In this research, fully environment-friendly, sustainable and biodegradable ‘green’ composites were fabricated. A novel material comprised of microfibrillated cellulose and laponite clay with different inorganic/organic ratios (m/m) was prepared. The composites were characterized by tensile, bending and water absorption tests as well as dynamic mechanical analysis. The morphologies of these nanocomposites...
Nanocrystalline cellulose (NCC), prepared by acidic hydrolysis of microcrystalline cellulose (MCC), was oxidized with the TEMPO–NaBr–NaOCl system and subjected to ultrasonic treatment. Carboxylated NCC (C.NCC) having high carboxylate content (%) was thereby produced directly. Modified NCC was then incorporated into gliadin matrices and the effect of their loading content (1, 2.5, 5, 7.5 and...
Many load-bearing applications of hydrogels, such as human tissue replacements, require extremely high stiffness, strength and fracture energy, which are rarely achieved simultaneously. Here, we report cellulose nanofiber-based nanocomposite hydrogels, exhibiting highly increased stretchability but with no sacrifice in stiffness when compared with pure rehydrated cellulose nanofiber networks. The...
