“…Compared to recently reported fluorescent and transparent films [1,23,42,43,45], our FTW achieved higher mechanical strength, transparency, optical anisotropy, UV-blocking, biodegradability, and hydrophobicity (Fig. 5d, Table S2).…”

“…We note that a general strategy toward fluorescent and transparent wood involves polymer encapsulation with fluorescent carbon dots [23,[42][43][44]; however, the environmental friendliness of such composites is a topic of concern. Being fully derived from wood, FTW films can biodegrade naturally, at the end of their life cycle, with no negative environmental consequences (Fig.…”

“…5 The porous structure of the cellulose framework inside wood has the potential for functional modification, which is expected to replace mainstream transparent materials in the future. Currently, transparent wood has been developed with various special functions such as ultraviolet ray shielding, 6 fluorescent decoration, 7,8 and photoresponsive luminescence characteristics. 9 Reactive dyes are artificially synthesized reactive watersoluble dyes, in which the active groups within the molecules can react with hydroxyl groups on wooden material fibers, forming covalent bonds.…”

In this work, sodium chlorite method was used to remove lignin in basswood and then the wood was dyed with reactive red X-3B dye. Finally, ultraviolet curing resins with a refractive index similar to cellulose were vacuum-impregnated into the wood to obtain red transparent wood (RTW). Nowadays, transparent wood can be given color by various means and has a wide range of application prospects in the field of transparent wood decoration, but the color embodiment is relatively single. The aim was to develop a low-priced, easy-to-use process for the preparation of colored transparent wood with a sound color system. Transparent wood with colors will have more decorative and commercial value. The chemical composition, microscopic morphology, mechanical properties, and optical properties of dyed transparent wood were examined and analyzed. The results of the chemical composition analysis showed that after delignified treatment, the wood lost a large amount of lignin. After the dyeing treatment, the content of cellulose, hemicellulose, and lignin was slightly lost, and reactive dye groups appeared in the wood. Infrared spectra of transparent samples showed that the resin was successfully impregnated into the wood. The microscopic morphology analysis results showed that a small amount of dye molecules aggregated on the cell walls after dyeing treatment, and the resin was impregnated into the porous cellulose skeleton of the wood, filling the wood pores. The analysis of mechanical properties showed that the maximum tensile strength of dyed transparent wood reached 122.31 MPa, which was a higher resistance to tensile force compared to raw wood (with a maximum tensile strength of 97.56 MPa); the elongation at break reached 6.26%, which had better toughness compared to log (4.04%). Optical performance analysis showed that the transmittance of dyed transparent wood reached 81%, and dyeing did not change the transmittance of transparent wood. In addition, after undergoing yellowing resistance experiments, the color difference change of dyed transparent wood was much smaller than that of transparent wood.

“…Lastly, the low density and excellent ability to regulate temperature and humidity from a bamboo template further position it as a promising alternative to conventional glass. Transparent bamboo has been explored in a limited number of studies [ 15 , 16 ], and its transparency is attributed to impregnated organic polymers. Among the various types of organic polymers, EP and PMMA are the most commonly used, owing to their superior optical and mechanical properties.…”

Silica glass, known for its brittleness, weight, and non-biodegradable nature, faces challenges in finding suitable alternatives. Transparent wood, made by infusing polymers into wood, shows promise but is hindered by limited availability of wood in China and fire risks associated with its use. This study explores the potential of utilizing bamboo, which has a shorter growth cycle, as a valuable resource for developing flame-retardant, smoke-suppressing, and superhydrophobic transparent bamboo. A 3-layered flame-retardant barrier, composed of a top silane layer, an intermediate layer of SiO 2 formed through hydrolysis-condensation of Na 2 SiO 3 on the surface, and an inner layer of Na 2 SiO 3 , has been confirmed to be effective in reducing heat release, slowing flame spread, and inhibiting the release of combustible volatiles, toxic smoke, and CO. Compared to natural bamboo and other congeneric transparent products, the transparent bamboo displays remarkable superiority, with the majority of parameters being notably lower by an entire order of magnitude. It achieves a long ignition time of 116 s, low total heat release (0.7 MJ/m 2 ), low total smoke production (0.063 m 2 ), and low peak CO concentration (0.008 kg/kg). Moreover, when used as a substrate for perovskite solar cells, the transparent bamboo displays the potential to act as a light management layer, leading to a marked efficiency enhancement of 15.29%. The excellent features of transparent bamboo make it an enticing choice for future advancements in flame-retardant glasses and optical devices.
