“…FT-IR spectra ( Figure 2 d) show peaks of the HTB sample at 1617 cm −1 (C=C, stretching vibration) [ 16 , 22 , 23 ], 1508 cm −1 (skeleton vibration) [ 18 ], and 1401 cm −1 (C–H, symmetric deformed vibration) [ 24 ], based on comparison with a DB sample, suggesting that lignin and phenol extraction occurred during delignification treatment. A decline in the peak of 1737 cm −1 (hemicellulose of acetyl groups, C=O, stretching vibration) illustrates that hemicellulose was degraded during the delignified treatment.…”

Energy storage materials to modulate indoor microclimates are needed to improve energy efficiency and for human comfort. Of these, phase-change material (PCM) is considered a very useful material because of its excellent latent heat energy storage. For application, some synthetic porous materials for supporting PCM are usually not friendly enough for people and housing environments due to their non-degradation characteristics. Hence, to develop an eco-friendly porous material is needed in order to encapsulate PCM composites that are always expected in indoor applications. In this work, heat-treated bamboo bricks were delignified to provide a delignified bamboo (DB) matrix. A phase-change composite was then fabricated by impregnating DB with polyethylene glycol (PEG) polymer. Impregnation was carried out under wet conditions to ensure the regular arrangement of the DB structure so as to achieve dimensional stability. The final DB/PEG composite was investigated for dimensional stability, load rate, latent heat, and phase-change temperature. Results showed that the DB matrix could be easily impregnated with PEG polymer under wet conditions, and the DB/PEG composite was found to have high enthalpy and a large phase-change temperature interval. Moreover, the composite was found to be a good regulator of indoor temperature and a stable dimension with a snow-white appearance. In summary, this DB/PEG composite is an energy storage material with the potential to modulate ambient indoor temperature and reduce building energy consumption.

“…Namely, the heat treatment positively contributed to the antifungal property of the bamboo [ 27 ]. For instance, the infection ratio of the treated bamboo increased to 100% in 16 days after the treatment temperature was set at 160 degrees C. When the treatment temperature increased to 180 degrees C, the treated bamboo specimens exhibited an excellent antifungal property in comparison to that of the control [ 28 ]. During the heat treatment process, the internal nutrients of the bamboo, such as the polysaccharides and starch, were further reduced as the thermal modification temperature increased [ 29 ].…”

Bamboo, as a potential alternative to biomass materials, has gained more attention from the bamboo manufacturing industry in China. However, the drawbacks, such as the dimensional instability, and low antifungal and hydrophilic properties of bamboo, inhibit its application and shorten its service life. The objective of this work was to analyze the change in chemical components and fungal resistance of moso bamboo with heat treatment. For this objective, moso bamboo specimens were thermally modified in an oven at different temperatures for a fixed duration. The results showed that the parenchymal cells distorted and deformed in comparison to the control after thermal modification. After thermal modification in an oven, the crystallinity index increased from 39% to 53%. Owing to the thermal modification, the hemicellulose and cellulose relative content decreased, as confirmed by FTIR and XPS analysis. Thus, the dimensional stability and antifungal properties of the thermally modified bamboo specimens improved.

Those colorful and rich categories of yarns and fabrics are mostly completed by multi-color dyes.…”
