“…Cellulose has a high degree of polymerization and crystallinity due to the chemical reactivity of the three hydroxyl groups (one primary and two secondary) present in each repeating cellobiose unit of cellulose, which keeps the fiber molecules tightly packed in parallel. In addition to being durable, cellulose fibers can withstand temperatures of up to 250 • C before decomposing [22,23]. To ensure sterility and purity, the cotton fabric utilized in this study was bought as medical bandaging.…”

Lung supportive devices (LSDs) have been extensively utilized in treating patients diagnosed with various respiratory disorders. However, these devices can cause moisture depletion in the upper airway by interfering with the natural lubrication and air conditioning process. To remedy this, current technologies implement heated humidification processes, which are bulky, costly, and nonfriendly. However, it has been demonstrated that in a breath cycle, the amount of water vapor in the exhaled air is of a similar quantity to the amount needed to humidify the inhaled air. This research proposes to trap the moisture from exhaled air and reuse it during inhalation by developing a state-of-the-art hydrophilic/hydrophobic polymer tuned to deliver this purpose. Using the atom transfer radical polymerization (ATRP) method, a substrate was successfully created by incorporating poly (N-isopropyl acrylamide) (PNIPAM) onto cotton. The fabricated material exhibited a water vapor release rate of 24.2 ± 1.054%/min at 32 °C, indicating its ability to humidify the inhaled air effectively. These findings highlight the potential of the developed material as a promising solution for applications requiring rapid moisture recovery.

“…The first weight loss at 150 °C was due to dehydration, indicating absorbed water in the film is approximately 5 wt%. The second weight-loss began near 225 °C, indicating the onset degradation associated with the decomposition of a thermally sensitive carboxyl group, which is prone to decarbonization on the surface of the CNF film [35][36][37]. The followed third weight loss was due to the decomposition of secondary alcohol in the cellulose chain.…”

Conventionally, the photon sieve (PS) was made of chrome-coated fused silica and quartz plates. However, fused silica and quartz plates have a size limitation due to their weight and fragility. A membrane PS is attractive since it is lightweight, large size, flexibility and deployable. This paper demonstrates the new concept of membrane PS based on cellulose nanofiber (CNF). The CNF-based PS (CNF-PS) is transparent, flexible, lightweight, and has high strength and toughness. This study highlights the PS fabrication on a CNF film using a micro-nano structure molding technique and its structural stability in an external environmental change. For the first time in literature, through a high vacuum (5 × 10 -8 Torr) environment test, it was shown that CNF has emerged as a promising optical material. Furthermore, the prepared CNF-PS exhibited high beam quality. This study explained the complete research strategy from the isolation of cellulose nanofibers to its PS application. The new concept of CNF-PS will accelerate its broad application to thin and compact photonic devices.
