摘要: Flower-like particles (FLPs) with hierarchical surface architectures have recently attracted considerable attention due to their potentially wide application range. Hitherto, nearly all FLPs were fabricated using inorganic compounds, while versatile organic polymers not received sufficient yet. Herein, we show the construction of novel organic, polymeric diameters 2.5–5 μm cellulose stearoyl esters (CSEs) by means crystallization side chains. CSEs degrees substitution approximately 3 transformed into during gradual precipitation polymer chains from mixture solutions in dichloromethane (DCM) and a nonsolvent, which is driven evaporation DCM. Ordered petal-like nanostructures formed on particle through Finally, partially crystalline containing lamellar structures obtained. Moreover, formation process was strongly affected molecular weight of...
