Bioinspired nano-architecture cellulose fibers spider Project Details
| Abstract |
This study investigates the creation of regenerated cellulose fibers with improved toughness inspired by natural bio-architectures. Despite the high tensile strength, due to molecular alignment, the toughness of renewable biomass cellulose fibers is always limited. Here we propose a bioinspired nano-orientation approach, namely a constitutive microstructure biaxial orientation, designed under a scalable microfluidic spinning process. In combination with molecular simulations, experimental measurements show that this new nano-architecture alters the stress distribution and inhibits the propagation of cracks during deformation. Compared to other fibers and synthetic polymers, the achievable fracture strain of 41% and tensile strength of 553 MPa, yields a toughness of 184 MJ m−3, contending the mechanical characteristics of
natural spider silk. The properties obtained are scalable from individual fibers to woven fabrics, offering remarkable potential for sustainable high-performance materials across an extensive range of applications from textiles to automotive and aerospace structures. This study provides solutions for the inherent brittleness of cellulose fibers and their ecological viability in structural applications.
