Abstract

Poly(methylmethacrylate) surfaces were patterned with micropillars and micro-micro hierarchical structures. Patterning was achieved by applying direct fabrication on polymer surfaces. The micro-manufacturing method has many advantages of precise control of dimensions, low cost, and short process time compared to other micro-manufacturing techniques of polymers. Fabricated structures were controlled accurately to <10% of the error range. Patterned micro-micro hierarchical polymer structures indicated a contact angle >130° without additional coatings. Furthermore, fabricated structures show good durability in terms of contamination and mechanical robustness for 2 months.
