It remains a challenge to maintain the antiadhesion properties of superhydrophobic films after exposure to bacterial environments. In this work, superhydrophobic bactericidal polymer films via the simple incorporation of polyvinylpyrrolidone‐iodine (PVP‐I) or iodine into polytetrafluoroethylene (PTFE) are fabricated to improve their antiadhesive and antibacterial capability. Superhydrophobic iodine‐embedded films, polytetrafluoroethylene/polyvinylpyrrolidone‐iodine and polytetrafluoroethylene‐iodine (PTFE/PVP‐I and PTFE‐I), show excellent antiadhesive and bactericidal performances even post exposure to bacterial solutions as compared to iodine‐free counterparts by controlling the release of iodine. Especially, superhydrophobic PTFE/PVP‐I films display a more sustained iodine release profile and significant antibacterial properties against gram‐positive ( S. aureus , methicillin‐resistant S. aureus (MRSA)) and gram‐negative ( E. coli ) bacteria. Such a facile combination of antiseptic agents and superhydrophobic surface could be widely used for antiseptic biomedical applications.
