Abstract During curing of thermosetting resins the technologically relevant properties binders and coatings develop. However, is difficult to monitor due multitude chemical physical processes taking place. Precise prediction specific technological based on molecular very difficult. In this study, potential principal component analysis (PCA) regression (PCR) in Fourier transform infrared (FTIR) ...

This review covers both the history and present state of the kinetics of thermally stimulated reactions in solids. The traditional methodology of kinetic analysis, which is based on ® tting data to reaction models, dates back to the very ® rst isothermal studies. The model ® tting approach suŒers from an inability to determine the reaction model uniquely, and this does not allow reliable mechan...

Non-isothermal crystallization kinetics of polydioxanone (PDO), a polymer with well-established applications as bioabsorbable monofilar suture, was investigated by Avrami, Mo, and isoconversional methodologies. Results showed Avrami exponents appearing in a relatively narrow range (i.e., between 3.76 and 2.77), which suggested a three-dimensional spherulitic growth and instantaneous nucleation ...

Abstract In this work, the effect of functionalized hydroxyapatite (HAp-g-PEG) on thermal degradation behaviour and flammability polyoxymethylene copolymer (POM_C) was investigated. Organic–inorganic hybrid additive, obtained by grafting poly(ethylene glycol) HAp surface using 1,6-hexamethylene diisocyanate as a linker, has been incorporated into POM matrix through an extrusion process. TG anal...

The thermodynamics and kinetics of the structural phase transition from monoclinic VO2 (M) to rutile (R) vice versa were studied for particulate materials obtained by bead milling powder. Using wet milling, we decreased particle size powder ∼1 μm 129 nm. With progressive switching enthalpy 47 J g−1 29 due a loss crystallinity. using Friedman's differential isoconversional method. activation ene...

In this paper the feasibility of NbAl3/Al2O3 nanocomposite formation through mechanochemical reaction between Al and Nb2O5 and the effect of mechanical activation on the kinetic and reaction mechanism were investigated. Structural and phase evolution during mechanical alloying were studied by employing transmission electron microscopy (TEM)...
