Poplar wood, which is primarily used to manufacture wood-based panels, furniture, and paper, is a fast-growing plantation wood that is produced with high yields; however, its poor mechanical properties and perishability limit its application. Herein, we propose a method that enables sil-ica-alumina sol to penetrate wood smoothly. In this method, silica-alumina sol is added into an ether polymer by blending, and the mixture is completely stirred until hybridization. The ether polymer introduces the silica-alumina sol into wood via pressure impregnation. Poplar wood treated with this hybrid mate...
