Novel luminescent hierarchical porous hydrogels with a three-dimensional interconnected network structure from feather keratin crosslinking reaction

Abstract

Six novel keratin-based fluorescent hierarchical porous hydrogels, pure keratin (FK), keratin-seaweed (FK-SP), keratin-chitosan (FK-CS), and keratin-rhodamine B (FK-Rh B) with three-dimensional (3D) interconnected network structure have been prepared via a...

Keratin-derived sorbents for efficient removal of copper ions from aqueous solutions

“…21 Keratin is biocompatible and biodegradable, making it highly promising in the synthesis of polymer materials. 22 This is mainly due to the side chains of the amino acids in the keratin peptides possessing unique chemical configurations, bonding capabilities, charges, and reactivities. Therefore these side chains can be modified through various chemical treatments to result in more functional groups on their surface enhancing their ability to remove pollutants, which serves as a critical factor in the adsorption process.…”
