    • A study of epoxy composites for high thermal conductivty applications 

      Moradi, Sasan (Universitat Politècnica de Catalunya, 2021-07-08)
      Doctoral thesis
      Open Access
      Nowadays. 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 Access
      For 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 Access
      When 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 Access
      Thermally 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 Access
      This 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 Access
      We 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 Access
      Epoxy 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 Access
      To 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 ...
