Taking the mass ratio of nano-SiO2 mass to the solid content of urea-formaldehyde resin impregnation solution (W), high-temperature (H), and high-temperature time (T) as influencing factors, the effects of impregnation high-temperature heat treatment modification on the physical and mechanical properties of fast-growing poplar were explored. At the same time, the weight loss rate, oven-dry density, dry shrinkage properties, swelling properties, modulus of rupture (MOR), and modulus of elasticity (MOE) of the modified poplar were measured. The research results show that both the weight loss rate and the coefficient of variation of the oven-dry density have a high correlation with the temperature; the high-temperature immersion heat treatment can reduce the dry shrinkage and swelling of poplar, improve the dimensional stability, MOR, and MOE. W is 0\u20131%, H is 160 \u00b0C, and T is 2\u20134 h. The impregnated heat-treated wood has good MOR and MOE. Therefore, the combination of nano-SiO2 and urea-formaldehyde resin impregnation and heat treatment to modify poplar can improve some physical and mechanical properties of fast-growing poplar, expand the use of poplar, increase its added value, and realize high-value utilization.<\/jats:p>","DOI":"10.3390\/ma15207334","type":"journal-article","created":{"date-parts":[[2022,10,20]],"date-time":"2022-10-20T22:49:46Z","timestamp":1666306186000},"page":"7334","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":35,"title":["Effects of High-Temperature Heat Treatment Modification by Impregnation on Physical and Mechanical Properties of Poplar"],"prefix":"10.3390","volume":"15","author":[{"given":"Jixiao","family":"Xue","sequence":"first","affiliation":[{"name":"Co-Innovation Center of Efficient Processing and Utilization of Forest Resources, Nanjing Forestry University, Nanjing 210037, China"},{"name":"College of Furnishings and Industrial Design, Nanjing Forestry University, Nanjing 210037, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wei","family":"Xu","sequence":"additional","affiliation":[{"name":"Co-Innovation Center of Efficient Processing and Utilization of Forest Resources, Nanjing Forestry University, Nanjing 210037, China"},{"name":"College of Furnishings and Industrial Design, Nanjing Forestry University, Nanjing 210037, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jichun","family":"Zhou","sequence":"additional","affiliation":[{"name":"College of Furnishings and Industrial Design, Nanjing Forestry University, Nanjing 210037, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Weiguo","family":"Mao","sequence":"additional","affiliation":[{"name":"College of Furnishings and Industrial Design, Nanjing Forestry University, Nanjing 210037, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shuangshuang","family":"Wu","sequence":"additional","affiliation":[{"name":"College of Furnishings and Industrial Design, Nanjing Forestry University, Nanjing 210037, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,10,20]]},"reference":[{"key":"ref_1","first-page":"223","article-title":"Research Progress of Wood Low Molecular Weight Resin Impregnation Modification and Its Drying","volume":"36","author":"Xu","year":"2022","journal-title":"Mater.
