“…Many researchers aim to tackle this problem with biodegradable, renewably sourced composites made of biopolymer matrixes and natural fibers. Knowledge of the properties of available biodegradable polymers and natural fibers is essential for manufacturing a biodegradable composite ( Shrivastava and Dondapati, 2021 ).…”

Summary Keratin is a highly multifunctional biopolymer serving various roles in nature due to its diverse material properties, wide spectrum of structural designs, and impressive performance. Keratin-based materials are mechanically robust, thermally insulating, lightweight, capable of undergoing reversible adhesion through van der Waals forces, and exhibit structural coloration and hydrophobic surfaces. Thus, they have become templates for bioinspired designs and have even been applied as a functional material for biomedical applications and environmentally sustainable fiber-reinforced composites. This review aims to highlight keratin's remarkable capabilities as a biological component, a source of design inspiration, and an engineering material. We conclude with future directions for the exploration of keratinous materials.

“…Polymer composites with natural fibers based on a biodegradable matrix are also very popular. Such polymers include polylactide, polyglycolide, polyhydroxyalkanoates, and polycaprolactone [ 38 , 39 , 40 , 41 , 42 , 43 , 44 , 45 ]. The properties of composites with natural fibers are influenced by the type of ingredients used, the selection of proportions between the biopolymer matrix and the filler used, and the type of interactions between the hydrophilic phase and the hydrophobic phase.…”

This study focuses on examining the influence of bast fibers on the flammability and thermal properties of the polylactide matrix (PLA). For this purpose, Urtica dioica and Vitis vinifera fibers were subjected to two types of modifications: mercerization in NaOH solution (M1 route) and encapsulation in an organic PLA solution (M2 route). In a further step, PLA composites containing 5, 10, and 15 wt% of unmodified and chemically treated fibers were obtained. The results of the tests show that only biocomposites containing mercerized fibers had a nearly 20% reduced flammability compared to that of PLA. Moreover, the biofiller obtained in this way belongs to the group of flame retardants that generate char residue during combustion, which was also confirmed by TGA tests. The M2 modification route allowed to achieve higher mass viscosity than the addition of unmodified and M1-modified fibers. The reason is that fibers additionally encapsulated in a polymer layer impede the mobility of the chain segments. The inferior homogenization of the M2-modified fibers in the PLA matrix translated into a longer combustion time and only a 15% reduction in flammability.

“…The new trend in composite materials development, which is made utilizing natural or synthetic matrix and reinforcement materials, is a result of rising environmental concern. For a variety of applications, the development of commercially viable biodegradable composites based on natural sources is on the rise [1][2][3][4]. When natural fibers (bio fibers) like wood (hardwood and softwood) or nonwood fibers (such wheat, kenaf, hemp, jute, sisal, and flax) are combined with polymer matrix (resin) derived from both renewable and nonrenewable resources, the result is a material known as a bio composite.…”
