“…Consequently, they are also among the main contributors for the huge environmental impact caused by, in particular, the packaging industry; and the blending of polyolefins with available natural polymers has been a feasible option to tackle this issue [102]. Very recently, Shavandi and Ali published a review summarizing the processing conditions and thermomechanical properties of blends between wool and feather keratin and some polymers, especially PP and PE [103].…”

Among the biopolymers from animal sources, keratin is one the most abundant, with a major contribution from side stream products from cattle, ovine and poultry industry, offering many opportunities to produce cost-effective and sustainable advanced materials. Although many reviews have discussed the application of keratin in polymer-based biomaterials, little attention has been paid to its potential in association with other polymer matrices. Thus, herein, we present an extensive literature review summarizing keratin’s compatibility with other synthetic, biosynthetic and natural polymers, and its effect on the materials’ final properties in a myriad of applications. First, we revise the historical context of keratin use, describe its structure, chemical toolset and methods of extraction, overview and differentiate keratins obtained from different sources, highlight the main areas where keratin associations have been applied, and describe the possibilities offered by its chemical toolset. Finally, we contextualize keratin’s potential for addressing current issues in materials sciences, focusing on the effect of keratin when associated to other polymers’ matrices from biomedical to engineering applications, and beyond.

“…The third section, “ Keratin as a Material for Engineered Systems ” discusses how keratin's intrinsic material properties are harnessed for various engineering applications, focusing on biomaterials and fiber-reinforced composites. Although there are nearly twenty existing reviews of keratin and keratin-based materials, many of them focus on its structure and properties ( Bradbury, 1973 ; Chapman, 1969a ; Marshall et al., 1991 ; McKittrick et al., 2012 ; Norlén, 2006 ; Wang et al., 2016a ; Wang and Sullivan, 2017 ), use as a biomaterial for biomedical applications ( Donato and Mija, 2019 ; Feroz et al., 2020 ; Rouse and Van Dyke, 2010 ; Shavandi et al., 2017 ), or extraction techniques ( Chilakamarry et al., 2021 ; Donato and Mija, 2019 ; Feroz et al., 2020 ; Khosa and Ullah, 2013 ; Shavandi and Ali, 2019 ), and there are only a few reviews that acknowledge keratin-based bioinspired materials ( McKittrick et al., 2012 ; Wang et al., 2016a ) ( Table 1 ). None of the reviews that include bioinspiration are recent; much progress has been accomplished that warrants an updated review.…”

Engineering with keratin: A functional material and a source of bioinspiration

Summary Keratin is a highly multifunctional biopolymer serving various roles in nature due to its diverse material properties, wide spectrum of structural designs, and impressive performance. Keratin-based materials are mechanically robust, thermally insulating, lightweight, capable of undergoing reversible adhesion through van der Waals forces, and exhibit structural coloration and hydrophobic surfaces. Thus, they have become templates for bioinspired designs and have even been applied as a functional material for biomedical applications and environmentally sustainable fiber-reinforced composites. This review aims to highlight keratin's remarkable capabilities as a biological component, a source of design inspiration, and an engineering material. We conclude with future directions for the exploration of keratinous materials.

“…Keratin contains a high number of cysteine residues that are responsible for the many intramolecular and intermolecular interactions, leading to higher stability and lower solubility of the protein [ 1 , 22 ]. Keratins are usually insoluble because of the disulfide bonds [ 23 , 24 ].…”

Protein/peptide-based hydrogel biomaterial inks with the ability to incorporate various cells and mimic the extracellular matrix’s function are promising candidates for 3D printing and biomaterials engineering. This is because proteins contain multiple functional groups as reactive sites for enzymatic, chemical modification or physical gelation or cross-linking, which is essential for the filament formation and printing processes in general. The primary mechanism in the protein gelation process is the unfolding of its native structure and its aggregation into a gel network. This network is then stabilized through both noncovalent and covalent cross-link. Diverse proteins and polypeptides can be obtained from humans, animals, or plants or can be synthetically engineered. In this review, we describe the major proteins that have been used for 3D printing, highlight their physicochemical properties in relation to 3D printing and their various tissue engineering application are discussed.
