Initial Poly(HIPE) Segments Photo initiator BDM (32 mg) was dissolved in a mixture of EHA (0.65 mL), DEGDA (0.15 mL) and span 80 (0.20 mL) in a 50 mL beaker. While this mixture is being stirred vigorously by a magnetic stirbar, 9 mL NaCl solution (0.1 M) was added dropwise. Obtained HIPE was viscous and stable. The discrete phase syringe was filled with this HIPE and pumped with a rate of 0.5 mL/h. Continuous carrier phase in microfluidics was 3% SDS, pumped with a rate of 6 mL/min. A piece of 3m PVC tubing and a straight blunt 22G needle was used. LA HIPE was prepared just by replacing EHA with LA in the mentioned procedure.
