초록
In this study, we demonstrated that low-density polyethylene (LDPE)/octaphenyl polyhedraloligomeric silsequioxanes (phPOSS) nanocomposites exhibited the improved radiation resistancein comparision to that of pure LDPE. The LDPE/phPOSS nanocomposites were prepared bymelt blending at the different compositions and then exposed to γ-irradiation at the various dosesranging from 50 to 500 kGy. The radiation resistance of the irradiated nanocomposites were investigatedin terms of tensile property, oxygen induction temperature, decomposition temperature,and oxidation extent. The various analytical results revealed that the incorporation of phPOSS intothe LDPE matrix could enhance the radiation resistance of pure LDPE because of the protectiveeffect of the phenyl groups existing in the phPOSS. This simple and effective strategy can be usedin the development of new radiation-resistant materials for the equipments and components ofnuclear power plants.
