“…Indeed, such highly energetic irradiations yield bond cleavages and free radicals allowing chemical rearrangements or oxidation in the presence of air, crosslinking and further chain scission reactions in the g-irradiated material. These modifications are closely linked with the g-irradiation conditions such as the dose rate, the integral dose delivered, the nature of the atmosphere or the temperature [14,13,8,31,38].…”

“…While the material safety data sheet claims that the PE-based WPC is manufactured with plastics obtained primarily from reclaimed/recycled grocery bags and stretch film, there is a chance that other types of PE are mixed in with the LLDPE. In this case, the crosslinkability could vary, because low-density PE and high-density PE have G-values (events per 100 eV) ranging from 0.5 to 1.09 (Dawes et al 2007).…”

The focus of this study was to examine the potential benefits of irradiating polyethylene (PE)-based wood-plastic composites (WPCs) in order to enhance the mechanical properties of the WPC. The PE-based WPCs were irradiated, post extrusion, at dose levels of 0, 50, 100, 150, 200, and 250 kGy with an electron beam (EB). The irradiated WPCs were then evaluated using a third point bending test (ASTM D4761) along with scanning electron microscopy (SEM). It was found that ultimate strength and modulus of elasticity (MOE) increased with increasing dose level. Examination of the fracture surfaces of polyethylene revealed a distinct difference in failure between irradiated and non-irradiated surfaces.

“…[1] However, polymers are sensitive to exposure to X-rays and electrons raising the possibility of significant sample degradation during the time required for analysis. [2][3][4][5][6][7][8][9][10] XPS imaging analysis can cause extensive damage to polymers. In order to achieve the quantified images, each elemental image would be acquired in such a way that a spectrum is available at each pixel.…”

The recent development of X‐ray Photoelectron Spectroscopy (XPS) instrumentation with spatial resolution down to several microns has advanced the capability of elemental and chemical state imaging. XPS imaging analysis has been applied in understanding the delamination problems of siloxane coatings on polymethyl‐methacrylate (PMMA) polymer. It was found that delamination occurred by interfacial failure, and the coating suffered complete delamination from a PMMA substrate. This example offered an opportunity for the investigation of X‐ray damage on polymers encountered in XPS imaging analysis. This paper also demonstrated how to construct a constrained peak model with the aid of chemical knowledge and supporting evidence of the sample. Monte Carlo error analysis was used to determine the validity of the peak fit models used. Copyright © 2013 John Wiley & Sons, Ltd.
