Abstract Scope |
Scalable fabrication of long-range ordered colloidal nanoparticles is essential for next-generation functional nanomaterials, yet traditional self-assembly struggles with orienting anisotropic particles like zinc sulfide (ZnS) due to competing microforces and poor scalability. To overcome this, we developed a shear-assisted direct ink writing (DIW) platform featuring a bent nozzle that leverages directional shear and polymer-chain templating to achieve precise nanoparticle alignment. This processing innovation minimizes turbulence by optimizing the nozzle’s angle of attack, while rheological tuning enables controlled orientation of ZnS nanoparticles. Confocal Raman and TEM confirm that polymer chains act as dynamic templates, guiding ZnS into aligned low-dimensional (1D/2D) architectures. These structures exhibit anisotropic optical properties for photonic devices and energy harvesting, while enhanced surface area boosts antimicrobial efficacy via ROS generation. By enabling scalable, non-lithographic assembly of functional low-dimensional materials, this work bridges processing concepts and device applications in optics, electronics, and bio interfaces. |
