However, the high solubility of these materials in electrolytes and their inherently low conductivity have limited their electrochemical performance. Herein, this work presents an effective strategy to assemble the hyper-cross-linked polymer (CuTPP-PMDA-HCP) by integrating copper tetraphenylporphyrin with pyromellitic dianhydride. CuTPP-PMDA-HCP not only mitigates the dissolution of organic species into the electrolyte but also enhances its overall conductivity. As expected, CuTPP-PMDA-HCP exhibits a remarkable reversible capacity of 266.5 mA h g^–1 at 0.2 A g^–1, excellent cycle rate capability, and robust cycling performance (101 mA h g^–1 after 1200 cycles at 5 A g^–1). Meanwhile, the mechanism of the CuTPP-PMDA-HCP cathode serving as double redox-active centers for hosting both anions (PF₆^–) and cations (Li⁺) in typical dual-ion organic batteries is investigated by comprehensive experimental analysis and density functional theory calculations.

Sustainability challenges are (i) the maximized use of unavoidable postindustrial waste, due to the need of a structural support during processing, and (ii) the introduction of biobased materials such as PA11 compared to conventional PA12. In the present work, in the first part, the performance of virgin, vacuum-aged, and air-aged PA11 and PA12 powders is compared, analyzing molecular, thermal, rheological, and mechanical properties. While the (overall) thermal (th) decomposition rate coefficient is almost equal for both polymers (<i>k</i>_Mp,th of 2.0 × 10^–6 and 2.4 × 10^–6 s^–1; <i>M</i>_p; peak average molar mass), PA12 is more prone to oxidative (ox) degradation (<i>k</i>_Mp,ox,PA11 of 3.2 × 10^–7 s^–1 vs <i>k</i>_Mp,ox,PA12 of 4.6 × 10^–6 s^–1), although PA11 has more discoloration at the surface. In a second part, it is shown that the incorporation of (PA11) postindustrial waste powder can be considered during printing, with even better mechanical properties possible upon applying vacuum treatment, in case the impact strength is less critical. With air treatment, a strong drop in the performance is obtained due to (imide-driven) microphase separation and scission-driven molecular degradation, the latter enlarged if one isolates the influence of 2-pyrrolidone and triethylene glycol, the main components of the chemical agents.

Severe ester exchange reactions, evidenced by yellowing and attenuated ester characteristic peaks, were observed in blends with varying ratios, leading to deteriorated PBT crystallinity.

Nonisocyanate polyurethanes (NIPUs) offer a safer, more sustainable alternative, aligning with EU regulations and climate goals. In this work, we report an eco-friendly method for producing thermosetting NIPU foams with tailored properties and humidity-responsive shape memory using supercritical CO₂ as a physical blowing agent. This innovative approach not only replaces current flammable, greenhouse-gas-emitting agents with high global warming potential but also revalorizes CO₂ in the manufacturing and synthesis process. The method involves CO₂ pressure-induced absorption, temperature-induced desorption, and curing of five-membered cyclic carbonate/amine resins. At elevated temperatures, simultaneous CO₂ release and NIPU cross-linking drive cellular structure formation. We studied the effects of curing agents, foaming/curing temperatures, and the impact of stabilizers on the final foam properties. The resulting foams demonstrated tunable densities (270–451 kg/m³), compression moduli (16–350 kPa), and cell sizes (0.33–0.99 mm). Notably, these NIPU foams also exhibited humidity-triggered shape memory behavior, which can greatly expand their functionality.

However, the performance of conventional hydrogel systems often deteriorates under harsh conditions such as elevated temperatures and high salinity. To overcome this limitation, we developed a hydrogel with exceptional stretchability and resilience by integrating phenyl nanospheres (PNSs) as nanocross-linkers within polyampholyte chains. The PNSs were synthesized through precipitation polymerization of divinylbenzene in a water/ethanol solvent. P(AM-AMP-DAD)_PNS gels were fabricated by copolymerizing acrylamide (AM) with equimolar amounts of 2-acrylamido-2-methylpropanesulfonate sodium (AMPS-Na) and diallyl dimethylammonium chloride (DADMAC), utilizing PNSs as cross-linkers. This unique structure achieved a remarkable breaking elongation of 920% at 100 kPa and exhibited no fractures after five cycles at 400% strain. Hydrophobic interactions among PNSs created dynamic association domains, enabling reversible energy dissipation and improving mechanical robustness. The antipolyelectrolyte effect of the polyampholyte chains provided exceptional fracture resistance in ultrahigh-salinity environments. The swelling ratio of P(AM-AMP-DAD)_PNS gels remained stable and even slightly increased in formation water, particularly at 130 °C, where it was 1.2 times higher than at room temperature. Furthermore, this hydrogel demonstrated long-term stability under extreme conditions (130 °C, 2.2 × 10⁵ mg L^–1 salinity, Ca²⁺ + Mg²⁺ = 1.3 × 10⁴ mg·L^–1) for up to 60 days. Core-flooding tests revealed that the fractured core, treated with P(AM-AMP-DAD)_PNS particles and subjected to high-temperature aging, achieved a breakthrough pressure exceeding 6 MPa, with a plugging efficiency of 99.93%.
