The film is less than 100 nanometers thick and completely transparent to the naked eye. It is also 100 times less permeable to oxygen than existing silicon oxide coatings. &#8220;Others have added clay to polymer to reduce (gas) permeability, but they are thousands of times more permeable than our film,&#8221; Grunlan said. &#8220;We have the most organized structure \u2014 a nano-brick wall \u2014 which is the source of this exceptional barrier. This is truly the most oxygen impermeable film in existence.&#8221; The article can be viewed online at the link below.<\/p>\n<p><a title=\"http:\/\/portal.acs.org\/portal\/acs\/corg\/content?_nfpb=true&amp;_pageLabel=PP_ARTICLEMAIN&amp;node_id=222&amp;content_id=CNBP_026937&amp;use_sec=true&amp;sec_url_var=region1&amp;__uuid=a4834ec3-e33f-445e-ba83-e445f3e77a5a\" href=\"http:\/\/portal.acs.org\/portal\/acs\/corg\/content?_nfpb=true&amp;_pageLabel=PP_ARTICLEMAIN&amp;node_id=222&amp;content_id=CNBP_026937&amp;use_sec=true&amp;sec_url_var=region1&amp;__uuid=a4834ec3-e33f-445e-ba83-e445f3e77a5a\">http:\/\/portal.acs.org\/portal\/acs\/corg\/content?_nfpb=true&amp;_pageLabel=PP_ARTICLEMAIN&amp;node_id=222&amp;content_id=CNBP_026937&amp;use_sec=true&amp;sec_url_var=region1&amp;__uuid=a4834ec3-e33f-445e-ba83-e445f3e77a5a<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>A new material containing an ingredient used to make bricks shows promise as a transparent coating for improving the strength [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"site-sidebar-layout":"default","site-content-layout":"","ast-site-content-layout":"default","site-content-style":"default","site-sidebar-style":"default","ast-global-header-display":"","ast-banner-title-visibility":"","ast-main-header-display":"","ast-hfb-above-header-display":"","ast-hfb-below-header-display":"","ast-hfb-mobile-header-display":"","site-post-title":"","ast-breadcrumbs-content":"","ast-featured-img":"","footer-sml-layout":"","ast-disable-related-posts":"","theme-transparent-header-meta":"","adv-header-id-meta":"","stick-header-meta":"","header-above-stick-meta":"","header-main-stick-meta":"","header-below-stick-meta":"","astra-migrate-meta-layouts":"default","ast-page-background-enabled":"default","ast-page-background-meta":{"desktop":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"ast-content-background-meta":{"desktop":{"background-color":"var(--ast-global-color-4)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"var(--ast-global-color-4)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"var(--ast-global-color-4)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"footnotes":""},"categories":[34],"tags":[],"class_list":["post-2073","post","type-post","status-publish","format-standard","hentry","category-technology-update"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.5 -
