A photolatent base ((1,5-diazabicyclo [4.3.0]non-5-ene) DBN) is used for the first time as photocatalyst for the curing of a formulation, which undergoes crosslinking by Michael addition reaction between acetoacetate and acrylate groups together with the reduction of graphene oxide. The reduction degree of graphene oxide during in situ irradiation is monitored by XPS analysis. The effect of the graphene oxide concentration on the photopolymerization reaction is studied by RT-FTIR. The thermal properties of the composite are determined by DSC analyses. The crosslinked nanocomposite showed a decrease of one order of magnitude for the electrical resistance in the presence of 3 wt% of graphene oxide. In addition, the thermal conductivity is significantly increased by the in situ reduction of graphene oxide in the organic matrix catalyzed by the phototriggered base. (C) 2016 Elsevier Ltd.
