“…Examples include the use of metal nanoparticles to increase thermal conductivity, to enhance panel pressing (Khojier et al 2010, Drelish 2013, Saber et al 2013, the use of nano-copper or silver particles to improve resistance to microbial attack (Akhtari et al 2013, Maresi et al 2013, Taghiyari et al 2014a) and the addition of nano-wollastonite to enhance fire resistance (Ozdemir and Tutus 2013, Taghiyari et al 2013a, 2014. Nano particles appear to produce a series of unique changes in material properties not produced with larger particles of the same material (Li 2012).…”

The effects of wollastonite fibers on the physical and mechanical properties of medium-density fiberboards composed of wood fibers with up to 10 % camel-thorn chips were studied. Approximately 30 % of the wollastonite fibers were less than 100 nm while the remainder were less than 1 μm. Wollastonite fibers significantly improved most of the physical and mechanical properties while addition of camel-thorn produced more variable effects on panel properties. Up to 10 % camel-thorn could be added to panels without negative effects. A combination of 10% camel-thorn and 5% wollastonite fibers produced panels with the best properties.

“…The fire-retardant properties of nano-wollastonite, as a silicate mineral (CaSiO3), have been reported as promising when used in solid woods (Haghighi et al 2014) and wood-composite materials (Taghiyari et al 2013b). Wollastonite nanofibers have also been reported to improve the biological resistance against the wood-deteriorating fungus Trametes versicolor in trees (Karimi et al 2013;Maresi et al 2013;Taghiyari et al 2014).…”

The improving effect of an increase in the thermal conductivity caused by nano-wollastonite (NW) on the physical and mechanical properties of medium-density fiberboard (MDF) was studied. Nanowollastonite was applied at 2, 4, 6, and 8 g/kg, based on the dry weight of wood-chips, and compared with control specimens. The size range of wollastonite nanofibers was 30 to 110 nm. The results show that NW significantly (p < 0.05) increased thermal conductivity. The increased thermal conductivity resulted in a better curing of the resin; consequently, mechanical properties were improved significantly. Furthermore, the formation of bonds between wood fibers and wollastonite contributed to fortifying the MDF. It was concluded that a NW content of 2 g/kg did not significantly improve the overall properties and therefore cannot be recommended to industry. Because the properties of NW-6 and NW-8 were significantly similar, a NW-content of 6 g/kg can be recommended to industry to significantly (p < 0.05) improve the properties of MDF panels.

“…Notwithstanding, several authors investigated the effect of inorganic nanostructured materials on wood or bamboo [25][26][27][28]. In this work we propose to tailor the effects of densification by introducing selected nanostructured materials in the structure of giant reed, i.e., silicon carbide (SiC) and graphene oxide (GO).…”

Strengthening of Wood-like Materials via Densification and Nanoparticle Intercalation

Recently, several chemical and physical treatments were developed to improve different properties of wood. Such treatments are applicable to many types of cellulose-based materials. Densification leads the group in terms of mechanical results and comprises a chemical treatment followed by a thermo-compression stage. First, chemicals selectively etch the matrix of lignin and hemicellulose. Then, thermo-compression increases the packing density of cellulose microfibrils boosting mechanical performance. In this paper, in comparison with the state-of-the-art for wood treatments we introduce an additional nano-reinforcemeent on densified giant reed to further improve the mechanical performance. The modified nanocomposite materials are stiffer, stronger, tougher and show higher fire resistance. After the addition of nanoparticles, no relevant structural modification is induced as they are located in the gaps between cellulose microfibrils. Their peculiar positioning could increase the interfacial adhesion energy and improve the stress transfer between cellulose microfibrils. The presented process stands as a viable solution to introduce nanoparticles as new functionalities into cellulose-based natural materials.
