Chemical cross linking versus high energy electron beam cross linking of HDPE: electrical properties study
Cross linking of high density polyethylene (HDPE) was first performed via high energy10 Mev electron beam (EB) irradiation. HDPE was also cross linked withDicumyle peroxide (DCP).The gel content of samples was determined by solvent extraction.Degree of cross linking was evaluated by hot set apparatus; as well .In order to clarify the effectof nature of cross linking, correlation of electrical p...
متن کاملThe Photoacoustic Spectroscopy Applied in the Characterization of the Cross-linking Process in Polymeric Materials
In this work we used the Photoacoustic Spectroscopy (PAS) to evaluate the crosslinking of the copolymer from ethylene vinyl trimethoxysilane (EVS) and the grafted vinyl trimethoxysilane (VTS) on low density polyethylene (LDPE). PAS is used for sounding the overtone bands and stretching frequencies combinations of the groupings -Si-OH, =CH2, -CH3 and -CH2-CH3, in the near and medium infrared ran...
متن کاملcollagen cross-linking
patients with keratoconus constitute a large proportion of patients suffering from anterior segment disorders. as of this time, however, its pathogenesis has not yet been elucidated. a reduction in cross-link between collagen molecules has been observed in keratoconic eyes as compared to normal ones. present approaches only address refractive errors resulting from the abnormal abnormal corneal ...
متن کاملCharacterization of Cross-Linking Depth for Thin Polymeric Films Using Atomic Force Microscopy
Thin polymeric films made with various elastomers, like polyisoprene, and elastomer composites were prepared for characterization of cross-linking depth in this study. Various cross-linking methods have been applied to get mechanically stronger, more thermally stable and chemically resistant polymer coatings. However, there is no existing approach that could effectively characterize the degree ...
