Summary: This study describes the synthesis of hexameric macrocyclic aniline (MA[6]) and its assembly into conductive organic wires. The electrical conductivity of ESMA[6] is high and responsive to acid-base conditions. The crystal structure of ES-MA[6] reveals the formation of trimeric units and nanotubes with regular channels, providing a potential route for synthetic nanotubes used in ion or small molecule transport. Spectroscopic analysis further demonstrates the interconversion between acidic and basic forms of the macrocycles and how charge carriers are formed through protonation, resulting in high electrical conductivity.

Summary: Modifying the electronic properties of conductive polymers is crucial for the development of environmentally friendly and efficient energy storage devices, sensors, transistors, solar cells, etc. The electronic structure of conductive polymers plays a significant role in determining their performances and application areas. This study focuses on the electronic structures of polypyrrole, polythiophene, and polyaniline conductive polymers, and examines the effects of pH modification on these polymers. The chemical structure of the dopant-anion and the conjugation length of the polymer chain are found to be key factors influencing the electronic properties of conductive polymers.

Summary: In this paper, the densification mechanics of polymeric syntactic foams under compressive loading are investigated using computational models and regression analysis. It is found that microballoon crushing strength and volume fraction have the highest influence on densification stress and energy, while interfacial bonding has the least impact. In addition, the design aspects of syntactic foams with specific overall density are discussed by mapping microballoon volume fraction and wall thickness.

Summary: A simple and feasible method was described to design lightweight, highly electrically conductive, and cost-efficient PLA/CNT foams, using nucleophilic ring-opening reaction of epoxy-based acrylic/styrene copolymer and PLA to induce branched PLA resin. The resulting foam had low density, high crystallinity, and improved conductivity due to enhanced CNT orientation induced by cell growth in the BPLA matrix. This proposed foaming material provides a way for designing and preparing high-performance CNT products.

Summary: The utilization of polyaniline as a linker to anchor nickel sulfide (NiS2) on the surface of graphene oxide (GO) with a hollow bowl-like structure leads to a unique material (NiS2@15PG) with enhanced electrical conductivity and ion diffusion properties. This modification significantly improves the charge transfer resistance and Warburg impedance of NiS2. The resulting NiS2@15PG exhibits high specific capacitance and excellent multiplicativity, making it a promising material for practical applications in supercapacitors.

Summary: This study investigated the variation of cell structure in multilayered PS/PMMA foams with increasing layer numbers. Three types of cell structures were observed as the layer number increased: alternating big-cell/small-cell layers, alternating foam/film layers, and almost uniform cell structure. The thickness of the layers was identified as a crucial factor in determining the formation and variation of the cell structure.

Summary: In this study, a novel type of D-A non-fused-ring copolymers was designed and synthesized to overcome the trade-off relationship between electrical conductivity and Seebeck coefficient in organic semiconductors. The incorporation of fluorine atoms into the polymer backbone effectively increased the ordered degree of molecular stacking and improved both the electrical conductivity and Seebeck coefficient. The bimodal orientation of polymers played a crucial role in decoupling the correlation between electrical conductivity and Seebeck coefficient.

Summary: This research focuses on the versatile substance, polyaniline/layered double hydroxide (PANI@Nd-Co/LDH), under solvothermal conditions. A thorough analysis of its structure and morphology was conducted using various analytical methods. The findings showed that PANI@Nd-Co/LDH exhibited highly sensitive and specific fluorescence detection of Pb(II) and Al(III), outperforming other heavy metal ions. The sensor demonstrated a turn-off fluorescence response for Pb(II) ions and a turn-on fluorescence response for Al(III) ions. The minimum detectable limits (MDL) were determined to be 9.6 nM for Pb(II) and 220 nM for Al(III). PANI@Nd-Co/LDH could be easily regenerated and reused for multiple cycles. The detection mechanisms involved the inner filter effect (IFE) for Pb(II) and the chelation-enhanced fluorescence (CHEF) effect for Al(III). These results highlight the excellent potential of PANI@Nd-Co/LDH in the detection and recognition of Pb(II) and Al(III) ions.
