In order to clarify the effects of interface, thermally stimulated current (TSC), conduction current and dielectric breakdown measurements were carried out on the composite of EVA (ethylene-vinyl acetate copolymer) and PE (polyethylene) and also on other combination of polymer materials. The TSC and conduction current in EVA-PE showed remarkable dependence on the polarity of the applied voltage, which cannot be explained by the simple Maxwell- Wagner model. This is explained as follows. Positive carriers are easily injected into EVA from the Au anode. Some of them are trapped at the EVA-PE interface and give rise to a new interfacial TSC peak. Most of the positive carriers can pass through the interface and move in the PE layer, increasing the conduction current in PE by about two orders of magnitude. The conduction current measurements also revealed that the existence of some polar groups at the metal-PE interface enhances carrier injection into PE. Methods were proposed for analyzing the internal fields in the composite system to which the simple Maxwell-Wagner model could not be applied. The internal field under very high field near dielectric breakdown strength was estimated from the breakdown strength of the composite. The internal field under lower fields was estimated by the separation method developed here. It was revealed that the ratio of internal fields of PE and EVA layers dependes on the polarity, field and temperature. The latter method also clarified that the positive carriers trapped at the EVA-PE interface were located on the EVA side. Other combinations of polymers also showed the same polarity dependence as EVA-PE, suggesting that EVA-PE was not an exceptional case but that similar phenomena also took place in practical insulating composites.", "subitem_description_language": "en", "subitem_description_type": "Abstract"}]}, "item_9_identifier_registration": {"attribute_name": "ID登録", "attribute_value_mlt": [{"subitem_identifier_reg_text": "10.18999/memfenu.38.2.137", "subitem_identifier_reg_type": "JaLC"}]}, "item_9_publisher_32": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "Faculty of Engineering, Nagoya University", "subitem_publisher_language": "en"}]}, "item_9_select_15": {"attribute_name": "著者版フラグ", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "item_9_source_id_7": {"attribute_name": "ISSN（print）", "attribute_value_mlt": [{"subitem_source_identifier": "0027-7657", "subitem_source_identifier_type": "PISSN"}]}, "item_access_right": {"attribute_name": "アクセス権", "attribute_value_mlt": [{"subitem_access_right": "open access", "subitem_access_right_uri": "http://purl.org/coar/access_right/c_abf2"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Ieda, Masayuki", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "102048", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Cai, Guo-xiong", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "102049", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Suzuoki, Yasuo", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "102050", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Mizutani, Teruyoshi", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "102051", "nameIdentifierScheme": "WEKO"}]}]}, "item_files": {"attribute_name": "ファイル情報", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2020-11-04"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "38-2-01.pdf", "filesize": [{"value": "4.9 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_note", "mimetype": "application/pdf", "size": 4900000.0, "url": {"label": "38-2-01.pdf", "objectType": "fulltext", "url": "https://nagoya.repo.nii.ac.jp/record/30767/files/38-2-01.pdf"}, "version_id": "99469963-97f1-4bec-992a-c109cf769f5f"}]}, "item_language": {"attribute_name": "言語", "attribute_value_mlt": [{"subitem_language": "eng"}]}, "item_resource_type": {"attribute_name": "資源タイプ", "attribute_value_mlt": [{"resourcetype": "departmental bulletin paper", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_title": "Effects of polymer-polymer interfaces on electrical properties of insulationg composites", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Effects of polymer-polymer interfaces on electrical properties of insulationg composites", "subitem_title_language": "en"}]}, "item_type_id": "9", "owner": "1", "path": ["2555"], "permalink_uri": "https://doi.org/10.18999/memfenu.38.2.137", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2020-11-04"}, "publish_date": "2020-11-04", "publish_status": "0", "recid": "30767", "relation": {}, "relation_version_is_last": true, "title": ["Effects of polymer-polymer interfaces on electrical properties of insulationg composites"], "weko_shared_id": -1}
