“…After keratin coating, the peaks appeared at 1655 cm −1 and 1542 cm −1 , representing the C = O stretching vibrations related to amide I bonds and N-H bendings of amide II bonds. The successful immobilization of keratin is determined by the presence of these peaks [29].…”

This study offers a new wound dressing by immobilization of amino acid residues on partially carboxymethylated cotton nonwoven fabrics (CM-CN). To improve the absence of capacity to protect the open wound from infection, firstly, a usual cotton nonwoven fabric was chemically modified by utilizing a pad-dry-cure technique including a carboxymethylation procedure. Subsequently, the chicken feather wastes as a natural source were used for the cationization of CM-CN by the same method. Keratin successfully was extracted from chicken feathers using both chemical and enzymatic processes. Physicochemical and biological properties of the prepared samples were evaluated by FTIR, SEM, mechanical properties such as tensile, bending test and wrinkle recovery, biodegradation, permeability (air and water vapor), and MTT assay for cell viability and proliferation. The tensile strength increased to 200%, the air permeability almost doubled, and the greatest cell growth was observed for modified samples. According to the obtained results, enzymatic extraction was influential and the samples coated with enzyme-extracted keratin showed enhanced properties suitable for wound dressing applications.

“…The chicken feathers fiber comprises of 91% keratin, 8% water, and 1% lipids [9]. Chicken feather fibers are used in microbial corrosion-resistant application and in production of absorbent sponges and composite sponges for cleaning lenses and highly polished surfaces because of the absorbance nature of keratin [10]. Studies have revealed that chicken feather fiber-reinforced composites showed good mechanical, acoustic, and thermal properties because of their chemical composition, low density, and morphological structure [9].…”

“…The fiber is semi-crystalline and shows a lower degree of crystallinity than mulberry silk [9]. Amongst the silk fiber from various species, dragline silk is one of the strongest silks with a tensile strength of 1.1 GPa that can be compared to high tensile steel (1.5 GPa) [10].…”

In spite of the fact that a prodigious portion of petroleum covers multitudinous products in the commercial world, its nonbiodegradable characteristic is an unenviable factor. The utilization of biodegradable polymers or biopolymers is a prominent alternative to petroleum-based plastic products. Reinforcing natural fibers to biopolymer matrices significantly improves the properties of prepared plastic products. Such biopolymer composites have been developed by researchers to provide environmentally responsible materials and thereby reduce carbon footprint. Modification or functionalization of natural fibers is important to ameliorate the interfacial bonding with biopolymers, and to successfully obtain high-performance composite materials that can compete with conventional petrochemical-based polymer composite counterparts. Another widely accepted composite development technique is by combining different types of fibers into a single matrix to develop highly valued hybrid composites. The review focuses on the extraction, processing and characterization of bio-based materials; natural fibers and biopolymers, and their synergistic application and future scope as biopolymer composites in automotive and other growing sectors.

“…18 Sadeghi prepared porous keratin-based sponge with polyvinyl alcohol, which could by potentially used as an oil absorbent. 19 However, there are two problems that cannot be ignored in the current preparation of keratin materials. On one hand, due to the existence of special peptide chains and a large number of hydrogen bonds, van der Waals forces, ionic bonds, especially disulfide bonds that are difficult to cleave, keratin is very difficult to be extracted.…”

To improve mechanical properties of keratin (KR) porous scaffolds, we prepared a PEGylated keratin through thiol-ene click reaction. Several porous scaffolds were prepared by blending PEGylated keratin with sodium alginate (SA). The surface morphology, mechanical properties, and porosity of scaffolds were detailed studied at different KR/SA proportions. The results showed the content of SA had an effect on pore formation and mechanical properties. When the mass ratio of KR to SA was 2:1, the stress of yield point of the keratin porous scaffold reached 1.24 MPa, and also showed good deformation recovery ability. The PEGylated keratin porous scaffold had a high porosity and great cytocompatibility. Its' porosity is up to 81.7% and the cell viability is about 117.78%. This allows it to absorb the simulated plasma quickly (9.20 ± 0.37 g/g). In addition, the structural stability and acid-base stability of the keratin porous scaffold were also improved after PEGylation. Overall, the PEGylated keratin porous scaffold will be promising in tissue materials due to its great physical, chemical, and biological properties.
