influences the phase separation and topography of polyurethane foam areas because their bonding capability with hydrogen depends on chain extender nature. These studies may aid in shock absorption production; a methodology of elaboration and characterization of filled polyurethane foams is proposed.

In this work, two polyhedral oligomeric silsesquioxane-supported imidazolium ionic liquid have been successfully synthesized and used as organic-inorganic hybrid nano-objects in order to design nanostructured epoxy-amine networks. In fact, two partially condensed POSS have been covalently grafted with an ionic liquid-functionalized silane. The thermal properties of the ionic liquid (IL)-modified POSS have highlighted a significant enhancement of the thermal stability (400 vs 300 °C).Then, these hybrid organic-inorganic nano-objects (5 wt. %) have been incorporated into a conventional epoxy prepolymer (diglycidyl ether of bisphenol A) which was copolymerized with the isophorone diamine in order to prepare nanostructured networks. Thus, an excellent dispersion of the IL-functionalized POSS was obtained in the thermosetting networks, characterized by the formation of spherical or ellipsoïdal inorganic-rich nanoparticles with nanoscale sizes (10 to 80 nm).i.e. high thermal stability, low saturation vapor pressure, low flammability, dispersant capabilities, and high ionic
