Summary: Thickness-tunable PANI/clay nanocomposites were synthesized and characterized. The results showed that the thickness of the nanocomposites can be easily controlled by adjusting the proportions of PANI and clay, and the oxygen barrier properties of the clay can be enhanced by the growth of PANI. Additionally, the intercalation of PANI/clay additives exhibited synergistic anticorrosion properties.

Summary: A spatial view of macroscopic polymer material properties, in terms of nanostructure and irregularities, can help to better understand engineering processes such as when materials may fail. Herein, an integrated messenger material that can report on the material micro- to nanostructure and its processes is introduced. It is based on polymer chains labeled with fluorescent dyes that feature Forster resonance energy transfer (FRET) dependent on chain conformation and concentration within a host polymer material. These FRET materials are integrated within electrospun polystyrene microfibers, and the FRET is analyzed by confocal laser scanning microscopy (CLSM). Changes in FRET are significant when differences in fiber geometries and regularities exist, indicating alterations in polymer conformation and/or concentration in damaged regions of the fibers. This research provides a useful tool for studying material processes and properties at the nano-to-macro level.

Summary: In this study, the effects of doping different acids on the corrosion resistance of polyaniline/epoxy composite coatings were investigated. It was found that the doping acid has a significant influence on the corrosion resistance and passivation performance of the coatings. PANI-SSA/WEP coatings exhibited the highest impedance value and showed significantly enhanced protective performance, which can be attributed to the oxidation-reduction reversibility of PANI-SSA and the inhibition functionality of the released sulfosalicylic acid.
