Abstract

Hydroxyethyl methacrylate (HEMA) grafted linear low-density polyethylene (LLDPE) films were prepared via pre-treatment method. The non-polar LLDPE films were activated by low-energy electron beam (EB) treatment in vacuum and air at room temperature. The influence of the atmosphere during the EB activation of LLDPE films at fixed dose rate and dose per pass on the grafting process at room temperature were studied at well-selected grafting conditions. Non-polar LLDPE and polar HEMA were selected due to their significant differences in polarity and surface energy. After identification of the optimum atmosphere during low-energy EB activation of LLDPE films, the influence of well-known grafting parameters such as temperature and solvent was studied. The grafting effect of the EB pre-treatment method was investigated by the Relative Grafting Yield (RGY), the static contact angle measurement, the Attenuated Total Reflectance Fourier Transform Infrared spectroscopy, X-ray photoelectron spectroscopy, Scanning Electron Microscopy, and Thermogravimetric analysis.

期刊介绍： Radiation Physics and Chemistry is a multidisciplinary journal that provides a medium for publication of substantial and original papers, reviews, and short communications which focus on research and developments involving ionizing radiation in radiation physics, radiation chemistry and radiation processing. The journal aims to publish papers with significance to an international audience, containing substantial novelty and scientific impact. The Editors reserve the rights to reject, with or without external review, papers that do not meet these criteria. This could include papers that are very similar to previous publications, only with changed target substrates, employed materials, analyzed sites and experimental methods, report results without presenting new insights and/or hypothesis testing, or do not focus on the radiation effects.
