“…PAEK exhibited a high modulus of 2−2.5 GPa, but a relatively lower elongation at break of less than 4.5%, with the strength ranging from 30.4 to 45.6 MPa. Obviously, the mechanical properties of the shape memory PAEKs (σ = 25−70 MPa) were comparable to those reported, [19][20][21][22][23]25,26,33,55 suggesting that the addition of PEGDA and NVP did not significantly reduce the strength, and were much stronger than PEDGA/NVP hydrogels. 53 The cross-linker PEGDA400/PEGDA600 was pivotal in adjusting the mechanical properties.…”

“…Leng et al achieved thermo- and electric-triggered PAEK with excellent solubility, adjustable transition temperature, and impressive shape memory properties by modulating the variation of bisphenol monomers. Furthermore, the multiple response shape memory effect and extended applications could be realized by incorporating inorganic fillers. − This chemically and physically modified approach greatly enriched the field of shape memory PAEK and demonstrated its potential application as a space-deployable structure, intelligent jet propulsion system, high-temperature sensor, and actuator. − …”

Polyaryletherketone (PAEK), an engineering plastic with exceptional mechanical properties and a high glass transition temperature, can be tailored with various properties to meet the multiple requirements of aerospace applications. However, it remains a challenge to 3D print PAEK with good properties. Herein, a direct ink writing (DIW) 3D printable PAEK ink has been developed, and the yielded PAEK parts possess high tensile strength and excellent shape memory properties. The incorporation of N-vinyl-2-pyrrolidone (NVP) and polyethylene glycol diacrylate PEGDA into PAEK oligomers (PAEKOs) facilitated their versatility as diluents or reactive functional monomers. This characteristic enabled random cross-linking through photoinitiator exposure for the formation of block copolymers, establishing the essential stationary and reversible phases needed for shape memory capabilities. The photocured PAEK demonstrated excellent comprehension performances, including an outstanding tensile strength (42.6 MPa), thermal stability (T d -246 °C), shape fixation ratio (>93%), and shape recovery ratio (>100%). Furthermore, PAEK with a greater shape memory effect was utilized as an actuator to realize gripping and releasing at high temperatures (140 °C). This study therefore provides an emerging strategy to fabricate shape memory components for challenging environments using DIW technology. This approach also holds promise for implementation in systems beyond PAEK which have typically been difficult to print.

A novel smart material is developed, which is synthesized by succinic anhydride, epoxy resin, and zinc acetylacetone hydrate. The smart material has excellent properties of self‐healing, shape memory, and degradation. The experimental results of performance characterization show that the material has good thermal stability. The glass transition temperature is adjustable between 100 and 120°C, and the storage modulus can reach 20 GPa. The maximum thermal expansion at 50°C is less than 15%, the thermal expansion equilibrium time at 120°C is less than 5 min, and the maximum thermal expansion is 131%. The stress relaxation time at 120°C is more than 2 h, which can slowly self‐heal on the basis of maintaining the mechanical strength. When the NaOH content is 1.5%, the degradation equilibrium can be reached in about 3 h, and the maximum degradation rate is 86%. The comprehensive performance evaluation shows that after hot rolling at 120°C/16 h, the material has no effect on the rheology and filtration properties. When plugging the fracture width of 5 × 4 mm, the pressure bearing capacity reaches 10 MPa. Its main mechanism is temperature‐sensitive expansion, and the stress relaxation effect heals and blocks the micro pore throat.

Multiple shape memory polymers (MSMPs), capable of remembering multiple temporary shapes in response to distinct stimuli, hold broad prospects for application. The design of MSMPs generally extends from the concept of dual shape memory polymers, yet innovating methods for their design and preparation remain challenging. In this work, we drew inspiration from the spine and developed an approach for the design and preparation of MSMPs. This approach employs intramolecular hydrogen bonds and resistance among semirigid chains to stabilize all the transition states in situ. The formation of metastable states was used to shape the memory design. Through this strategy, we have synthesized a series of polynorbornene copolymers PNB-mSi-nAc-DCPD (m/n = 3/1, 1/1, or 1/3) with dual-and triple-shape memory effect when subjected to stimuli such as thermal, alcohol/ water, and pH. Furthermore, these copolymers demonstrate superior self-healing, mechanical, and easy processing performance, markedly broadening their potential applications.
