However, PBAT resins are highly flammable and have poor thermal stability and lower compressive strength performance. For enhancing PBAT compressive strength, thermal stability, and flame retardancy performance, polylactic acid (PLA) resin was used to mix with the PBAT matrix. Meanwhile, a biomass additive (PA@CS) was prepared through phytic acid (PA) solution as the grinding medium modifying cellulose (CS) particles by the ball milling process. As the PBAT/10PLA/PA@CS foam presented, PA@CS implanted into pore walls which supported the structure integrity of foams and presented the lowest surface temperature when heating at 170 °C for 180 s. The compressive strength of PBAT/10PLA/PA@CS foam with 5 wt% of PA@CS addition reached 1.05 MPa at 20 % strain. During the combustion process, PA@CS, as flame retardants, demonstrated excellent suppressing heat dispassion and fire-resistance performance. For instance, 5 wt% of PA@CS presented the highest ultimate oxygen index (LOI) (27.9 %), and UL-94 V-0 rating. In detail, 5 wt% of PA@CS also reduced the peak of heat release rate (PHRR) from 851.47 kW m<sup>−2</sup> to 524.45 kW m<sup>−2</sup> by 38 %, total heat release (THR) from 84.34 MJ m<sup>−2</sup> to 66.45 MJ m<sup>−2</sup> by 21 %.

Here, a direct ink writing (DIW) printed high-precision cyanate ester-urethane (CU) shape memory polymer with excellent performance was accomplished by incorporating two dynamic covalent bonds (carbamate and cyanuric acid) through copolymerizing cyanate ester with polyurethane acrylates. During curing, carbamate and cyanuric acid enable stress relaxation and polymer network rearrangement, facilitating the permanent reconfiguration of CU to form a novel triazine network structure. As a result, a high mechanical properties CU with excellent strength (83 MPa) and superior Young's modulus (2.37 GPa) were obtained, besides, the transition temperature (near 250 °C) is the highest in comparison to currently reported 4D-printed shape memory polymers. Furthermore, this reconfigurability was demonstrated by imprinting various surface patterns at microscopic level. Moreover, the reconfigurability of CU provides a novel strategy for smart molds in deformation and easy demolding.
