“…Copolymerization of butadiene, e.g., with styrene forming styrene-butadiene rubber (SBR) or with acrylonitrile forming nitrile-butadiene rubber (NBR), is generally used for improving the chemical resistance and producing elastomers that are resistant to oil and chemicals [214]. However, most butadiene rubber applications demand blending with inorganic fillers or other polymers to acquire enough mechanical properties [215], in which the application of biopolymers can improve their post-use biodegradability [216].…”

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.

“…Elastomer is a loosely crosslinked polymer that has an amorphous structure with excellent elasticity and flexibility since its glass transition temperature is very low and normally below the service temperature. Elastomers can be natural rubber (NR) obtained from natural rubber latex or synthetic rubbers such as epoxidized natural rubber, cis ‐1,4‐polyisoprene, liquid polybutadiene (LPB), ethylene propylene diene (EPDM), acrylonitrile butadiene rubber (NBR), silicone rubber and so on. The overview of toughening PLA by elastomers has been well reported by Alias and Ismail .…”

We report here the morphology, thermal and tensile properties of poly(lactic acid) (PLA) blends composed of acrylonitrile butadiene rubber (NBR) with different acrylonitrile contents with/without dynamic vulcanization by dicumyl peroxide (DCP). The interfacial tension of PLA and NBR measured by contact angle measurement decreased as the acrylonitrile content of NBR decreased. Likewise, SEM images showed that the rubber particle size reduced with decreasing acrylonitrile content owing to the stronger interfacial adhesion between the PLA matrix and NBR domains. Incorporation of DCP at 1.0 phr for dynamic vulcanization led to higher crosslink density and, in turn, optimal tensile strength and tensile toughness as a result of the action of PLA-NBR copolymer as a reactive compatibilizer. The dynamic vulcanization of the blends containing low acrylonitrile NBR gave the most improved tensile properties because the free radicals from DCP decomposition preferentially attacked the allylic hydrogen atoms or double bonds of the butadiene backbone. Accordingly, more NBR macroradicals were generated and probably more PLA-NBR copolymers were produced. Moreover, further addition of DCP at 2.0 phr provided a large amount of crosslinked NBR gel, which significantly degraded the tensile properties. From the DSC results, dynamic vulcanization lowered the cold crystallization temperature, implying an improvement of cold crystallization. Finally, TGA results showed a higher degradation temperature as a function of DCP content, which suggested that thermal stability increased due to stronger interfacial adhesion as well as higher gel content.

“…Incorporation of nanofillers as reinforcements into PLA matrix has been proved as an effective way to tailor the properties of composites . Among many nanofillers employed as nano‐reinforcements for biopolymers, cellulose nanowhiskers are gaining increasing interest as a small amount of them can improve the toughness of PLA and maintain the fully degradable and transparent properties of the composite .…”

To improve the surface compatibility between hydrophobic poly(lactic acid) (PLA) and hydrophilic bamboo cellulose nanowhiskers (BCNWs), four commercial available silane coupling agents were employed to modify their interfaces with different concentrations (0, 1, 8, and 16 wt%). PLA/BCNW biocomposite films were fabricated by solution casting. The effects of silylated BCNW on the thermal, mechanical, and morphological properties of PLA biocomposites were investigated. The coupled reaction between coupling agents and cellulose via Si‐O‐C bonding and hydrogen bonding was confirmed. Both, tensile strength and tensile modulus, decreased with the four silane treatments. The maximum elongation at break values increased to 213.8, 111.3, 255.3, and 209.8% after 16 wt% A‐151, 8 wt% A‐1100, 8 wt% A‐174, and 8 wt% A‐189 silane treatments, respectively, with respect to 12.4% of the untreated composite. A wire‐drawing phenomenon was observed on the tensile fractural surface. Glass transition temperature and crystallinity decreased after the surface modifications. POLYM.
