Article
Accés obertThe physical aging behaviour of two epoxy-thiol shape memory polymers has been studied: diglycidyl ether of bisphenol-A cross-linked with pentaerythritol tetrakis, denoted 4-thiol, with a calorimetric glass transition ... -
Remarkable Thermal Conductivity of Epoxy Composites Filled with Boron Nitride and Cured under Pressure
Moradi, Sasan; Román Concha, Frida Rosario; Calventus Solé, Yolanda; Hutchinson, John M. (Multidisciplinary Digital Publishing Institute (MDPI), 2021-03)
Article
Accés obertThis work demonstrates that the application of even moderate pressures during cure can result in a remarkable enhancement of the thermal conductivity of composites of epoxy and boron nitride (BN). Two systems have been ... -

The application of thermal analysis to the study of epoxy–clay nanocomposites
Hutchinson, John M. (Springer, 2016-08)
Article
Accés obertThe development of polymer layered silicate (PLS) nanocomposites goes back over 20 years now, and yet they still have not achieved their full potential. A principal reason for this is the difficulty of obtaining a truly ... -
The surface modification of boron nitride particles
Daneshmehr, Shahla; Román Concha, Frida Rosario; Hutchinson, John M. (Springer, 2019-01-01)
Article
Accés obertThe use of coupling agents to enhance the thermal conductivity of composites of epoxy and boron nitride (BN) has been investigated. Two types of BN particles, lightly aggregated platelets with an average size of 6 µm and ... -

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
Accés restringit per política de l'editorialIt 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 ... -
Thermal and oxidative degradation of epoxy based layered silicate nanocomposites
Román Concha, Frida Rosario; Calventus Solé, Yolanda; Hutchinson, John M.; Montserrat Ribas, Salvador (2009)
Comunicació de congrés
Accés restringit per política de l'editorialThe thermal oxidative degradation of several polymer/clay nanocomposites with a range of clay contents has been determined. It is found that the dispersion of the clay in the resin matrix plays a crucial role in the ... -

Hutchinson, John M.; Moradi, Sasan (Multidisciplinary Digital Publishing Institute (MDPI), 2020-08-17)
Article
Accés obertEpoxy resin composites filled with thermally conductive but electrically insulating particles play an important role in the thermal management of modern electronic devices. Although many types of particles are used for ... -
TOPEM, a new temperature modulated DSC technique - Application to the glass transition of polymers
Fraga Rivas, Iria; Montserrat Ribas, Salvador; Hutchinson, John M. (2007-01-30)
Article
Accés restringit per política de l'editorialTOPEM is a new temperature modulated DSC technique, introduced by Mettler-Toledo in late 2005, in which stochastic temperature modulations are superimposed on the underlying rate of a conventional DSC scan. These modulations ... -
