Article
Open AccessThree different protocols for the preparation of polymer layered silicate nanocomposites based upon a tri-functional epoxy resin, triglycidyl para-amino phenol (TGAP), have been compared in respect of the cure kinetics, ... -
Highly exfoliated nanostructure in trifunctional epoxy/clay nanocomposites using boron trifluoride as initiator
Hutchinson, John M.; Shiravand, Fatemeh; Calventus Solé, Yolanda; Fernández Francos, Xavier; Ramis Juan, Xavier (Wiley, 2014-03-15)
Article
Open AccessEpoxy/clay nanocomposites based upon a trifunctional epoxy resin, triglycidyl p-amino phenol (TGAP), have been prepared by intercalating an initiator of cationic homopolymerization, a boron trifluoride monoethylamine ... -
Influence of the isothermal cure temperature on the nanostructure and thermal properties of an epoxy layered silicate nanocomposite
Shiravand, Fatemeh; Hutchinson, John M.; Calventus Solé, Yolanda (2013-03-08)
Article
Restricted access - publisher's policyThe cure kinetics of triglycidyl p-amino phenol (TGAP) epoxy resin with a diamine (4,4-diamino diphenyl sulphone [DDS]), reinforced with montmorillonite (MMT), has been studied by differential scanning calorimetry. The ... -
Intra- and extra-gallery reactions in tri-functional epoxy polymer layered silicate nanocomposites
Hutchinson, John M.; Shiravand, Fatemeh; Calventus Solé, Yolanda (2012-09-05)
Article
Restricted access - publisher's policyAchieving a high degree of exfoliation in epoxy-based polymer layered silicate (PLS) nanocomposites is crucial to their successful industrial application, but has hitherto proved elusive. In this work, a system is presented ... -
Isothermal and non-isothermal cure of a tri-functional epoxy resin (TGAP): a stochastic TMDSC study
Hutchinson, John M.; Shiravand, Fatemeh; Calventus Solé, Yolanda; Fraga Rivas, Iria (2012-02-10)
Article
Restricted access - publisher's policyThe isothermal cure of a highly reactive tri-functional epoxy resin, tri-glycidyl para-amino phenol (TGAP), with diamino diphenyl sulphone (DDS), at two different cure temperatures Tc has been studied by both conventional ... -
Non-isothermal cure and exfoliation of tri-functional epoxy-clay nanocomposites
Shiravand, Fatemeh; Hutchinson, John M.; Calventus Solé, Yolanda (Budapest University of Technology and Economics, 2015)
Article
Open AccessThe non-isothermal cure kinetics of polymer silicate layered nanocomposites based on a tri-functional epoxy resin has been investigated by differential scanning calorimetry. From an analysis of the kinetics as a function ... -
Study of the exfoliation process in epoxy-clay nanocomposites
Shiravand, Fatemeh (Universitat Politècnica de Catalunya, 2014-06-03)
Doctoral thesis
Open AccessCured epoxy resins are highly cross-linked polymers which are increasingly important in high performance engineering field due to the stiffness, high strength, heat resistance and solvent resistance. However one major ... -
Thermal analysis of polymer layered silicate nanocomposites. Identification of nanostructure development by DSC
Shiravand, Fatemeh; Fraga Rivas, Iria; Cortés Izquierdo, María Pilar; Calventus Solé, Yolanda; Hutchinson, John M. (2014-11-01)
Article
Restricted access - publisher's policyIt has been shown, for three different polymer layered silicate (PLS) nanocomposite systems, how differential scanning calorimetry (DSC) can identify the different reactions of homopolymerisation and of crosslinking that ...
