Resumo:
The present study aims to explore the synergy between the properties of nanoparticles in hybrid nanocomposites. The intention is to assess how the interaction among these nanoparticles influences the properties of the nanocomposites. To achieve this, a combination of carbon black (CB) and graphene (G) integrated into an epoxy resin matrix (DGEBA) will be utilized. The formulation will adopt a mass ratio of 1% for each nanoparticle. The preparation of the nanocomposites will occur in situ, followed by a curing process at 60°C for 24 hours, followed by a post-curing step at 100°C for 1 hour. Comprehensive analyses will be conducted, addressing thermal, mechanical, and morphological aspects of the resulting nanocomposites. The main objective is to evaluate the rupture strength and Young's modulus (E), aiming to identify whether there was adhesion between the resin and the nanoparticles, specifically carbon black/graphene. Transmission electron microscopy (TEM) analyses will be carried out to examine the distribution of carbon black nanoparticles among the layers of graphene. Additionally, the use of optical microscopy will enable the evaluation of the dispersion of nanoparticles in the matrix. With these detailed analyses, it is believed that it will be possible to gain an understanding of the interactions among the hybrid nanoparticles of the nanocomposite, providing insights into their mechanical strength, thermal stability, and other relevant properties. Such information is essential for the development of advanced composite materials with applicability in various sectors, including electronics, structural materials, and protective coatings.
