Generation of controlled monodisperse porous polymer particles by dipped inkjet injection

Abstract

A piezoelectric drop-on-demand (DOD) inkjet microchip with its nozzle immersed in organic phase was used to generate monodisperse porous polymer particles.

A microfluidic method generating monodispersed microparticles with controllable sizes and mechanical properties

“…Moreover, Figure 7a shows that df increases with both Ci and di. Similar results were previously found for porous microparticles of Na-poly(styrenesulfonate) formed by inkjet injection (Yang et al, 2015). In our study, for each Ci, df versus di is fitted by a power law.…”

“…After total evaporation of DMC, an aqueous CaCl2 solution is added to the collecting vial containing dried Na-alginate microparticles. The cation of calcium (Ca 2+ ) induces cross-linking (Yang et al, 2015), thus transforming Na-alginate microparticles into Ca-alginate microparticles. Immediate swelling is observed when CaCl2 (0.5%, 1% or 10wt%) is added.…”

Nanocomposite capsules with directional, pulsed nanoparticle release

“…Capsules produced from droplets of neat polymer solution, shown in Fig. 4 (C and D), exhibit smooth shells, and their internal pore size can be tuned by varying the initial C NaPSS ( 26 , 27 , 39 ). Figure 4 (E and F) illustrates dense dimpled capsules produced from neat nanoparticle droplets.…”
