“…Another approach suggested that the main contribution to conduction is given by water diffusion through the porous network resulting in ion conductivity (5,15), such as with the increase of the conductive filler content, the electrical conductivity increases gradually because the conductive solutions promote the elongation and connection of the conductive passages (16).…”

Smart construction materials are intelligent composites that have properties different from normal materials. The smartness of building materials and structures is achieved through material composition design, special processing, the introduction of other functional components, or modification of the microstructure. Conductive concrete is one of the smart construction materials. It is a mixture containing a certain amount of electrically conductive components (filler). It is designed to enable the conduction of electricity. When the conductive filler used is a natural material, the result is green conductive concrete. The current work deals with a review that summarizes the vital points of the incorporation of conductive fillers in construction materials. The types of conductive filler, including green ones, the methods of production, testing, and applications of conductive cement-based composites are addressed and highlighted. Conclusions are made according to the literature reviewed, and some points of view are proposed for future perspectives.

“…Polymer materials are widely used in many important fields such as aerospace, [235] electronics, [236,237] pharmaceutical carriers, [238,239] chemical industry [240] and other important fields [241] because of these materials have the advantages of light weight, high dispersion, easy modification, and corrosion resistance. [242][243][244] The composite materials prepared with boron nitride as filler can combine the advantages of boron nitride and polymer, so as to obtain the composite materials with excellent comprehensive properties.…”

Due to special non-metallic polar bond between the III group (with certain metallic properties) element boron (B) and the V group element nitrogen (N), boron nitride (BN) has unique physical and chemical properties such as strong high-temperature resistance, oxidation resistance, heat conduction, electrical insulation and neutron absorption. Its unique lamellar, reticular and tubular morphologies and physicochemical properties make it attractive in the fields of adsorption, catalysis, hydrogen storage, thermal conduction, insulation, dielectric substrate of electronic devices, radiation protection, polymer composites, medicine, etc. Therefore, the synthesis and properties of BN derived materials become the main research hotspots of lowdimensional nanomaterials. This paper reviews the synthetic methods, overall properties, and applications of BN nanostructures and nanocomposites. In addition, challenges and prospect of this kind of materials are discussed.

The different configurations of the composites originated with machine or human motion, and their mechanical stability for wearable electronics is in focus. Here, the study highlights that these configurations are critical for wearable devices. To achieve these aspects, the electroactive and dielectric silicone rubber (SR) was used as a host matrix. This SR not only provides flexibility, twisting, or stretchability for such devices, but its lightweight makes them comfortable for robust wearable devices. The reinforcing fillers such as graphite nanoplatelets (GNP) or diatomaceous earth (DE) and their hybrids are used. The electromechanical properties of the device were performed using the universal testing machine. The output voltage generated at 15 phr filler was 0.3 mV (GNP), 0.15 mV (DE), and 0.22 mV (hybrid). Similarly, the biomechanical properties were studied with human motion joints such as thumb pressing or wrist bending. The output voltage at 15 phr was best for thumb pressing and it was 0.42 mV (GNP), 0.18 mV (DE), and 0.25 mV (hybrid). In the same way, the mechanical aspects studied in this work are compressive modulus, tensile strength, and fracture strain. For example, the compressive modulus was 1.28 MPa (control) and increased at 15 phr filler to 2.44 MPa (GNP), 3.2 MPa (DE), and 2.75 MPa (hybrid). Similarly, the mechanical stretchability of the devices was 134% (control) and changed at 15 phr filler to 128% (GNP), 78% (DE), and 109% (hybrid). Overall, the work demonstrates the method to develop a device with high mechanical, electromechanical, and biomechanical properties and their usefulness for wearable electronic devices.
