We demonstrated a novel technique to fabricate nanosized structures on a Nafion membrane, using thermal nanoimprinting with a 5 × 5 μm2 square pattern Si mold without any polymer damage. A 24 MPa thermal imprinting pressure was used for 10 min. We observed high aspect ratio (∼1:10) pillars on the surface after imprinting at 200°C. Finally, we used a novel quartz mold with a 200 nm resolution dot pattern.
