Here, we introduce APCNs as shell material for double emulsion-derived microcapsules. The type of APCN that we selected to prepare double emulsion microcapsules is poly(2-hydroxyethyl acrylate)linked by-polydimethylsiloxane (PHEA-l-PDMS), a material which has been of long-standing research interest for our and other research groups. These APCNs are elastic materials, and have been investigated for applications including: semipermeable membranes, as matrix for phase transfer reactions of enzymes in organic solvents and supercritical CO2, as light-responsive membranes, controlled release antimicrobial coatings, as matrix for luminescent solar concentrators, as material for colorimetric (bio)sensors, and as self-sealing and puncture resistant breathable membranes. Additionally, PHEA-l-PDMS APCNs can be functionalized post polymerization by using the active ester pentafluorophenyl acrylate as an additional comonomer, or they can be mechanically reinforced by incorporation of peptide blocks between the PDMS segments and the crosslinking points. Previously, PHEA-l-PDMS APCNs have been studied as coating on surfaces, as freestanding films and membranes, as well as solid microparticles, but not as capsules.
