3D-Printable Nanoporous Thermosets via Disulfide-Based Polymerization-Induced Microphase Separation. [PDF]

Angew Chem Int Ed Engl
α‐Lipoic acid‐derived degradable macro‐chain transfer agents (macroCTAs) with tunable hydrophilicity drive polymerization‐induced microphase separation (PIMS) in photocurable resins. Selective etching via disulfide cleavage then generates interconnected nanoporous thermosets, and compatibility with liquid‐crystal display (LCD) 3D printing enables the ...
