From: Nano- to macro-scale control of 3D printed materials via polymerization induced microphase separation

a PIMS mechanism: a macroCTA is chain extended with acrylic acid (AA) and poly(ethylene glycol) diacrylate (PEGDA) to form block copolymers, which eventually phase-separate with the generation of emergent morphologies trapped by in-situ cross-linking. b Previous work using PBA-CTA with fixed chain length blended with non-functional PBA to 3D print PIMS materials with limited control over morphology. c Current work using PBA-CTAs with varied chain length to investigate structure-property relationships of 3D printed PIMS materials.
