Radical-mediated Reactions in Sulfur containing Photopolymers

This thesis explores light-triggered, sulfur-centred reactions in cross-linked polymers to advance shape-memory materials and membrane technology. Whereas conventional shape-memory materials remember a shape to which they revert when prompted, here we describe a 3D-printable photopolymer system capable of “forgetting” its original shape upon UV irradiation. Additionally, a light-based membrane fabrication process enabled continuous defect-free films on porous supports, overcoming conventional speed–control trade-offs. The approach was further extended to photopatterned surfaces with potential antifouling relevance. Together, the work establishes light-controlled sulfur chemistry as a powerful strategy for adaptive polymers and controlled membrane-relevant film formation.
