Material Extrusion Additive Manufacturing with Polyethylene Vitrimers

open access: yesPolymers, 2023
Polyethylene (PE) is one of the most widely used polymers in conventional polymer manufacturing processes. However, it remains a challenge to use PE in extrusion-based additive manufacturing (AM). Some of the challenges that this material presents include low self-adhesion and shrinkage during the printing process.

Closed-loop recycling of polyethylene-like materials [PDF]

open access: yesNature, 2021
Plastics are key components of almost any technology today. Although their production consumes substantial feedstock resources, plastics are largely disposed of after their service life. In terms of a circular economy1-8, reuse of post-consumer sorted polymers ('mechanical recycling') is hampered by deterioration of materials performance9,10.

NON-BIODEGRADATION OF POLYMERIZED POLYETHYLENE RADICALS AT SELECTED DUMPSITES IN KEFFI, NASARAWA STATE NIGERIA [PDF]

open access: yesJournal CleanWAS, 2023
Polythene and plastic bags pollutes the soil because these are non-biodegradable, and so, they cannot be degraded by the action of the microbes. Therefore, they remain in the soil and will pollute the soil.

Highly cross‐linked polyethylene is the new ‘gold standard’ bearing material for total hip arthroplasty

open access: yesBiosurface and Biotribology, 2021
Conventional polyethylene is not used much in total hip arthroplasty (THA); it has been supplanted by oxidation‐resistant cross‐linked polyethylene (≥50 kGy irradiation). However, studies persist that de‐emphasize or ignore cross‐linked polyethylene.
