Self‐Assembly of Adjustable Micropatterned Graphene Oxide and Reduced Graphene Oxide on Porous Polymeric Surfaces

The breath figure (BF) method is a simple technique for fabricating micropatterned surfaces but has been rarely studied using graphene oxide (GO) or reduced GO (rGO). Additionally, fabrication of rGO (MPGO MPrGO) by the BF focuses on smooth and dense inorganic substrates, investigation adjusting MPGO morphology limited. This research systematically studies self-assembly MPrGO surface two model porous polymers explores its potential applications modification. It found that size range 1–50 µm structures can be adjusted changing process parameters. Specifically, under specific conditions, uniform honeycomb obtained. Surface characteristics demonstrate unique alters water contact-angle from ≈65° to ≈100° decreases resistivity 1–5 kΩ cm−2. coating microfiltration membrane gives it much greater permeability than without antibiofilm properties. Overall, this study shows with adjustable morphologies are easily obtained polymeric surfaces, thus altering properties giving various applications.
