We present practical designs to construct a CDT system from commonly available parts and detail calibrations performed on different fabrics to study their electrocharging characteristics. After confirming the post-CDT structural integrity of fabrics, measurements showed that all non-woven polymer electret and only some knitted cloth fabrics are capable of charge retention. Whereas polymeric fabrics follow the well-known isothermal charging route, ion adsorption causes electrocharging in knitted cloth fabrics. Filtration tests demonstrate improved steady filtration efficiency in non-woven polymer electret filters. On the other hand, knitted cloth fabric filters capable of charge retention start with improved filtration efficiency which decays in time over up to 7 h depending on the fabric type, with filtration efficiency tracking the electric discharge. A rapid recharge for a few seconds ensures FM reuse over multiple cycles without degradation.","subitem_description_type":"Other"}]},"item_10001_publisher_8":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_publisher":"The Royal Society"}]},"item_10001_relation_13":{"attribute_name":"PubMedNo.","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"info:pmid/34276243","subitem_relation_type_select":"PMID"}}]},"item_10001_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"info:doi/10.1098/rspa.2021.0062","subitem_relation_type_select":"DOI"}}]},"item_10001_relation_17":{"attribute_name":"Related site","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://royalsocietypublishing.org/doi/10.1098/rspa.2021.0062","subitem_relation_type_select":"URI"}}]},"item_10001_rights_15":{"attribute_name":"Rights","attribute_value_mlt":[{"subitem_rights":"© 2021 The Author(s)"}]},"item_10001_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"1364-5021","subitem_source_identifier_type":"ISSN"},{"subitem_source_identifier":"1471-2946","subitem_source_identifier_type":"ISSN"}]},"item_10001_version_type_20":{"attribute_name":"Author's flag","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2021-09-06"}],"displaytype":"detail","filename":"rspa20210062.pdf","filesize":[{"value":"1.5 MB"}],"format":"application/pdf","license_note":"CC BY 4.0\nCreative Commons Attribution 4.0 International (https://creativecommons.org/licenses/by/4.0/)","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"rspa.2021.0062","url":"https://oist.repo.nii.ac.jp/record/2230/files/rspa20210062.pdf"},"version_id":"23c6b418-9db0-4bb5-98ef-65f21737a68a"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"electrocharged","subitem_subject_scheme":"Other"},{"subitem_subject":"respirator","subitem_subject_scheme":"Other"},{"subitem_subject":"face masks","subitem_subject_scheme":"Other"},{"subitem_subject":"cloth fabrics","subitem_subject_scheme":"Other"},{"subitem_subject":"PLASMA","subitem_subject_scheme":"Other"},{"subitem_subject":"ADSORPTION","subitem_subject_scheme":"Other"},{"subitem_subject":"SURFACES","subitem_subject_scheme":"Other"}]},"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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Electrocharging face masks with corona discharge treatment","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Electrocharging face masks with corona discharge treatment","subitem_title_language":"en"}]},"item_type_id":"10001","owner":"31","path":["15"],"pubdate":{"attribute_name":"公開日","attribute_value":"2021-09-06"},"publish_date":"2021-09-06","publish_status":"0","recid":"2230","relation_version_is_last":true,"title":["Electrocharging face masks with corona discharge treatment"],"weko_creator_id":"31","weko_shared_id":31},"updated":"2023-06-26T11:34:39.485588+00:00"}
