However, many self-assembled structures by NPs are irreversible, because they are generally constructed using their suspensions. It is still challenging for NPs to reversibly self-assemble in dry state, let alone of polymeric NPs with general sizes of hundreds of nm. Herein, this study reports a new reversible self-assembly phenomenon of NPs in dry state, forming thermoreversible strip-like supermolecular structures. These novel NPs of around 150 nm are perfluorinated surface-undecenoated cellulose nanoparticles (FSU-CNPs) with a core-coronas structure. The thermoreversible self-assembled structure is formed after drying in the air at the interface between FSU-CNP films and Teflon substrates. Remarkably, the formation and dissociation of this assembled structure are accompanied by a reversible conversion of the surface hydrophobicity, film transparency, and anisotropic properties. These findings show novel feasibility of reversible self-assembly of NPs in dry state, and thereby expand our knowledge of self-assembly phenomenon.","lang":"eng"}],"date_created":"2026-02-07T16:16:37Z","author":[{"first_name":"Yonggui","last_name":"Wang","full_name":"Wang, Yonggui"},{"last_name":"Groszewicz","full_name":"Groszewicz, Pedro B.","first_name":"Pedro B."},{"last_name":"Rosenfeldt","full_name":"Rosenfeldt, Sabine","first_name":"Sabine"},{"first_name":"Hendrik","last_name":"Schmidt","full_name":"Schmidt, Hendrik"},{"first_name":"Cynthia A.","full_name":"Volkert, Cynthia A.","last_name":"Volkert"},{"full_name":"Vana, Philipp","last_name":"Vana","first_name":"Philipp"},{"id":"118165","full_name":"Gutmann, Torsten","last_name":"Gutmann","first_name":"Torsten"},{"last_name":"Buntkowsky","full_name":"Buntkowsky, Gerd","first_name":"Gerd"},{"first_name":"Kai","full_name":"Zhang, Kai","last_name":"Zhang"}],"date_updated":"2026-02-17T16:12:48Z","doi":"10.1002/adma.201702473","title":"Thermoreversible Self-Assembly of Perfluorinated Core-Coronas Cellulose-Nanoparticles in Dry State","citation":{"ama":"Wang Y, Groszewicz PB, Rosenfeldt S, et al.
