Biopolymer Honeycomb Microstructures: A Review

Materials (Basel). 2023 Jan 12;16(2):772. doi: 10.3390/ma16020772.

Abstract

In this review, we present a comprehensive summary of the formation of honeycomb microstructures and their applications, which include tissue engineering, antibacterial materials, replication processes or sensors. The history of the honeycomb pattern, the first experiments, which mostly involved the breath figure procedure and the improved phase separation, the most recent approach to honeycomb pattern formation, are described in detail. Subsequent surface modifications of the pattern, which involve physical and chemical modifications and further enhancement of the surface properties, are also introduced. Different aspects influencing the polymer formation, such as the substrate influence, a particular polymer or solvent, which may significantly contribute to pattern formation, and thus influence the target structural properties, are also discussed.

Keywords: antibacterial properties; biopolymer; breath figure; honeycomb; improved phase separation; morphology; polymer; replication; surface modification; tissue engineering.
