“…It is important to note that the nanostructured materials can be produced and coated or painted practically, to conform to any shape of interest [22,[40][41][42]. Therefore, they can be applied when producing different radiation protection equipment, such as thyroid shields and protective aprons.…”

Exposure to ionizing radiation (IR) during diagnostic medical procedures brings certain risks, especially when experiencing recurrent exposures. The fabrication of nano-based composites, doped with different nanoparticles, have been suggested as effective shielding materials to replace conventional lead-based ones in material sciences and nanotechnology. In this study, commercially available fabrics, used to produce scrubs and gowns for clinical staff, are modified utilizing graphene oxide (GO) nanoparticles using a layer-by-layer (LBL) technique. GO was obtained from graphite through environmentally friendly technology by using a modified–improved Hummers’ method without NaNO3. Lightweight, flexible, air- and water-permeable shielding materials are produced that are wearable in all-day clinical practice. The nanoparticles are kept to a minimum at 1 wt%; however, utilizing the LBL technique they are distributed evenly along the fibers of the fabrics to achieve as much shielding effect as possible. The evaluation of samples is accomplished by simulating real-time routine clinical procedures and the radiographic programs and devices used daily. The GO-coated nanocomposite fabrics demonstrated promising results for X-ray shielding.

“…Less impacting solutions have been practiced since the spreading of nano-reinforcements occurred. Indeed, they can be used to achieve the desired effects by adding low quantities 15 – 17 , thus benefitting from negligible composite size and weight changes. Adding nanoparticles 18 , 19 and carbon nanotubes (CNTs) 20 – 23 proved to boost the composite performance.…”

Nanofibrous mats provide substantial delamination hindering in composite laminates, especially if the polymer (as rubbers) can directly toughen the composite resin. Here, the well-known Nylon 66 nanofibers were impregnated with Nitrile Butadiene Rubber (NBR) for producing rubber/thermoplastic membranes for hampering the delamination of epoxy Carbon Fiber Reinforced Polymers (CFRPs). The starting polyamide mats were electrospun using two different solvent systems, and their effect on the mat's thermal and mechanical properties was investigated, as well as the laminate Mode I delamination resistance via Double Cantilever Beam (DCB) tests. Plain Nylon 66 mats electrospun from formic acid/chloroform perform better than the ones obtained from a solvent system containing trifluoroacetic acid, showing up to + 64% vs + 53% in interlaminar fracture toughness (GI), respectively. The effect of NBR coating benefits both nanofiber types, significantly raising the GI. The best results are obtained when interleaving medium-thickness and lightweight mats (20 µm, 9–10 g/m2) with 70–80 wt% of loaded rubber, achieving up to + 180% in GI. The work demonstrates the ability of NBR at improving the delamination hindering of common polyamide nonwovens, paving the way to the use of NBR-coated Nylon 66 nanofibers as effective interleaves for GI enhancement and overall composite safety improvement.

“…, graphene and montmorillonite), and it is found that there is a strong interaction between the two components, and the graphene oxide/MMT hybrid can be dispersed in water synergistically to enhance the mechanical properties, thermal stability and flame retardancy of the composite aerogel. Veerendra 14 prepared three-dimensional flame retardant carbon–carbon nanotubes mixed foam. It was found that the addition of three-dimensional flame retardant carbon–carbon nanotubes in phenolic resin could not only improve the compressive strength (6.5 MPa), but also improve the thermal stability and flame retardant performance.…”
