“…For example, PE microspheres have been employed as core materials for fabricating hollow alumina microspheres and non‐porous silica ultramicrospheres for HPLC column packing 1, 2. PE fibers can serve as filtration materials, absorber materials of heavy particle irradiation for space exploration or precursors of carbon fibers in the presence of a catalyst 3–7. Moreover, PE film materials, surface‐modified via plasma irradiation, have found wide applications as support materials for immobilizing DNA, proteins and cells, and as anticoagulants in the development of DNA‐chips, biosensors and extracellular matrix for tissue engineering and vessels.…”

Low density polyethylene (LDPE) was prepared into micro‐ or submicro‐spheres or nanofibers via melt blending or extrusion of cellulose acetate butyrate (CAB)/LDPE immiscible blends and subsequent removal of the CAB matrix. The sizes of the PE spheres or fibers can be successfully controlled by varying the composition ratio and modifying the interfacial properties of the blends. The surface structures of LDPE micro‐ or submicro‐spheres and nanofibers were analyzed using SEM and FTIR‐ATR spectroscopy. In addition, the crystalline structures of the LDPE nanofibers were characterized.magnified image

“…Creation of a composite with appropriate fillers allows to control mechanical properties. Filling polyethylene with lowdensity silicates 82 in the form of hollow glass microspheres results in improving tensile resistance and strength while minimizing the increase in the material's weight, which allows to use these impact-resistance composites for protection against high energy radiations during studies and space exploration. At the same time, addition of pure or functionalized boron nitride (15% vol.)…”

This review describes main types of organic polymers, which are now widely used and are the most resistant to ionizing radiation. It presents modern approaches to creation of radiationshielding composite materials based on polymer matrix and various types of fillers. It also discusses the efficiency of sizes of fillers' micro-and nanoparticles in terms of improving radiation resistance of organic polymer materials.

“…It has been seen that concrete contained polystyrene and boron oxide can improve the neutron shielding . Presence of borosilicate has shown to compensate the weakness of LDPE at high temperature and pressure used for shielding in spacecraft industry . It has been proved that 2 weight percentage of boron nitride (BN) in HDPE can improve the neutron‐beam shielding .…”

Department of polymer processing, Iran polymer and petrochemical institute, Tehran, Iran Shielding radiation from both x-rays and gamma-rays is important for personnel in medical fields, for example, interventional radiology, nuclear power stations, and other facilities where radiation is involved. Lead is known for its effective shielding property; however heaviness and toxicity are its main drawback. In this study effectiveness of non-lead polymeric composite materials, which include high-atomic-number (powders of spherical W and lamellar MoS2)/or known barrier elements to absorb photons from the radiations (lamellar B4C) was evaluated. HDPE and particulate fillers were melt mixed in an internal mixer. Goodness of dispersion was manifested via SEM and EDX images. Radiation attenuation capability of samples was examined with direct diagnostic x-ray exposure. Dynamic rheology measurements were carried out to evaluate viscoelastic properties, necessary in shaping process operations. Mechanical and thermal properties were further investigated from the product performance point of view. Results demonstrated that the flexible composite sheet of HDPE/45% (wt) W provided comparable x-ray absorption to non-flexible lead sheet but much lighter in weight. Significant difference was observed between flow characteristics and yield strength of composite materials of highly loaded spherical and lamellar particles. Melt viscoelastic behavior of former was similar to that of neat matrix melt. POLYM. COMPOS., 00:000-000, 2017.
