Preparation and Characterization of Vinyl Ester Monomer-Toughened Epoxy-Clay Hybrid Nanocomposites: Thermal and Morphological Properties

摘要

An intercross-linked network of vinyl ester monomer (VEM)-toughened epoxy-clay hybrid nanocomposites was developed and characterized using analytical methods. Cyclohexyl-1,1′-bis[4-(γ-2-methylphenoxy)-α-hydroxypropylacrylate]-based VEM was synthesized from 1,1-bis(3-methyl-4-glycidyloxyphenyl) cyclohexane and acrylic acid. The VEM was subsequently blended with diglycidyl ether of bisphenol-A (DGEBA) resin cast and cured with 4,4′-diaminodiphenylmethane (DDM). VEM-toughened epoxy matrices were reinforced with organophilic montmorillonite (OMMT) clay yielding hybrid epoxy nanocomposites. Data obtained from thermal characterization indicate that the introduction of VEM into epoxy resin improves thermal properties. The morphological behavior of the nanocomposite was analyzed by X-ray diffraction (XRD) analysis and transmission electron microscopy (TEM).View full textDownload full textKeywordsEpoxy resin, Flame retardancy, Morphology, Nanocomposites, Vinyl ester monomerRelated var addthis_config = { ui_cobrand: "Taylor & Francis Online", services_compact: "citeulike,netvibes,twitter,technorati,delicious,linkedin,facebook,stumbleupon,digg,google,more", pubid: "ra-4dff56cd6bb1830b" }; Add to shortlist Link Permalink http://dx.doi.org/10.1080/1023666X.2012.696399
