Fonseca, E.; Demetrio da Silva, V.; Klitzke, J. S.; Schrekker, H. S.; Amico, S. C. published the artcile< Imidazolium ionic liquids as fracture toughening agents in DGEBA-TETA epoxy resin>, Formula: C6H9ClN2O2, the main research area is epoxy resin imidazolium ionic liquid mech thermal property.
Although epoxy resins are used in a broad variety of applications due to their good mech. and thermal properties, their low fracture toughness is a limitation, exhibiting brittle behavior. This study explored the potential use of imidazolium ionic liquids (IL) as toughening agents for epoxy resin based on diglycidyl ether of bisphenol A (DGEBA) with triethylenetetramine (TETA) as curing agent. Fracture toughness was evaluated for DGEBA-TETA epoxy resins with eleven imidazolium IL and the best results were found for the IL with the chloride anion and the shortest N-alkyl side chain, C4MImCl. The use of 1.0 phr of C4MImCl lead to the reduction of the crosslink d. of the post-cured resin, resulting in the increase of 25.5% in stress intensity factor and 8.2% in tensile strength with no significant loss in other mech. properties.
Polymer Testing published new progress about Bending strength. 700370-07-6 belongs to class imidazoles-derivatives, and the molecular formula is C6H9ClN2O2, Formula: C6H9ClN2O2.
