Digital Photopatterning: Designing Functional Multipolymeric Patterning Films

Abstract

This study proposes a practical patterning technique, digital photopatterning, using a commercial LCD 3D printer to integrate polymeric materials with distinct properties. A parent cross-linked film swollen by additional monomers and a photo radical initiator is irradiated area-selectively using the 3D printer. Polymerization progresses only in the irradiated areas, enabling precise control over material heterogeneity. Through exploring various combinations of parent film and monomers, we demonstrated some unique functions, such as shape morphing and arbitrary gel patterning within the film. This practical and versatile technique has the potential for various applications in materials science and engineering.

Allometric Scaling Reveals Evolutionary Constraint on Odonata Wing Cellularity via Critical Crack Length

“…Our research has potential implications for the design of synthetic wings, crack‐resistant meta‐materials, and thin films. [ 54 ] By comprehending how cells are distributed according to their specific characteristics in insect wings, we can devise better methods to imitate their structural features and improve the longevity of engineering systems for a broad range of applications.…”
