Summary: Carbon nanotubes (CNTs) reinforced with bismaleimide (BMI) show great potential in space exploration. However, the atomic-level effects of radiation on CNTs are not well understood. Through our study on interacting nanohole defects in model systems of radiation-treated, flattened CNTs, we found that covalent cross-linking improves load transfer, while nanoholes reduce mechanical properties but provide favorable sites for cycloaddition reactions. Our findings can inform mesoscopic models of irradiated CNTs.

Summary: This study prepared seven types of polyimides (PIs) incorporating a chiral isosorbide (ISS) skeleton in the main chain (ISS-PIs), which exhibited excellent optical transparency, low refractive indices, and low dielectric constants compared to wholly aromatic PIs. The bulky alicyclic ISS structure and the bent and flexible PI main chains with reduced intermolecular interactions contributed to the optical properties of ISS-PIs.

Summary: Organosulfur polymers derived from elemental sulfur via the inverse vulcanization process are a new and important class of macromolecules. However, the mechanism of inverse vulcanization and structural characterization of high-sulfur-content copolymers remain challenging. In this study, comprehensive structural characterizations were performed on poly-(S-r-DIB), revealing the incorrect assumptions about its repeating units and the significantly more complex polymerization mechanism.

Summary: A non-covalent compatibilization approach was utilized to prepare polypropylene composites containing expanded graphite and graphene nanoplatelets. Functionalizing the PP matrix with Py moieties facilitated the dispersion of EG and GNPs, with improved aspect ratios of the platelets. Electrical percolation thresholds were around 6% and 10%, with a maximum electrical conductivity achieved of 10(-1) S/m.

Summary: Recent studies have investigated aromatic polyimide (PI) derivatives as redox-active electrode materials for Li-ion batteries due to their high thermal stability, excellent solvent resistance, and good electrical properties. Two PI derivatives, TPA-NTCPI and TPA-PMPI, synthesized from a newly developed DiCN-TPA monomer, show promising electrochemical performance with stable specific capacities up to 1000 cycles for the cathode and high specific capacities up to 1600 mAh g(-1) for the anode after 100 cycles. These results suggest that TPA-NTCPI and TPA-PMPI could be potential organic electrode materials for next generation Li-ion batteries.

Summary: Researchers have developed a simple one-step approach to embed a faradaic material (layered double hydroxide - LDH) in electrochemically exfoliated graphite, resulting in high areal capacitance and energy density. The capacitance was attributed to the exfoliation of graphite and deposition of LDH, while the energy density was achieved through the combination of LDH and graphite.
