Online Microfluidic Production of Sustainable Cyrene™-Derived Porous Microparticles

The use of sustainable raw materials is now a necessity in all industries, including the production porous microparticles. Cyrene™ cellulose-derived compound that readily prepared through reduction α,β-unsaturation levoglucosenone (LGO)—a wood-based platform molecule. In this work, importance as potential bio-based molecule to produce microparticles demonstrated. First, methacrylic derivative (m-Cyrene) was synthesized. A microfluidic co-flow device then established m-Cyrene-based oil-in-water (O/W) controlled-size emulsions and polymerize them by ultraviolet (UV) radiation vial. continuous phase sodium dodecyl sulfate aqueous solution, dispersed mixture m-Cyrene with anhydride (MAN) at two different mass concentrations (i.e., 1 wt.% MAN 92 MAN) 2,2-dimethoxy-2-phenylacetophenone (DMPA) photoinitiator. process used lowest possible quantity avoided excessive purifications homogeneous m-Cyrene-MAN controlled size distribution produced polymer were confirmed scanning electron microscope (SEM) images. 3D microstructure well porosity determined using X-ray microtomography. high-resolution images indicate pores are their controllable concentration monomer (porosity 30% for ratio 2% ratio). Such control very important future encapsulation processes require precise release control.
