Modification of Graphene Oxide Aerogel Monolith by Gamma Irradiation.

In this work, monolithic graphene oxide aerogel (GOA) with a volume of about 4 cm was obtained. In order to modify its properties, the GOA samples were irradiated with Co gamma rays with doses from 10 to 220 kGy. By using XPS it was found that the oxygen/carbon ratio in the samples studied decreases as a result of irradiation.

Degradation of Polymer Films of Sodium Alginate during Prolonged Irradiation with X-ray under Ultra-High Vacuum.

Sodium alginate (NaAlg) is widely used as a food additive. To study the effect of irradiation with X-ray quanta with energies of 1253.6 eV and 1486.

Hydrophobization of Reduced Graphene Oxide Aerogel Using Soy Wax to Improve Sorption Properties.

A special technique has been developed for producing a composite aerogel which consists of graphene oxide and soy wax (GO/wax). The reduction of graphene oxide was carried out by the stepwise heating of this aerogel to 250 °C. The aerogel obtained in the process of the stepwise thermal treatment of rGO/wax was studied by IR and Raman spectroscopy, scanning electron microscopy, and thermogravimetry.

On the State of Graphene Oxide Nanosheet in a Polyurethane Matrix.

Thermally stable films were obtained from a water-based polyurethane (PU) dispersion with small (0.1-1.5 wt.

Mechanical and Water Absorption Properties of Waterborne Polyurethane/Graphene Oxide Composites.

Nanocomposites based on waterborne polyurethane (WPU) and graphene oxide (GO) have been synthesized and characterized. It was found that after the incorporation of GO, WPU films became mechanically more rigid, and the Young's modulus increased by almost six times. It is shown that the lateral size of GO sheets influences the mechanical properties of WPU/GO composites.
