Thermal Degradation Studies of Poly(2-ethyl hexyl acrylate) in the Presence of Nematic Liquid Crystals
Abstract
Le comportement de dégradation thermique du poly(2-éthyl hexyl hcrylate) (Poly(2-EHA)), mélangé à un mélange nématique de cristaux liquides (LC) disponible dans le commerce, a été étudié par analyse gravimétrique thermique (TGA). Différentes vitesses de chauffage, allant de 5 à 200 °C/min, ont été appliquées sous atmosphère inerte. Sur la base des résultats de l'ATG, les énergies d'activation (Eα) à différents taux de conversion (α) ont été déterminées à l'aide de trois méthodes d'isoconversion intégrale : Flynn-Wall-Ozawa (FWO), Tang et Kissinger-Akahira-Sunose (KAS). On constate que l'évolution globale de ces énergies d'activation est la même pour les trois modèles. Le coefficient de détermination R2 a présenté des valeurs généralement supérieures à 0,97. En utilisant ces modèles, la valeur Eα pour la LC reste constante à 64 kJ/mol pour tous les taux de conversions. Pour le polymère Poly(2-EHA), en appliquant les modèles Tang et FWO, l'énergie d'activation présente une variation allant de 80 kJ/mol, pour la conversion α = 0,1, à 170 kJ/mol, pour α = 0,9. Pour le troisième modèle (KAS), cette énergie varie entre 80 et 220 kJ/mol dans la même gamme de α. ; The thermal degradation behavior of Poly(2-ethyl hexyl hcrylate) (Poly(2-EHA)), blended with a commercially available nematic liquid crystal (LC) mixture, was investigated by thermal gravimetric analysis (TGA). Different heating rates, ranging from 5 to 200 °C/min, were applied under an inert atmosphere. Based on the TGA results, activation energies (Eα) at different conversion rates (α) were determined using three integral isoconversion methods: Flynn-Wall-Ozawa (FWO), Tang, and Kissinger-Akahira-Sunose (KAS). It can be noticed that the global evolution of these activation energies was the same for the three models. The coefficient of determination R2 presented values generally higher than 0.97. Using these models, the Eα value for the LC remains constant at 64 kJ/mol for all conversions rates. For the polymer Poly(2-EHA), applying the Tang and FWO models, ...
