Abstract Scope |
Nanofiber-reinforced composites have provided tremendous opportunities in advanced engineering material design. However, the control over the spatial distribution of nanofibers is the primary challenge in manufacturing nanocomposites. Our research focuses on developing an innovative fabrication approach for nanofiber-reinforced composites with spatially resolved fiber distribution based on a modified electrospinning process. We explore the viability of directly generating nanofibers inside a viscous liquid matrix to yield nanofiber-reinforced composites with controlled distribution and deposition of nanofibers. Our process, inspired by 3D bioprinting, makes use of a high electrostatic force to draw nano-scale fibers inside the liquid bath matrix and allows the freestanding of the electrospun nanofibers with the support of the liquid bath. This novel approach enables dynamic control of the fiber morphology and the fiber 3D spatial distribution inside the composites and further leads to a scalable manufacturing approach of multifunctional nanofiber-reinforced composites and potential advances in micro-scale 3D printing. |
