5 days ago · The P-XRD spectrum of the BC film confirmed its crystallinity as it shows typical peaks at 2θ = 14.4°, 16.8°, and 22.7° corresponding to (100), (010), and (110) planes of cellulose I α (Fig ...
Sep 8, 2024 · To better demonstrate and explain the curing and bonding mechanism of the newly prepared pure natural biomass adhesive, we conducted separate curing and film-forming experiments on...
Sep 13, 2024 · Our insights into the early nucleation events of cellulose nanocrystals give important information about the growth of cholesteric liq. cryst. phases, esp. for cellulose nanocrystals, and are crucial for prepg. photonics-quality films.
1 day ago · Ethyl cellulose (EC) is one of the most widely used cellulose derivatives. Nevertheless, challenges such as the formation of beaded fibers, low yield, and nonporous internal structure persist in electrospinning, limiting functional improvements and industrial applications. This study invented a groundbreaking high-speed electrospinning technique through sheath liquid assistance to optimize the Taylor cone, dramatically enhancing the yield, morphology, and formation of porous structures of EC ...
Sep 24, 2024 · Owing to the hydrophilic character of cellulose, neat films of cellulose nanomaterials do not exhibit particularly good barrier against water vapor, especially when compared to synthetic fossil-based materials.
5 days ago · In this paper, a transparent film with antibacterial properties and excellent tensile property was prepared utilizing keratin extracted from waste chicken feathers, combined with citric acid-modified cellulose nanocrystals (CNC-CA). The film exhibited an elongation at break of 209%, highlighting its substantial potential for food packaging ...
