Structural and dielectric properties of copper ferrite/LDPE composite

In this paper, the interface microstructure, elements’ diffusion features at the interface, and bonding properties in nickel-based alloy/carbon steel clad composite prepared by vacuum hot-roll bonding were investigated, comprehensively. The influence of element distribution on the interface bonding strength was revealed as well. The results showed that there was a 13 μm thick diffusion layer at the interface of nickel-based alloy/carbon steel composite plate, which was beneficial to a strong bond between nickel-based alloy and carbon steel, as well as the stable transition of mechanical properties in the thickness direction. Kirkendall voids and fine-grained structure (the grain size is about 41.5 nm) were observable by peeling off the nickel-based alloy cladding, which greatly promoted element diffusion and enhanced the interfacial bonding strength of the nickel-based alloy/carbon steel composite plate. The diffusion coefficient of Ni at the interface was about 2 orders of magnitude larger than that of nanocrystalline Fe. The shear strength reached up to 453 MPa, which was much higher than the minimum of 140 MPa defined in ASTM A-264 specifications. Furthermore, in the shear test, the fracture occurred on the X52 carbon steel side at the contact rather than at the composite plate interface.

Low-density polyethylene (LDPE) is generally found in the form of bags that are used to pack or transport merchandise; however, the proper disposal of this non-biodegradable material has been a great challenge, since, worldwide, it is calculated that only 9%, of the 9 billion tons that have been produced so far, has been recycled. In Mexico, it is estimated that 8 million tons of this material will be generated annually and only 14% will be recycled. On the other hand, the recycling of these residues, as an aggregate in construction materials, is considered an environmentally sustainable application. The objective of this article is to develop a methodology for the design of ecological concrete bricks incorporating LDPE from design as part of its aggregates, which will be obtained from articles with results presented, thus seeking to analyze the best design; this as an alternative to bricks commonly found in the construction industry. Although bricks made only with LDPE and sand have given good results, in relation to the use of plastic in intervals of 25 to 50%, it is expected that by adding Portland cement, they will have better physical and mechanical properties.

The distribution structure of dielectric fillers is attracting more attention in designing composites with excellent dielectric properties and energy storage performances. Barium titanate (BT) and polyvinylidene fluoride (PVDF) were introduced to low‐density polyethylene (LDPE) to build the dielectric structure by modulating the phase structure of PVDF/LDPE and the distribution behavior of BT. The results showed that BT particles can be selectively distributed in the phase structure of PVDF/LDPE by controlling the surface modification of BT, which contributed much to the enhancement of dielectric properties and energy storage performances. The dielectric constant and discharge energy density of the composites with the selective distribution of core‐shell structured BT@PE in the LDPE phase of PVDF/LDPE blend were increased by 51% and 95% in comparison with PVDF/LDPE blend, respectively. By simulating with finite element analysis (FEA), the increased internal polarization and the decreased electric field distortion of PVDF/LDPE/BT@PE due to BT@PE distributed in the LDPE phase and the small dielectric constant difference between the LDPE/BT@PE phase and PVDF phase were the factors to enhance the dielectric constant and breakdown strength, which consequently enhance the energy storage performances of the composites.Highlights Phase structure constructed with BT and BT@PE selectively distributed in PVDF/LDPE. Co‐enhanced dielectric constant and breakdown strength of PVDF/LDPE/BT@PE. Modulated polarization and electric field due to BT@PE in the LDPE phase of composites.
