Polymer layered silicate (PLS) nanocomposites have been prepared with diglycidyl ether of bisphenol-A (DGEBA) epoxy resin as the matrix and organically modified montmorillonite (MMT) as the clay nanofiller. Resin-clay mixtures with different clay con

Publikováno v: Macromolecular Chemistry and Physics. 211:57-65

The processes of vitrification and devitrification that occur during the non-isothermal cure of a cross-linking system are studied in terms of their dependence on frequency. Experimental results are obtained by TOPEM, a new multi-frequency temperatur

Publikováno v: Journal of Thermal Analysis and Calorimetry. 86:235-241

The thermal degradation of an epoxy system consisting of a diglycidyl ether of bisphenol A (DGEBA, n=0) and m-xylylenediamine (m-XDA) was studied by both thermogravimetric analysis (TG) and dielectric analysis (DEA). It has been checked a deviation o

The glassy state of matter is common to all types of materials, be they metallic, inorganic or polymeric, for example. The transformation from an equilibrium liquid state to a nonequilibrium glassy state is usually achieved by cooling at a rate suffi
