Mechanically Triggered Chemical Recyclable Polyethylene-Like Materials. [PDF]
Angew Chem Int Ed EnglPolyethylene‐like copolymers with benchmark properties are prepared by embedding latent cyclobutene mechanophores to overcome PE's end‐of‐life limits. The mechanophores are inert in service but are selectively opened by solvent‐free ball milling to yield well‐defined telechelic oligomers.

Longitudinal AC breakdown voltage of XLPE-XLPE interfaces considering surface roughness and pressure [PDF]
IEEE Transactions on Dielectrics and Electrical Insulation, 2017 The interfacial breakdown between two dielectric surfaces has been reported to represent one of the principal causes of failure for power cable joints and connectors; thus, a better understanding of interfacial breakdown mechanisms is vital. The primary purpose of this paper is to investigate the influence of the surface roughness and interfacial ...
