Biodegradable and Reusable Cellulose-Based Nanofiber Membrane Preparation for Mask Filter by Electrospinning

“…The smallest average pore size of 0.90 µm was achieved when the LiCl concentration was 1 wt%, which confirms that the finest and most uniform fibers would form filtration members with the smallest pore size. Under this condition, more fibers can be piled up in the same space, the pore size of the fiber decreases with the increase of density, which is most suitable to intercept fine particles and achieve higher filtration efficiency [19].…”

Employing Cellulose Nanofiber-Based Hydrogels for Burn Dressing

“…One advantage of CNF is that its surface can be easily modified due to the abundant -OH structural moieties. Surface modification can increase material performance in various ways [ 21 , 22 , 23 ]. For example, cationic CNF created with quaternary ammonium compounds produce materials with antimicrobial properties, which have many potential applications in the biomedical and pharmaceutical fields.…”

Development of Cellulose Aerogel as a New Material for the Reduction of Harmful Substances in Cigarette Smoke

“…This suggests that the prepared lter samples have less porosity compared to the typical (conventional) lter for cigarettes (Cellulose Acetate). In general, it was observed that with increasing the concentration of CNF and the amount of PAC, the average pore diameter and pore volume decrease due to the compaction that results in higher density cigarette lters [21,24,25]. -----------------8.81 0.031…”

“…The small pore diameter in the fabricated lters reduces the air ow rate, which allows the smoke to interact intimately with the lter material. On the contrary, the large pore diameter of the CAF provides little resistance to air ow, which leads to a drop in pressure [23,25].…”
