The dielectric properties of water-treed crosslinked polyethylene (XLPE) were studied by using a hollow microwave waveguide system between 135 MHz and 13.6 GH5. The dielectric loss of water-treed XLPE is proportional to water content. Water-treed XLPE has a low relaxation frequency which is probably due to bound water. The binding of water in trees was confirmed by the lower apparent water diff...

Introduction Reduction of ultra high molecular weight polyethylene (UHMWPE) surface wear in total knee replacement (TKR) bearings may delay the onset of osteolysis and subsequent loosening of components. Crosslinking has been shown to increase the wear resistance of UHMWPE bearings in multidirectional total hip replacement applications when articulating against smooth counterfaces [1]. The aim ...

Crosslinked polyethylene (XLPE) has become the globally preferred insulation for power cables, both for distribution and transmission system applications. This insulation system provides cost efficiency in operation and procurement, as well as lower environmental and maintenance requirements when compared to older impregnated paper systems. The purpose of this paper is to outline some of the de...

Stimuli-responsive, polymer-based nanostructures with anisotropic compartments are of great interest as advanced materials because they are capable of switching their shape via environmentally-triggered conformational changes, while maintaining discrete compartments. In this study, a new class of stimuli-responsive, anisotropic nanofiber scaffolds with physically and chemically distinct compart...

We present a simple and widely applicable method to fabricate micro- and nanochannels comprised entirely of crosslinked polyethylene glycol (PEG) by using UV-assisted irreversible sealing to bond partially crosslinked PEG surfaces. The method developed here can be used to form channels as small as approximately 50 nm in diameter without using a sophisticated experimental setup. The manufactured...

Front Cover: In article number 2100383, Ana-Maria Resmerita and co-workers show that incorporation of 5 wt% polystyrene/hydroxypropyl-β-cyclodextrins (HPβCD) semi-rotaxane into a polyethylene glycol/HPβCD crosslinked matrix leads to hydrophobic porous film with enhanced swelling ability thermal dielectric properties as compared those the pure material.

Abstract Recycling of crosslinked plastics is an intractable challenge due to their very limited amenability mechanical reprocessing. While a variety chemical recycling methods have been recently reported, these systems primarily focus on deconstructing or depolymerizing monomers and liquid fuels, which subsequent use likely involves additional energy consumption greenhouse gas emission. In thi...
