Abstract Scope |
The creatures in nature exhibit unique functional performances due to hierarchical architectures composed of nanofillers and the polymer-based matrix. Traditional manufacturing and 3D printing methods have been previously used to fabricate biomimetic anisotropic composites by aligning cellulose fillers in a polymer or ceramic matrix, using external directional physical fields or shear forces. However, only certain types of functional fillers, which are responsible for external physical fields or shear forces, can be aligned with simple orientations and patterns using the aforementioned techniques. Here, we present a versatile 3D printing technology, named liquid crystal templating assisted 3D printing (LCT-3DP), that can fabricate nanocomposites by distributing nanofillers inside the polymer-based matrix in a programmable fashion. In this study, the properties of LCT-3D printed polymer matrix composites (PMCs) were evaluated, and the design of bioinspired hierarchical architectures of such printed PMCs was further optimized through physics-based multiscale modeling, simulation, and testing. |
