SiO2-Np was added at varying ratios from 1 to 4 wt.% to improve the bonding performance of the RPF resins. The physical characteristics of the nano-modified RPF (nano-RPF) resins were examined. The effects of modification were studied by Fourier transform infrared spectroscopy (FT-IR) and thermogravimetric analysis (TGA). The results of FT-IR revealed that the nano-RPF resins were successfully produced by phenol, formaldehyde, and SiO2-Np. The nano-RPF resins demonstrated high thermal stability at temperatures above 500\u00b0C. The adhesive performance of the nano-RPF resins was investigated under dry and wet conditions. The nano-RPF resins indicated better adhesive performance than unmodified RPF resin. The RPF resin could be improved by SiO2-Np.<\/p>\n","protected":false},"author":4,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[48],"tags":[227,226,225,228],"release_year":[],"ppma_author":[222,223,224],"class_list":["post-1867","post","type-post","status-publish","format-standard","hentry","category-wood-research-volume-66-number-1-2021","tag-adhesive-performance","tag-phenol-formaldehyde","tag-silica-nanoparticles","tag-thermal-stability"],"featured_image_src":null,"author_info":{"display_name":"Maro\u0161 Kov\u00e1\u010d","author_link":"https:\/\/www.woodresearch.sk\/cms\/author\/kovacvupc-sk\/"},"authors":[{"term_id":222,"user_id":0,"is_guest":1,"slug":"gunay-ozbay","display_name":"G\u00fcnay \u00d6zbay","avatar_url":"https:\/\/secure.gravatar.com\/avatar\/?s=96&d=mm&r=g","0":null,"1":"","2":"","3":"","4":"","5":"","6":"","7":"","8":""},{"term_id":223,"user_id":0,"is_guest":1,"slug":"erkan-sami-kokten","display_name":"Erkan Sami Kokten","avatar_url":"https:\/\/secure.gravatar.com\/avatar\/?s=96&d=mm&r=g","0":null,"1":"","2":"","3":"","4":"","5":"","6":"","7":"","8":""},{"term_id":224,"user_id":0,"is_guest":1,"slug":"ayhan-ozcifci","display_name":"Ayhan Ozcifci","avatar_url":"https:\/\/secure.gravatar.com\/avatar\/?s=96&d=mm&r=g","0":null,"1":"","2":"","3":"","4":"","5":"","6":"","7":"","8":""}],"_links":{"self":[{"href":"https:\/\/www.woodresearch.sk\/cms\/wp-json\/wp\/v2\/posts\/1867","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.woodresearch.sk\/cms\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.woodresearch.sk\/cms\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.woodresearch.sk\/cms\/wp-json\/wp\/v2\/users\/4"}],"replies":[{"embeddable":true,"href":"https:\/\/www.woodresearch.sk\/cms\/wp-json\/wp\/v2\/comments?post=1867"}],"version-history":[{"count":2,"href":"https:\/\/www.woodresearch.sk\/cms\/wp-json\/wp\/v2\/posts\/1867\/revisions"}],"predecessor-version":[{"id":2183,"href":"https:\/\/www.woodresearch.sk\/cms\/wp-json\/wp\/v2\/posts\/1867\/revisions\/2183"}],"wp:attachment":[{"href":"https:\/\/www.woodresearch.sk\/cms\/wp-json\/wp\/v2\/media?parent=1867"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.woodresearch.sk\/cms\/wp-json\/wp\/v2\/categories?post=1867"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.woodresearch.sk\/cms\/wp-json\/wp\/v2\/tags?post=1867"},{"taxonomy":"release_year","embeddable":true,"href":"https:\/\/www.woodresearch.sk\/cms\/wp-json\/wp\/v2\/release_year?post=1867"},{"taxonomy":"author","embeddable":true,"href":"https:\/\/www.woodresearch.sk\/cms\/wp-json\/wp\/v2\/ppma_author?post=1867"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
