The Pickering emulsion stabilized by cellulose nanocrystals prepared from sisal fiber (SCNCs) was used as a template to fabricate PMMA or curcumin loaded PMMA composite microspheres coated by SCNCs (PMMA@SCNC or Cur‐loaded PMMA@SCNC CMs) via solvent evaporation. The core‐shell structure of PMMA@SCNC CMs can protect the curcumin loaded and improve its UV light resistance and thermal property. Meanwhile, the Cur‐loaded PMMA@SCNC CMs have good controlled release for curcumin. This work by Xinli Xiao and colleagues offers a facile and general method of preparing new functional microsphere for the delivery of bioactive compounds. (DOI: 10.1002/app.46127 ).
