“…Both ILs and DES often present extremely low volatilities, and their properties can be adjusted by selecting the nature and ratio of the ion and the hydrogen bonding pairs [58]. They have been used as a mild option for chemical treatments to extract keratin and other natural polymers from their raw sources, especially due to their capacity to keep (or tune) the properties of the original polymer and also due to their recyclability [59].…”

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.

“…Facing to the growing problems in global environmental area, to use environmentally friendly fully biodegradable green composites is substantially increased and expected by various industries and families. [1] Aside from the traditional composites consisting of the nondegradable thermoplastic polymers, [2] e.g., polyethylene, polyesters, poly(methyl methacrylate), and the thermosetting polymers such as the epoxy and polyurethane, the fully biodegradable green composites composing of renewable and sustainable resources [3][4][5][6][7] are recently greatly reported elsewhere. [8][9][10][11][12][13] As a natural and renewable material, the water-soluble tea polyphenols, TP, has been broadly applied as natural antioxidant to eliminate the free radicals in human body, to protect ultraviolet, UV, effect, as the resisting agent for treatment of the cancer, tumor, antiviral, anti-inflammatory and the deodorization.…”

Several fully green composites are prepared by taking the tea polyphenols (TP) with various percentages to blend with poly(vinyl alcohol) (PVA). The as‐prepared PVA/TP composite with only 5% TP shows superb anti‐UV properties even after water washing, the presented UV protection factor (UPF) value is still greater than that of the standard values reported by Australia and New Zealand (AS/NZS 4399‐1996). Moreover, the UPF value of those PVA/TP composites is found capable of furthermore enhancement by increasing the TP percent. This PVA/TP composite also shows good antibacterial and biodegradability while it is kept with certain mechanical properties to fit required application cases.

“…Although imidazoilum‐based ILs have extensively been employed but the synthesis of these popular ILs is often expensive, troublesome, and requires fossil‐based resources. Usually the resulting imidazolium‐based ILs are non‐biodegradable and toxic as well which can definitely restrain the promising interest of this class of ILs at bulk level …”

The evolution of petroleum‐derived polymers is one of the crowning accomplishments of the past century. Although the significant economic gains from this industrial model of resource utilization are achieved, the environmental impacts are fatal. One of the principles of sustainable development is to replace such polymers with potential alternatives derived from renewable materials. Biopolymers derived from natural resources afford a new, versatile, environmentally benign feedstock that could exhibit closed‐loop life cycles as part of a future material's industrial ecology. However, the solubility and processability of biopolymer materials provoke a serious bottleneck owing to their dense networks of inter ‐ and intramolecular bondings and structural heterogeneity. Recently, ionic liquids (ILs) have emerged as promising green solvents and acquired augmented appreciation for their peerless power of biopolymer processing. Among the fourteen principle of green chemistry, the two key elements encourage the exploitation of renewable raw materials by using environmentally benign solvents that cover in dissolution of biopolymers using ILs. This mini review represents a brief overview of the comprehensive ILs assisted extraction and processing of various biopolymeric materials for value‐added applications.
