A novel method to prepare ultrathin, freestanding polyelectrolyte films in pores, without the need of sacrificial precursor coatings, has been developed (see Figure). The freestanding films are stable under ambient conditions and suited for additional electrostatic self‐assembly or surface modification. They can be specifically decomposed, whereas after thermal crosslinking, resistant films are obtained.
