The highest degree of water absorption was observed for the composites containing 30 \u2013 50 mass% alkali pre-treated wood flour. For the materials with 50 mass% untreated, silane-treated and alkali pre-treated wood flour, the water absorption measured was 8.76%, 7.84% and 13.91%, respectively, after 15 days immersion in water. The value of the thickness swelling calculated for the samples prepared with 50 mass% silane-treated wood flour \u2013 polypropylene was the lowest \u2013 1.29%.  It was proved that the absorption of water molecules results in change of the tensile profile of the thermoplastic polypropylene composites filled with hygroscopic filler.  <\/p>\n","protected":false},"author":5,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[4581],"tags":[28,4609,4610,350,301],"release_year":[],"ppma_author":[4553,4554,4555],"class_list":["post-4648","post","type-post","status-publish","format-standard","hentry","category-wood-research-volume-68-number-3-2023","tag-mechanical-properties","tag-polypropylene","tag-surface-treatment","tag-water-absorption","tag-wood-flour"],"featured_image_src":null,"author_info":{"display_name":"Stela Sl\u00e1mov\u00e1","author_link":"https:\/\/www.woodresearch.sk\/cms\/author\/slamovavupc-sk\/"},"authors":[{"term_id":4553,"user_id":0,"is_guest":1,"slug":"dimitrina-s-kiryakova","display_name":"Dimitrina S.
