“…In a typical synthesis process [29,36], a methanol solution of sodium hydroxide (NaOH, 0.12 M) was added slowly to a methanol solution of Zn(CH 3 COO) 2 •2H 2 O (Zn(Ac) 2 , 0.04 M) with a volume ratio of 1:1. Subsequently, the resulting mixed solution was stirred for 30 min at 60 • C using a magnetic stirrer (DF-101S, Yuhua Instrument Co. Ltd., Gongyi, China), until a homogeneous and stable colloid solution formed.…”

“…The original bamboo ( Figure 2B(a)), had an absorption peak at 1036 cm −1 , belonging to skeletal vibration of the C-O-C from the pyranose ring [38]. The absorption bands at 1742 cm −1 and 1423 cm −1 could be attributed to the C=O stretching vibration and C-H asymmetric stretching vibration, respectively [36]. Compared with the original bamboo, the FTIR spectrum of ZnO/bamboo showed a distinct absorption peak at 460 cm −1 , as shown in Figure 2B(b), which could be assigned to the stretching vibration of the Zn-O groups [29].…”

Poor mildew resistance has limited the application of bamboo materials. In this work, ZnO/PMHS coatings were fabricated on bamboo timber surfaces by hydrothermal synthesis method and hydrophobic modification with poly(methylhydrogen)siloxane (PMHS). The surface chemical characteristics and microstructure of the bamboo before and after modification were investigated using Fourier transform infrared spectroscopy, scanning electron microscopy, energy dispersive X-ray spectroscopy, X-ray diffraction, and water contact angle (WCA). The morphology results indicated that ZnO on the surface of bamboo forms flower-like aggregations. The WCA of ZnO/bamboo increased from 65° to 142° after PMHS hydrophobic modification, indicating that the hydrophobicity of bamboo was significantly improved. The original bamboo had poor anti-mildew properties when exposed to Trichoderma viride, Aspergillus niger, and Penicillium citrinum. After depositing ZnO onto the surface of the bamboo, the anti-mildew properties were significantly improved. Furthermore, it was found that after PMHS hydrophobic modification, ZnO/bamboo had excellent anti-mildew properties when exposed to the three mold hyphae, which indicated that PMHS hydrophobic modification had a synergistic effect on the anti-mildew properties of bamboo with a ZnO coating.

A facile method for fabricating the superhydrophobic bamboo timber based on an anatase TiO 2 film for acid rain protection and flame retardancy is described in the present work. The bamboo timber with the maximal water contact angle of 154° has been prepared by the hydrothermal deposition of anatase TiO 2 nanoparticles and further modified with octadecyltrichlorosilane (OTS). The geometric microstructure of anatase TiO 2 nanoparticles and chemical composition of the superhydrophobic coating were analyzed by scanning electron microscope (SEM), energy dispersive X-ray spectroscopy (EDX), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR) and thermogravimetric analysis (TGA). The wetting behavior of bamboo timber samples was investigated by water contact angle (WCA) measurement.The results indicated that the strong hydrogen bonds were formed between the amorphous TiO 2 and the hydroxide radicals of bamboo timber surface, and the strong interaction contributed to the heat stability enhancement of the TiO 2 /bamboo timber composites. Moreover, diverse performances of superhydrophobic bamboo timber have been evaluated as well. The treated bamboo timber exhibited the outstanding superhydrophobicity, excellent waterproofing durability, acid rain resistance, and flame retardancy, offering a potential opportunity to accelerate the large-scale production of superhydrophobic woody material for new industrial applications.

Since formaldehyde is considered to be a potential risk for human health, its emission must be eliminated in an effective way. In this study, anatase TiO 2 particles with silver nanoparticles were doped on wood substrates through a two-step method and used as a photo-catalyst for formaldehyde degradation. The effect of Ag dopant on the formaldehyde degradation of the TiO 2 -treated wood was investigated. The results showed that the formaldehyde response of the TiO 2 film was drastically improved by doping with Ag nanoparticles under visible-light irradiation. In this heterostructured system, because the Fermi level of Ag was lower than the conduction band of TiO 2 , Ag nanoparticles can act as electron scavenging centers to cause electron and hole pair separation, leading to enhanced photo-catalytic activity of TiO 2 .
