TL;DR: In this article, the effects of gamma and electron irradiation on virgin and recycled polyethylene were compared and their mechanical, thermal and chemical properties were analyzed, showing that VPE samples showed higher crosslinking percentages than RPE samples in all range of doses studied, unirradiated RPE sample had higher values on their tensile properties than VPE.

TL;DR: An analysis of the free radical decay as a function of time and temperature shows the contribution of at least three types of radicals, whose half-lifes, radiochemical yields and activation energies are given.

TL;DR: A review of radiation-based recycling research is provided in this paper, followed by a discussion of future directions where irradiation may be relevant to the problems currently inhibiting the widespread recycling of polymeric materials.

TL;DR: Grafting of polymer chains able to establish specific interactions with the drug, grafting of stimuli-responsive networks that regulate drug diffusion through the hydrogel-type surface as a function of the surrounding conditions, and grafts of cyclodextrins that control uptake and delivery through the affinity constant of inclusion complexes have been revealed as efficient approaches for endowing medical devices with the capability of also acting as drug delivery systems.

TL;DR: In this article, the influence of temperature and pH on the response of binary graft films produced by gamma irradiation in one and two steps was observed by measuring swelling of the films and water contact angle at different temperatures and pH.
