“…In this experiment, water was used as the reaction medium, and the long-term exposure of a high concentration of ozone had a significant impact on the aldehydes in the sample, resulting in a decline in their contents. The sodium bicarbonate and ozone treatments presented a good removal ability of the VOC ester compounds; sodium bicarbonate can promote the hydrolysis of esters [23,24], and it has been found that ozone has a good effect on esters in the treatment of municipal sewage [49].…”

“…Additionally, researchers have found that treating cannabis leaves with sodium bicarbonate could inhibit their VOC acidity and reduce aldehyde emissions [22]. However, the treatment of wood with sodium bicarbonate will lead to the increase of hydroxyl on the surface of wood [23], which can easily decompose hemicellulose and lignin, thereby damaging the structure of wood [24] and affecting its use. In this experiment, weakly alkaline sodium bicarbonate was used to treat the radiata pine for reducing VOCs, and exhibited less impact on the performance of samples while removing VOCs.…”

Volatile organic compounds (VOCs) in wood furniture are an important factor that affects indoor air quality. In this study, radiata pine (Pinus radiata D. Don) was treated with sodium bicarbonate and ozone aqueous solution to reduce the VOC contents without sacrificing mechanical properties. The VOCs of radiata pine were identified by gas chromatography-mass spectrometry (GC-MS), and the functional group changes of wood samples were characterized by Fourier-transform infrared spectroscopy (FTIR). The results showed that the main VOCs of radiata pine include alkenes, aldehydes, and esters. The sodium bicarbonate and ozone treatments almost eliminated the VOC contents of radiata pine. The two treatments mentioned above had little effect on compressive strength and surface color of radiata pine.

“…Thermogravimetric (TG) analysis was carried out with a TG 209 analysis system for thermal weight loss analysis in an N 2 or air atmosphere at a heating rate of 10°C·min -1 from an ambient temperature to 770°C. The abrasion resistance of the MgAl-LDH coating on the bamboo surface was tested by the method in the literature [15]; as shown in Figure 1, MgAl-LB (longitudinal × tangential × radial: 10 × 10 × 3 mm 3 ) was rubbed with a 1500-mesh sandpaper at a pressure of 1000 Pa. The water contact angle of the sample surfaces was measured at every 30 cm of abrasion length (water contact angle of not less than 5 different positions).…”

In recent years, bamboo has been widely used for building materials and household goods. However, bamboo is flammable, so a flame-retardant treatment for bamboo is urgently needed. In this work, nano MgAl-layered double hydroxide (MgAl-LDH) coated on bamboo, which was called MgAl-LB, was synthesized by an in situ one-step method. To determine the optimal in situ time, the effects of different reaction times on LDH growth on the bamboo surface and the flame retardancy of the MgAl-LBs were investigated. The SEM observations show that LDH growth on the surface of bamboo was basically saturated when the in situ reaction time was 24 h. Abrasion experiments show that MgAl-LDH coating has good abrasion resistance. The fire performance of the MgAl-LBs was evaluated by cone calorimeter tests, which indicated that the THR and TSP of the MgAl-LBs were significantly lower than those of untreated bamboo. Taking into account the energy consumption problem, determining the reaction time of 24 h is the optimal reaction time. Compared with untreated bamboo, the THR and TSP of MgAl-LB prepared at 24 h decreased by 33.3% and 88.9%, respectively.

“…As a sustainable and natural material, wood provides many special benefits, such as esthetic appeal, mechanical strength, thermal isolation, and humidity controllability (Jia et al 2018;Liu et al 2019). Therefore, it has a wide range of applications including decoration, architecture, and even railway construction (Dong et al 2017;Montanari et al 2019;Wang et al 2014).…”

In this work, a novel waterborne hyperbranched polyacrylate (HBPA) dispersed organo-montmorillonite (OMMT) emulsion was synthesized and used for the treatment of wood in a vacuum environment in order to enhance the physical and mechanical properties of the wood. The sapwood of Cathay poplar (Populus cathayana Rehd.) and Radiata pine (Pinus radiata D.Don) were used as the samples for experimentation. The results showed that the physical and mechanical properties of the wood improved significantly due to the successful penetration of the OMMT and HBPA into the wood cell wall. From it was also observed that OMET completely exfoliated from the HBPA matrix and formed a hydrophobic film covering on the inside walls of the cell lumen. Further, it was observed that the poplar sample displayed better mechanical properties than the pine sample because the pine has a more compact structure when compared to poplar and contains rosin. Furthermore, it was also observed that the mechanical properties of the modified wood sample gradually improved with an increase in the concentration of the emulsion. However, excessive concentration (>4 wt%) did not lead to further improvement.
