Dielectric polymer materials are used extensively in the electrical power transmission industry due to their excellent properties; however, under normal operating conditions, these materials tend to degrade and ultimately fail. In this study, several samples of low density polyethylene, polypropylene, polymethyl methacrylate, polytetrafluorethylene were subjected to corona discharges in air and nitrogen atmospheres. The discharges cause visible structural changes on the polymer surface. From a chemical point of view, the alterations appear to be similar for all non-fluorinated plastics. A corona discharge simulation was also carried out to identify reactive chemical species near the surface. These results are consistent with the degradation of polymers used in high voltage applications due to internal partial discharges that ultimately lead to material failure.<\/p>\n","scarica_file":false,"link_estreno":[{"link_text":"Download ISI Article","link":"https:\/\/www.mdpi.com\/2073-4360\/11\/10\/1646"}],"button":{"text":"","link":""},"referente_group":false,"data_emissione":"2019-10-10","autori":"A.
