To enhance the mechanical and thermal stability of wood-plastic composite phase change materials (WPC PCMs), polyethylene glycol (PEG)\/wood flour (WF) PCMs were prepared via solution impregnation. These were added to cellulose, polycaprolactone (PCL), and polylactic acid (PLA)-blended degradable plastics and then compression-molded into WPC PCMs. The materials were characterized using mechanical and thermal tests (SEM, FT-IR, DSC, TG). Research shows that capillary action enables WF to encapsulate PEG, reducing post-phase transition leakage and facilitating heat storage. As PEG content changes, phase change enthalpy and temperature first decrease, then increase, and finally stabilize, with a high latent heat of 33.97 J\/g. WPC PCMs exhibit good thermal stability with increasing PEG. When the addition amount of PEG was 30%, compared with the initial decomposition temperature and the maximum decomposition temperature of the material without PEG addition, they increased by 24.4\u00b0C and 26.9\u00b0C respectively.PEG increases the thermal conductivity of WPC PCMs within a certain range, but the increase is limited. Due to its simple preparation, WPC PCMs have broad application prospects in solar and biomass energy storage<\/p>\n","protected":false},"author":4,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[5181],"tags":[5246,5245,5247],"release_year":[],"ppma_author":[5239,5240,5241,5242,5243,5244],"class_list":["post-5511","post","type-post","status-publish","format-standard","hentry","category-wood-research-volume-70-number-2-2025","tag-biodegradable","tag-phase-transformation","tag-wood-plastic-composite-phase-change-materials"],"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":5239,"user_id":0,"is_guest":1,"slug":"li-xueli","display_name":"LI XUELI","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":5240,"user_id":0,"is_guest":1,"slug":"zhang-yaoyi","display_name":"ZHANG YAOYI","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":5241,"user_id":0,"is_guest":1,"slug":"zhu-lizhi","display_name":"ZHU LIZHI","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":5242,"user_id":0,"is_guest":1,"slug":"fu-zhiqiang","display_name":"FU ZHIQIANG","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":5243,"user_id":0,"is_guest":1,"slug":"song-shuaihao","display_name":"SONG SHUAIHAO","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":5244,"user_id":0,"is_guest":1,"slug":"wu-jing","display_name":"WU JING","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\/5511","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=5511"}],"version-history":[{"count":3,"href":"https:\/\/www.woodresearch.sk\/cms\/wp-json\/wp\/v2\/posts\/5511\/revisions"}],"predecessor-version":[{"id":5515,"href":"https:\/\/www.woodresearch.sk\/cms\/wp-json\/wp\/v2\/posts\/5511\/revisions\/5515"}],"wp:attachment":[{"href":"https:\/\/www.woodresearch.sk\/cms\/wp-json\/wp\/v2\/media?parent=5511"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.woodresearch.sk\/cms\/wp-json\/wp\/v2\/categories?post=5511"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.woodresearch.sk\/cms\/wp-json\/wp\/v2\/tags?post=5511"},{"taxonomy":"release_year","embeddable":true,"href":"https:\/\/www.woodresearch.sk\/cms\/wp-json\/wp\/v2\/release_year?post=5511"},{"taxonomy":"author","embeddable":true,"href":"https:\/\/www.woodresearch.sk\/cms\/wp-json\/wp\/v2\/ppma_author?post=5511"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
