This cover by Naoto Tsutsumi and colleagues show a series of odd‐odd nylon spin‐coated thin films (nylon 11‐11, nylon 9‐13, and nylon 11‐13) melt‐quenched and subsequently annealed. This process produces polarization switching, which leads to ferroelectric responses including remanent polarization and coercive field. γ crystal phase of these nylons with weak hydrogen bonding and a considerably smoothed surface are responsible for the ferroelectricity. The drive voltage of the present ferroelectric devices ranges from 8 to 18 V and no stretching is required, which is very attractive for the application of organic electronic devices.
