Photonic Crystal-Engineered PVDF Membranes: Rapid Scalable Fabrication of Inverse Opal Architectures for High-Precision Separation.

ABSTRACT: Photonic crystal (PC) inverse opal (IO) structure is an ordered interconnected pore structure that is extremely advantageous for realizing high-precision separations. However, this structure is difficult to prepare quickly over a large area. Here, we designed a preparation strategy for PCs and a shear-induced assembly method based on the shear force. Porous membranes were prepared within 10 s in a fast and large area (900 cm²). We then explored the effects of factors such as casting liquid parameters and the preparation process on the structure and properties of PC membranes. The process and mechanism of membrane formation by shear-induced assembly were analyzed. The membranes with IO structures having different pore sizes fabricated after removing microspheres were also analyze
