Abstract Reinforcement of the flexible shielding properties of natural rubber (NRL) was achieved through various content Multi-walled carbon nanotubes (MWCNTs) prepared from a simple solution using mixing method. Thereafter, a host of evaluative tests, using different techniques were carried to check the structural, morphological, mechanical and electrical conformity of the MWCNTs in the natural rubber matrix. More notably, the results from the x-ray diffraction (XRD), Scanning electron microscopy (SEM) and Fourier-transform infrared spectroscopy (FTIR) revealed that the nanocomposites have been successfully prepared, making them fitting to impact significant improvement on the mechanical strength of the matrix. The evaluation of the formation of MWCNT networks in the matrix, which gives insight into the nanocomposites' electrical conductivity, also showed agreeable results as the linear attenuation coefficients (l) and half-value thickness (HVT) for NRL/MWCNTs nanocomposite films were investigated . Thus, from the foregoing series of results, it can be concluded that nanocomposite films offer promising radiation-shielding properties.

AbstractThe present study is focused on the development and characterization of innovative cementitious-based composite sensors. In particular, multifunctional cement mortars with enhanced piezoresistive properties are realized by exploiting the concept of confinement of Multiwall Carbon Nanotubes (MWCNTs) and reduced Graphene Oxide (rGO) in a three-dimensional percolated network through the use of a natural-rubber latex aqueous dispersion. The manufactured cement-based composites were characterized by means of Inelastic Neutron Scattering to assess the hydration reactions and the interactions between natural rubber and the hydrated-cement phases and by Scanning Electron Microscopy and X-Ray diffraction to evaluate the morphological and mineralogical structure, respectively. Piezo-resistive properties to assess electro-mechanical behavior in strain condition are also measured. The results show that the presence of natural rubber latex allows to obtain a three-dimensional rGO/MWCNTs segregate structure which catalyzes the formation of hydrated phases of the cement and increases the piezo-resistive sensitivity of mortar composites, representing a reliable approach in developing innovative mortar-based piezoresistive strain sensors.
