| Résumé : |
In the second part of this work, silane-pretreated epoxy coatings on aluminum substrate are theoretically studied by molecular dynamics simulation. The results show that (3-glycidoxypropyl)-trimethoxysilane (GPTMS) provides improved interaction energy for aluminum and epoxy interface and thus ensures satisfactory adhesion. Water diffuses fastest and slowest across the interface of bis-1,2-(triethoxysilyl)ethane (BTSE)- and GPTMS-pretreated painting systems, respectively, suggesting that BTSE has the worst and GPTMS provides the best capability for constructing a reliable interface among the selected painting systems. The existence of both silane pretreatments improves the resistance of structure relaxation of the epoxy polymer chain to water penetration. |
