Summary: The aim of this study was to optimize the preparation of poly(m-aminophenol)/silver nanocomposite and investigate the structure and morphology of the composites. Different morphologies of nanocomposites were obtained using different methods of preparation, with the nanocomposite with a uniform distribution of small silver nanoparticles showing the highest conductivity. These findings provide guidance for the development of nanocomposites for a wide range of applications, including sensors, supercapacitors, and electrode materials.

Summary: The postpolymerization modification of acrylic acid copolymers is demonstrated in this study. A library of functional acrylate polymers was produced by direct addition of polymeric carboxylic acid to allene sulfonamides. Sterically congested methacrylic acid copolymers and acrylic acid copolymers were found to participate in the postpolymerization modification process with good conversions.

Summary: This study introduces a redox-active poly-counterion doping concept to enhance the electrochemical performance of conducting polymers (CPs), especially under ultra-high mass loadings. By doping with poly-counterions, the dopants undergo redox reactions during charge/discharge processes to provide additional capacitance and improve the electrical conductivity of CPs. Additionally, poly-counterions with steric hindrance can act as structural pillars and facilitate ion transport in CPs.

Summary: In this study, poly(butylene adipate-co-terephthalate) (PBAT) was functionalised with itaconic anhydride (IA) via melt grafting. The ratio of IA to dicumyl peroxide (DCP) was found to be crucial for the reaction outcome, and low reagent concentration and conversion resulted in the lowest effective rate constant.

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: By using PAA-catalyzed in-situ COF synthesis method to apply COF-PAA modifier on PVDF membranes, the water flux, rejection rate, and antifouling properties can be improved, with a reduced leaching rate of PAA. The tight bonding of COF to PAA on the membrane surface contributes to enhanced stability and antifouling properties.

Summary: This study systematically varied the feed composition to synthesize polyaniline (PANi) and polyaniline-clay nanocomposites (PACN), and analyzed their thermal properties. The results showed that increasing the oxidant concentration decreased the thermal stability and melting point of PANi, while the reinforcement of PANi with clay increased its thermal stability and melting point. The optimal thermal stability and melting point of PANi were achieved by adding about 0.1 wt% of the oxidant.

Summary: The uniform dielectric permittivity and frequency-dependent ac conductivity of hollow and porous semiconducting copolymer poly(aniline-co-m-hydroxyaniline) (PA-co-m-HA)s were studied using various techniques including electrochemical impedance spectroscopy, electronic spectroscopy, X-ray diffraction, and cyclic voltammetry. The copolymer exhibited globular and porous morphology, reduced crystallinity, and blue-shift in optical spectra.
