“…Wool and chicken feathers are mainly composed of keratin, a structural protein similar to SF. The chemical structure of keratin is predominantly an α-helix in chicken feathers [55] and a super coiled polypeptide chain with an α-helix and β-sheet in wool [56]. These structures are tightly packed via cross linkages, hydrogen bonds, Van der Waals and electrostatic interactions.…”

In the last ten years, environmental consciousness has increased worldwide, leading to the development of eco-friendly materials to replace synthetic ones. Natural fibers are extracted from renewable resources at low cost. Their combination with synthetic polymers as reinforcement materials has been an important step forward in that direction. The sustainability and excellent physical and biological (e.g., biocompatibility, antimicrobial activity) properties of these biocomposites have extended their application to the biomedical field. This paper offers a detailed overview of the extraction and separation processes applied to natural fibers and their posterior chemical and physical modifications for biocomposite fabrication. Because of the requirements for biomedical device production, specialized biomolecules are currently being incorporated onto these biocomposites. From antibiotics to peptides and plant extracts, to name a few, this review explores their impact on the final biocomposite product, in light of their individual or combined effect, and analyzes the most recurrent strategies for biomolecule immobilization.

“…A recent study of Gu and Catchmark explored on the use of amphiphilic whole milk casein as dispersant in cellulose nano‐whisker reinforced PLA composites. This amphiphilic property is available in renewable protein, keratin that is found abundantly in hair, wool, and feathers at approximately 90%, which allow keratin to be used as a whole in composite processing without separating the quill from the fibers to save time, cost, and production energy . Global meat manufacturers produce an estimated 15 million tons of chicken feather annually and could cause environmental pollution.…”

Amphiphilic keratin from chicken feather fiber (CFF) and hydrophilic cellulose were incorporated as fillers into hydrophobic poly(lactic acid) (PLA) polymer blend. This study implemented ionic liquid (IL) of 1-butyl-3-methylimidazolium chloride (BMIMCl) to dissolve the 1 wt % fillers. The composite films were compared with and without the addition of IL prepared from five sets of ratios of CFF to MCC using measuring mixers and compression molding. Thermal analysis showed that increase in CFF composition decreases the glass-transition temperature (T g ), and crystallization temperature (T c ) as well as increases the degree of crystallinity. PLA composite with the 70/30 ratio of CFF to MCC was found to be the optimum composition in obtaining considerably low T g and high crystallinity. BMIMCl enhanced the miscibility of the composites as observed in scanning electron microscope images and single T g . Apart from creating porous structure and lowering mechanical hardness, BMIMCl also decreased the thermal stability of the PLA composites.

“…In addition, incineration is not a suitable treatment method because the burning of keratin can lead to environmental pollution [12]. Hence, the idea of using CFs waste to fabricate more environmental friendly composite materials, by means of the partial substitution of the polymer with CFs, has attracted attention during last years [13,14]. In such scenario, CFs provide multiple advantages as they are inexpensive, non-abrasive, insoluble in organic solvents, biodegradable and have a low density [15].…”

“…Being made of keratin, CFs are reported to have a low density, approximately 0.9 g/cm 3 [16], and this fact opens the possibility of fabrication of light composite materials. In addition, CFs have demonstrated a thermal stability up to 190-205 °C due to the hydrogen bonds, S-S cross linking, Van der Waals and electrostatic interactions that characterize its chemical structure [13]. Consequently, the processing of CFs combined with the majority of polymeric matrices is possible since most of the conventional thermoplastics melt below that temperature.…”

“…Some solutions have been proposed to improve affinity of those components, resulting in an improvement of the mechanical properties. On the one hand, some chemical modifications can be performed in order to modify the surface properties of natural fibres creating groups that increase the adhesion to the matrix [13]. On the other hand, additives such as adhesion promoters based on the modification of polymer matrices with maleic anhydride have also been successfully used in order to improve mechanical properties of the composites [18].…”

The valorization of chicken feathers (CFs) waste was researched in this work through the preparation of composites using ground chicken feathers as a filler (20 % v/v) and polypropylene (PP) or low-density polyethylene (LDPE) matrices. In order to improve the compatibility between CFs and the matrixes two different strategies were followed. First, by the chemical modification of the CFs by either acetylation or silanization and, second, by the addition of adhesion promoters like maleated polypropylene (MAPP) and maleatead 2 polyethylene (MAPE). The effect of those treatments on the physical, mechanical and structural properties of the thermoplastic-CFs biocomposites, which are mainly related to the fibre-matrix compatibility, was analyzed. Results show that the addition of 20 % (vol/vol) of unmodified CFs to the thermoplastic matrices results in a significant decrease of the tensile strength associated to a weak interfacial adhesion was assessed by SEM. However, when the adhesion promoters were added to the mixture, a significant increase in the tensile strength was noticed, particularly when the composites were obtained by a process at 180 °C. On the contrary, acetylation and silane treatments of the CFs did not result in any practical improvement of the macroscopic properties of the biocomposites.
