Nanoincorporation of layered double hydroxides into a miscible blend system of cellulose acetate with poly(acryloyl morpholine)

► A poly(acryloyl morpholine)/cellulose acetate (PACMO/CA) pair forms miscible blends. ► A layered double hydroxide (LDH) was prepared and modified with different ionic oligomers. ► The resulting organophilic LDHs were incorporated as nano-filler into miscible PACMO/CA matrices. ► The extent of improvement in the thermo-mechanical property of the blends was examined. ► 12-Hydroxystearic acid-modified LDH exercised an especially high reinforcement effect.
