Comb‐like cellulose stearoyl ester (CSE 3 ) and poly(vinyl stearate) (PVS) with distinct skeletons are successfully synthesized. Their self‐assembled superstructures are described and discussed comparatively herein. Differential scanning calorimetry investigation indicates that both comb‐like polymers with various molecular weights show the feasibility to form self‐assembled crystalline structures. The self‐assembled superstructures are obtained from both the evaporation‐induced and temperature‐induced phase separation processes. Due to the interference of different skeletons, self‐assembled superstructures of both comb‐like polymers demonstrate totally different morphologies. CSE 3 with semi‐flexible skeleton forms robust petals, which further grows into well‐organized flower‐like particles. In contrast, PVS with more flexible skeleton only form non‐ordered porous structures through stacking of the wrinkled and folded nanofilms.
