High-temperature shape memory photopolymer with intrinsic flame retardancy and record-high recovery stress

• A mechanically robust high-temperature shape memory photopolymer is reported. • The glass transition temperature can reach 280 °C after thermally post-curing. • The HTSMP possesses record-high recovery stress and energy output. • Synergy between isocyanurate and phosphine oxide contributes to high flame-retardancy. • The HTSMP is available for high-resolution digital light printing. Here we report an intrinsically flame-retardant...
