Reattachment of crosslinked poly(ethylene oxide) via chain interpenetration and reentanglement induced by a simple wetting process

摘要: Abstract We demonstrate the reattachment of two chemically-crosslinked poly(ethylene oxide) (PEO) matrix samples prepared with γ-ray irradiation method by a simple wetting process good solvent. The fractured polymer can be attached through chain diffusion, interpenetration into crosslinked network, and intermixing/reentanglement. Reattached exhibit similar macro/microstructure mechanical properties to those pristine samples. This effective recovery without any additional reactive chemicals or external stimuli highlights importance extending use simple, but fundamental, dynamic behaviors chains obtain desired as well offering unique useful route toward healable materials.
