“…According to the nature of the monomer used, polymerisation can take place either in the cell lumens, in the cell wall or in both (Mathias and Wright 1989;Schneider 1995;Cleland et al 2009). Impregnation of polyglycerol methacrylate obtained from renewable agricultural by-products followed by in situ polymerisation initiated by free radical initiator, was described as an attractive alternative to conventional wood preservation procedures using broadly active biocides (Soulounganga et al 2004). Polymerisation can be initiated by different means using either thermal free radical initiator or gamma radiation.…”

Key message Increasing environmental pressures appearing over the last few years have led to important changes in the field of wood protection. In this context, new technologies, based either on thermal or chemical modifications, suggest increasing interest in prospect of programmed ban of biocide products.• Context The evolution of the regulations on the use of biocide products has led to important changes in the field of wood preservation, leading to an increasing interest for non-biocide treatments like thermal or chemical modifications to face to the programmed ban of biocide products.• Aims The paper reviews the different non-biocide alternatives developed currently on an industrial scale, highlighting their main characteristics and applications.• Results Different treatments have been developed on an industrial scale involving mainly thermal modifications and acetylation, furfurylation and DMDHEU constituting already available solutions.• Conclusion Different non-biocide alternatives already exist and will become more important in the next decades due to the increasing legislative pressure driven by environmental considerations.

“…All methods have some disadvantages (leaching or evaporation of the reactants, changing the color and appearance, etc.) (Soulounganga et al 2004;Habu et al 2006;Brischke et al 2007;Inoue et al 2008;Marcos et al 2009;Manríquez and Moraes 2010). A recent development is the combination of wood with polymers leading to improvements of its mechanical properties (Ibach and Rowell 2001) and/or its dimensional stability by in-situ formation of polymer from monomers within wood pores (Basyal et al 2004).…”

Improvement of dimensional stability of wood via combination treatment: swelling with maleic anhydride and grafting with glycidyl methacrylate and methyl methacrylate

A novel two-step combined treatment of poplar wood was developed to improve its dimensional stability. Maleic anhydride (MAN) was first employed to swell and bond to the wood cell wall, and then mixed monomers of glycidyl methacrylate/methyl methacrylate (GMA/MMA) were grafted to the cell wall through the chemical reaction with MAN within the wood cell lumen. The results of scanning electron microscopy and energy dispersive X-ray apparatus (SEM-EDX) and Fourier transform infrared spectroscopy (FTIR) analyses indicate that MAN penetrated and chemically bonded to the cell wall causing 9% volume swelling, and the copolymer from GMA/MMA monomers was grafted onto the wood cell wall, resulting in the improved interfacial compatibility between the polymer and wood matrix. The dimensional stability of poplar wood modified by the combined two-step treatment was remarkably improved compared with that of untreated poplar wood. The combination treatment of wood employed in this study proved to be more effective for improving the dimensional stability than treatment with PEG-1000 aqueous solution with 30% concentration.

“…19,20 All of these concerns have a great impact on the application and popularity of WPCs. Although some studies have been done to address these problems, on the basis of the utilization of various coupling agents and formaldehyde scavengers, [21][22][23][24][25][26] the problems have not been completely resolved, and further efforts are still needed in this field.…”

Wood-polymer composites (WPCs) were prepared from poplar wood (P. ussuriensis Komarov) in a two-step procedure. Maleic anhydride (MAN) was first dissolved in acetone and impregnated into wood; this was followed by a heat process; and then, glycidyl methacrylate (GMA) and styrene (St) were further impregnated into the MAN-treated wood, followed by a second thermal treatment. Finally, the novel WPC was fabricated. The reactions occurring in the WPC, the aggregation of the resulting polymers, and their interaction with the wood substrate were analyzed by scanning electron microscopy, Fourier transform infrared spectroscopy, X-ray diffraction, and dynamic mechanical analysis. The performance of WPC was also evaluated in terms of the mechanical properties and durability, which were then correlated with the structural analysis of the WPC. The test results show that MAN and GMA/ St chemically reacted with the wood cell walls in sequence, and the quantity of hydroxyl groups in the wood cell walls was evidently reduced. Meanwhile, St copolymerized with GMA or MAN, and the resulting polymers mainly filled in the wood cell lumen in an amorphous form, tightly contacting the wood cell walls without noticeable gaps. As a result, the mechanical properties, decay resistance, and dimensional stability of the WPC were remarkably improved over those of the untreated wood, and its glass-transition temperature also increased.
