“…The new approach is cost effective and alternative to commonly used coatings for example, collagen and fibronectin [81]. Recently, several researchers developed films from native keratin, by using reducing agents and different plasticizers, either via compression molding [82] or extrusion and subsequent compression molding [11,83] leading to improved mechanical properties.…”

A great deal of environmental concerns, oil price hike, and rapid oil consumption with finite nature of oil reserves in addition to consumer demand is driving research into renewable, biodegradable, inexpensive, and abundantly available biopolymers in material chemistry. Poultry feathers consist of keratin protein with several amino acids especially cysteine as a major component. Keratin is an original raw material that has great potential to be used in the development of novel fibrous composite materials. Being very effective biopolymer, keratin possesses numerous functional properties, bioactivities, and chemical applications in material chemistry, for example, keratin based gels, films, nano/micro-particles, and beads are of paramount importance. Modified keratin also serves as a biosorbent for removing toxic metal ions from water resources on account of exceptionally important role of functional groups for keratin-metal binding. This review focuses on the recent advances of keratin in material chemistry including its significant role as biosorbent in green chemistry.

“…Consequently, various natural protein fibers such as feather fiber, wool fiber and silk fiber have been straightly applied as filler to produce composites [1][2][3][4][5][6][7][8]. Feather fibers have been thermally preceded into protein films by using convenient plasticizing agents, such as glycerol and soybean oil [9][10][11]. However, the film modified by glycerol showed higher weight loss of glycerol, which limited its application.…”

Down feather fiber was modified by formamide which acts as a plasticizer and then hot-pressed into thermoplastic down films. After hot-pressed, the mechanical properties of thermoplastic down films had a close relationship with the exposure time periods. The maximum tensile strength of thermoplastic down films can reach 28.74 MPa after exposure to atmosphere for 40 days. ATR-FTIR curves proved that there were hydrogen bonds forming between amino and amide groups of down feather fiber and formamide. WXRD patterns showed that the crystalline region of down feather fiber was destroyed by formamide during hot-pressing and then reformed after exposure to atmosphere for several days. TGA curves showed that thermoplastic down films has lower moisture compared with down feather fiber suggesting that high temperature removed the most of hydrogen-bound water in down feather fiber and then there are chemical reaction between down feather fiber and formamide.

“…The findings support the view that the cell membrane complex and other low sulphur regions are the main route of entry for both molecular and macromolecular treatment chemicals. The use of this technique to treat wool may lead to new coloration effects and other functions such as antimicrobial action [4][5][6][7][8][9][10][11][12][13][14]. …”

Sliver nanocolloids have been synthesized by chemical reduction of sliver salt solution, characterized by SEM usage of nanoparticles. Sliver nanocolloids are treated with wool fibres and dyed wool fibres (direct and acid dyes). The physical properties, colour strength, and fastness properties have been studied for dyed wool fibres and ordinary wool fibres. It is observed that the fibres with nanotreated fibres have better strength than untreated wool fibres. It is also observed that there is considerable improvement in colour strength and colour fastness of silver nanocolloids-treated wool fibres (dyed).
