“…Some studies were performed on wood impregnation modification. Poplar wood through MMA impregnation greatly improved its surface properties; PMMA is contained mainly in the void spaces of the wood Koubaa et al 2012). Through two different chemistry routes, the methacryl groups were inserted into wood cell walls, allowing them to be used as the anchoring points for grafting; various polymers can be inserted into the wood structure (Keplinger et al 2015).…”

The objective of this study was to determine rheological behaviors of maple veneer plastic composite (MVPC) prepared by full cell preparation technology through the use of a rotational rheometer. The results showed that at 25 to 105 °C, the storage modulus G' and loss modulus G'' of the MVPC were apparently higher than that of the control. In the range 105 to 210 °C, the storage modulus G' of the MVPC was basically the same as that of the control, and the loss modulus G'' was slightly higher than that of the control. At 105 °C, the Tanδ curve of the MVPC had an obvious peak, which indicated that the glass transition temperature (Tg) of the MVPC was about 105 °C. The rheological behavior of the MVPC with different impregnation weight gain rates showed that the MVPC with a 55% impregnation weight gain rate had higher G', G'', and Tanδ.

“…Additionally, enhancement of the dimensional stability, reduction of the swelling, an increase in the decay resistance, and alteration of the chemical composition of wood has been found in thermally modified wood Militz and Tjeerdsma 2001;Yildiz 2004a;Temiz et al 2006;Charani et al 2007;Koubaa et al 2011). On the other hand, reduction in strength (MOR, MOE) has been found to occur in thermally modified wood (Bengtsson et al 2002;Yildiz et al 2002;Poncsak et al 2006).…”

The effects of acid copper chromate (ACC) and hydrothermal treatments were determined relative to the hardness, decay resistance, and dimensional stability of poplar wood. Test specimens, prepared from poplar wood (Populus nigra L.), were first heat-treated under saturated steam in a digester and then impregnated with ACC solution and by a long-term (21 days) dipping technique to reach complete saturation. Impregnated specimens were exposed to white-rot fungus (Trametes versicolor) for 14 weeks, using the Kolle flask method. The weight loss and Brinell hardness were determined after impregnation, thermal treatment, and exposure to T. versicolor. The combination of thermal treatment and ACC preservative on the poplar wood showed improved hardness and decay resistance properties of wood, depending on the treatment time and temperature. The highest weight loss (37.78%) was observed for control specimens, and the lowest (3.03%) occurred in 1% ACC-treated specimens. The highest Brinell hardness on a tangential surface was observed in 1% ACC-treated specimens (6.45 kN), and the lowest was noted in the specimens heat-treated at 130 °C and 180 min (0.52 kN).

“…Meanwhile, the polymer could share part of strength for wood, which improves the mechanical properties [11][12] . Many monomers are employed to produce polymer within wood cell lumen such as methyl methacrylate, styrene, vinyl acetate, acrylonitrile and so on [13][14][15][16][17][18][19][20][21][22] . However, these monomers are lowpolar reagents that are hard to react with wood components, leading to poor compatibility between wood and polymer.…”

In order to improve the decay resistance of wood, we propose a novel method by in-situ hybridization of reactive monomers and nano-SiO2 within wood porous structure to modify wood structure and chemical components. Glycidyl methacrylate (GMA), and polyethylene glycol-200 dimethacrylate (PEGDMA) were first mixed and then penetrated into poplar wood cell lumen by vacuum/pressure treatments, followed by in-situ hybridization under an initiation condition. Scanning electron microscopy with energy dispersive X-ray spectroscopy (SEM-EDX) and transmission electron microscopy (TEM) observations described that the polymer-inorganic hybrid nanocomposite filled up cavities and tightly contacted the wood cell wall. Nano-SiO2 particles were uniformly dispersed into the formed polymer within wood pores. Fourier transform infrared spectroscopy (FTIR) analysis suggested that the nano-SiO2 probably chemical bonded to the polymer during the monomer polymerization. The derived wood-based polymer-inorganic hybrid nanocomposite exhibited remarkably improvement in decay resistance over the untreated wood as controls. Such treatment could potentially widen the wood applications with outstanding decay resistance.
