Bouligand structure is a kind of fiber-reinforced structure that can achieves excellent mechanical performance through biomimetic design of multi-level oriented structures and their inherent strength and toughness mechanisms. This work focuses on the current situation where it is difficult to precisely manufacture the biomimetic Bouligand structures and regulate the mechanical performance. Based on modular design principles and digital additive manufacturing technology, a systematic study was conducted on the multi-level filaments orientation design and interface control of biomimetic Bouligand structures. 3D printed modular Bouligand dissipative structure arrays with adjustable mechanical performance were constructed in a hierarchical manner.

The ease of oxidation of the highly reactive InP cores leads to high non-radiative recombination and poor photoluminescence quantum yield of the InP-based core/shell quantum dots, limiting the performance of the relevant QLEDs. Here, a fluoride-free synthesis strategy was proposed to in-situ passivate the InP cores, in which zinc myristate reacted with phosphine dangling bonds to form Zn-P protective layer and protect InP cores from the water and oxygen in the environment. Further by growing ZnSe/ZnS shell, a high-brightness green InP-based QLED was achieved.
