In article number 2004922, Qiyun Tang, Kai Zhang, and co‐workers report Janus‐like films fabricated via the self‐assembly of surface‐acylated cellulose nanowhiskers (CNWs) with or without graphene oxide (GO). The obtained films with asymmetric topographies and properties on their top and bottom surfaces show different wettabilities and fast solvent‐responsive actuation. The self‐assembled patchy microspheres on the top surface vanish upon heating and recover after cooling down to room temperature with time‐dependent morphologies.
