“…Similar results were also reported in the other reports about the cellulose dissolution and regeneration process in ionic liquids (Zhang et al 2005). A broad vibration band around 3284 cm − 1 is assigned to the O-H vibrations of cotton pulp, while the -OH stretching vibration band in the C-A-40 shifts to a higher frequency (3337 cm − 1 ) and becomes sharper and narrower as a result of splitting hydrogen bonds to some extent during the dissolution and regeneration process (De Silva et al 2015). A new shoulder round 899 cm − 1 is observed only in the C-A-40 but not in the cotton pulp, which is assigned to the C-O stretching vibration in the amorphous region (Zhang et al 2005).…”

A series of cellulose films with rough surface were prepared by employing a simple solution casting method and using the waterproof abrasive papers with different grits as the substrate. The cellulose films possessed a rough surface with the maximum height difference (Sz) of 128-217 μm, a macroporous structure with a high porosity of 84.7%-90.5%, and a negative potential between -40.00 and -54.15 mV. Furthermore, the cellulose films exhibited excellent microalgae adhesion properties. After 18 days of attached Chlorella sp. cultivation experiments, the average productivities of C-A-120 films (C-A-X, X means the mesh number of the substrate) reached 20.80 g m-2 d-1), which is 2.69 times than that of the cellulose film with a smooth surface. The result indicates that the cellulose films with a rough surface and high water adsorption ratio have a huge potential in serving as the substrate of the attached microalgae cultivation to promote microalgae cells growth and biofilm formation.

“…% feather content. However, in this case, the authors attribute the elastic properties improvement to a larger amount of α-helix keratin in the composite films [267]. Later on, they used the same cellulose/duck feather composite to be wet-spun (extruded), from an ionic liquid solution, into fibres.…”

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.

Hydroxypropyltrimethylammonium chloride cellulose (CM) was homogeneously synthesized in a NaOH/urea aqueous solution. CM was blended in a polyvinyl alcohol (PVA) matrix to produce composite films via co‐regeneration from the alkaline solution. The PVA film and the blend films were characterized by Fourier transform infrared spectroscopy, X‐ray diffraction measurements and scanning electron microscopy. The mechanical properties, water swelling ratio, hydrophobicity, light transmission, and antibacterial activity against Staphylococcus aureus and Escherichia coli were also evaluated. The results showed that CM could interact with PVA by hydrogen bonding and exhibit an obvious reinforcement effect. The addition of CM improved the surface roughness, hydrophobicity and water swelling ratio, especially, the antibacterial activity. However, compared with neat PVA film, the elasticity and optical transmission decreased. The increased tensile strength, powerful antibacterial activity, and medium light transmission indicate that the biocompatible blend film will become an exceptional alternative in functional bio‐material field. © 2016 Wiley Periodicals, Inc.
