“…Plant-based composites received much attention worldwide due to their eco-friendliness and degradability. , The development of plant-based self-bonding composites has gained momentum in recent years, largely because no additional adhesives are involved, and thus no potential risks of the release of toxic or harmful volatiles occur. One of the pressing issues facing conventional fiberboards or particleboards bonded with formaldehyde adhesives is the hardly unavoidable release of formaldehyde, which threatens human health.…”

Parenchyma cells (PCs) and bamboo fibers (BFs) are the main component units of natural bamboo. However, PCs have long been discarded as waste during the industrial processing and utilization of bamboo, i.e., papermaking, textile, and composites, because of their inferior mechanical properties and higher hygroscopicity compared to the BFs. Here, we proposed to mechanically separate PCs from BFs and subsequently recombine them to generate formaldehyde-free bamboo self-bonding composites (BSCs), which physical–mechanical properties were tuned for the first time by adjusting the PC content. The PC effects were examined on the formation and material properties of the BSCs in terms of microstructure and physical–mechanical properties. Microscopic observation revealed that PCs with a high cavity-to-cell wall ratio were more likely to deform and bridge adjacent particles during hot pressing, thus forming a dense interlocking structure with heat-sealed points between the BFs. The inclusion of the PCs into the BSCs led to much lower water absorption and thickness swelling than without the PCs. The BSCs containing 40% BFs and 60% PCs had a thickness swelling of 13.3%, fulfilling the performance requirements of commercial high-density fiberboards used in humid environments. The 40% BFs/60% PCs made BSCs also exhibited the highest flexural strength, flexural modulus, and internal bonding strength, increasing by 99.8, 60.8, and 189.9%, respectively, compared with sole BF-made BSCs. The eco-friendly and formaldehyde-free BSCs with tunable properties are promising for use in furniture, packaging, and interior decorations.

“…With the development of social and technology, more attention has been paid to environmental protection. Natural fibers, including ramie fiber and coir pith, have good environmental compatibility and are of great significance in the development of various industries, including textiles, nanobiocomposites, aerogels, and so on. − Ramie, a perennial herb, is a valuable bast fiber crop. Ramie has historically been a crucial natural textile material for the Chinese and is commonly referred to as “Chinese grass”. , Ramie fiber is slender, tough, and possesses a tubular chamber in the center.…”
