A study of epoxy composites for high thermal conductivty applications
Moradi, Sasan (Universitat Politècnica de Catalunya, 2021-07-08)
Doctoral thesis
Open AccessNowadays. both electronic and microelectronic circuits have great relevance and wide application in our daily lives and are increasingly being used with higher powers and frequencies. One of the main problems faced by their ... -
Achieving high thermal conductivity in epoxy composites: Effect of boron nitride particle size and matrix-filler interface
Moradi, Sasan; Calventus Solé, Yolanda; Román Concha, Frida Rosario; Hutchinson, John M. (Multidisciplinary Digital Publishing Institute (MDPI), 2019-07-06)
Article
Open AccessFor the thermal management of high watt density circuit layers, it is common to use a filled epoxy system to provide an electrically insulating but thermally conducting bond to a metal substrate. An epoxy-thiol system ... -
Densification: A route towards enhanced thermal conductivity of epoxy composites
Moradi, Sasan; Román Concha, Frida Rosario; Calventus Solé, Yolanda; Hutchinson, John M. (Multidisciplinary Digital Publishing Institute (MDPI), 2021-01)
Article
Open AccessWhen an amorphous polymer is cooled under pressure from above its glass transition temperature to room temperature, and then the pressure is released, this results in a densified state of the glass. This procedure applied ... -
Epoxy composites filled with boron nitride: cure kinetics and the effect of particle shape on the thermal conductivity
Moradi, Sasan; Calventus Solé, Yolanda; Román Concha, Frida Rosario; Hutchinson, John M. (Springer, 2020-05-25)
Article
Open AccessThermally conducting and electrically insulating materials have been prepared by filling an epoxy–thiol system with boron nitride (BN) particles of different shapes (platelets and agglomerates) and sizes (from 2 to 180 ... -
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
Open AccessThis 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 ... -
Stress-relaxing thermosets with easily regulated bond exchange kinetics
Konuray, Ali Osman; Moradi, Sasan; Fernández Francos, Xavier; Serra Albet, Maria Àngels; Ramis Juan, Xavier; Morancho Llena, José María (2022)
Conference lecture
Open AccessWe have carried out stress-relaxation experiments on poly(acrylate) and poly(thiol-ene) based thermosets prepared from in-house synthesized epoxy-acid adducts with acrylate (for the former) and ene functionalities (for the ... -
Thermal conductivity and cure kinetics of epoxy-boron nitride composites: A review
Hutchinson, John M.; Moradi, Sasan (Multidisciplinary Digital Publishing Institute (MDPI), 2020-08-17)
Article
Open AccessEpoxy 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 ... -
Thiol-Ene Networks with Tunable Dynamicity for Covalent Adaptation
Konuray, Ali Osman; Moradi, Sasan; Roig, Adrià; Fernández Francos, Xavier; Ramis Juan, Xavier (American Chemical Society (ACS), 2022-01-01)
Article
Open AccessTo be fully recyclable, covalent adaptable networks must ultimately be able to overcome all topological restrictions and flow. By using a statistically based method, it was shown that the extent of stress relaxation in ...
