Summary: A series of N-containing hyper-cross-linked polymers were synthesized from different monomers via one-step crosslinking reactions, exhibiting varying porosity, N content, morphology, and hydrophobicity. HCP1 and HCP3 showed good CO2 uptake, while HCP4 and HCP6 demonstrated higher I2 vapor uptake. The results suggest that porosity, especially microporosity, plays a key role in CO2 capture, while chemical structure is more important for I2 vapor adsorption.

Summary: In this study, a hyper-cross-linked polymer was synthesized using conjugated polymers as long and rigid building blocks, resulting in an organogel with a hierarchical porous structure through a click reaction. The organic aerogel derived from the rigid conjugated polymer-based organogel exhibited fast adsorption rate and high adsorption capacity for iodine in both aqueous and gas phases, attributed to the rich pi electrons and aromatic structures of the hyper-cross-linked polymer networks. The capture efficiency for iodine in saturated iodine aqueous solution exceeded 80% within 5 min, and the adsorption equilibrium capacity of 3.28 g g-1 for iodine vapor was achieved within 60 min. Additionally, the iodine-loaded aerogel had excellent retention in air and could be recycled after thermal release.

Summary: The phase influence of molybdenum selenide (MoSe2) on its electromagnetic wave (EMW) absorption performance was investigated. Different phases of MoSe2 were synthesized by controlling the intensity of the reduction process. It was found that 2H/1T-MoSe2 exhibited the best absorption performance, with a minimum reflection loss of -52.3 dB@16 GHz and an effective bandwidth of 6.4 GHz at a thickness of 2.1 nm, covering the entire Ku band. Additionally, a flexible microwave absorbing material with a minimum reflection loss of -33.4 dB@9.1 GHz was created by constructing 2H/1T-MoSe2@RGO layered nanostructures on the surface of cotton fabric, with an effective bandwidth covering the entire X-band at a thickness of 3.3 mm. This work provides important insights for improving the electromagnetic wave absorption performance through phase engineering and proposes a novel idea for the development of fiber-based multifunctional flexible microwave absorbing materials.
