Effect of γ-irradiation on surface morphology, microstructure and diffuse reflectance of polytetrafluoroethylene
The effect of γ-irradiation on the structural, morphological and optical properties of polytetrafluoroethylene was studied at an absorbed dose of 0.1 kGy. It has been shown that such a dose leads to an increase in the diffuse reflectance coefficient by 28% in the spectral range of 220–850 nm. The maximum effect is observed in the wavelength range from 300 to 400 nm. A correlation between radiation-induced changes in the surface microstructure and the enhancement of light reflection from γ-irradiated PTFE was established.
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.
