“…Metallic nanoparticles have been used to protect wood against biodegradation agents and weathering since decades ago [ 197 , 218 , 219 ]. Nanoparticles offer better characteristics than their bulk form, mainly because of their reduced size that leads to high specific surface area-to-volume ratio, uniform size distribution and good stability.…”

Wood-based industry is one of the main drivers of economic growth in Malaysia. Forest being the source of various lignocellulosic materials has many untapped potentials that could be exploited to produce sustainable and biodegradable nanosized material that possesses very interesting features for use in wood-based industry itself or across many different application fields. Wood-based products sector could also utilise various readily available nanomaterials to enhance the performance of existing products or to create new value added products from the forest. This review highlights recent developments in nanotechnology application in the wood-based products industry.

“…[1][2][3][4][5][6] The idea of protecting solid wood, and wood-and cellulosebased materials against different physical and chemical damages and attacks of living micro-organisms is as old as human civilizations. [7][8][9][10][11] Over time, numerous methods and materials have been examined and developed. Some methods involved changing the pathway of pyrolysis of wood.…”

“…6,[18][19][20][21][22] Wood-based materials and composites are no exception. 23,24 Different nano-metals and nanominerals were utilized to improve the heat-transfer property in solid wood species and wood composite mats; they were also used to improve biological resistance against different deteriorating fungi, 7,9,[25][26][27][28] to decrease hot-press time as a costly bottle-neck in nearly all wood-composite manufacturing factories, and to increase thermal conductivity in solid wood and composite mats. 29 In this connection, wollastonite is a calcium inosilicate mineral (CaSiO 3 ), which contains small amounts of iron, magnesium, and manganese substituting for calcium, that has been proved as nontoxic and harmless for both human health and wildlife.…”

Improving fire retardancy of medium density fiberboard by nano‐wollastonite

et al. 2020

Summary The improving effects of addition of nano‐wollastonite on some fire properties of medium‐density fiberboard (MDF) were studied in this work. Nano‐wollastonite was added at four levels (2%, 4%, 6%, and 8%). The size range of at least 70% of nano‐wollastonite particles were 30 to 110 nm. The results showed statistically significant improving effect of nano‐wollastonite on time to onset of ignition. The improving effect was primarily attributed to an increase in thermal conductivity of board containing nano‐wollastonite. This increase in turn resulted in better curing of resin, and a higher integrity of fibers thereof. Moreover, nano‐particles provided a surface with reduced combustibility and therefore, penetration of fire to the inner layers of boards was delayed, thus improving fire properties. High and significant correlations were found between thermal conductivity coefficients of boards with different fire properties. It was concluded that for applications where fire properties are of prime importance, nano‐wollastonite content of 8% can be recommended. Moreover, further studies are needed to compare and standardize the results obtained from the apparatus used here with those obtained from internationally recognized apparatuses like cone calorimeter.

“…Therefore, in the present project, wollastonite was used to find out if it can have hindering effects on the growth of fungi on cotton textiles which are constantly used in paintings of museums. In order to increase effectiveness of wollastonite and to benefit from the advantages of materials at nanoscale [12][13][14][15][16], wollastonite nanosuspension with four concentrations were used to impregnate cotton textile specimens. Specimens were then exposed to Aspergillus niger [17], as a dominant fungus species in Moghadam Museum of University of Tehran.…”

Fluid Flow in Cotton Textile: Effects of Wollastonite Nanosuspension and Aspergillus Niger Fungus

et al. 2019

Aspergillus niger is a common contaminant in food industry, laboratories, and also a potential threat to biological works of art in museums. Cotton textiles have frequently been used in museums for canvas paintings. In the present project, the effect of Aspergillus niger on fluid flow rate of nanowollastonite-impregnated cotton textile specimens was investigated. Cotton specimens were impregnated with nanowollastonite (NW) suspension at four concentrations of 10%, 20%, 30%, and 40% to be further compared with control specimens. Results showed that fluid flow in cotton textile was as high as 361.3 cm3·s−1 due to its high porous structure and very low compactness of fibers (low density). Impregnation with NW did not have a significant effect on fluid flow in cotton textile. Exposure to Aspergillus niger increased fluid flow in control specimens as a result of deterioration of cotton fibers. Exposure of NW-impregnated specimens at concentrations more than 20% to Aspergillus niger did not have any significant effect on fluid flow. In control specimens, fungus mycelium penetrated deep into the texture of textile. However, in NW-impregnated specimens, the fungus could not penetrate into the texture and deteriorate the specimens. It was concluded that NW can be recommended for textile industry and also works of art as they protect cotton textiles against Aspergillus niger while, do not diminishi its dying and paintability properties.
