Surface texturing of catechol derivative urushiol was achieved using a thermal imprinting technique. An indented surface was obtained by thermal curing at 100 °C for 10 min while pressing an urushi film with a patterned mold. The indented surface enhanced the static water contact angle in comparison with the flat urushi film.
