Summary: Conductive polymer polypyrrole (PPy)-coated lithium-rich manganese-based Li1.2Mn0.54Ni0.13Co0.13O2 (LMNCO) nanotube cathode materials were successfully synthesized using electrospinning and vapor-phase polymerization. The PPy coating, with a thickness of about 2 nm, did not alter the morphologies or structures of the LMNCO nanotubes, as confirmed by XRD, SEM, and HRTEM analysis. The electrochemical performance of the PPy-coated LMNCO nanotubes showed significant improvement, displaying a discharge capacity of 200.1 mAh g(-1) and a capacity retention of 99% after 120 cycles at 1 C rate. These enhancements were attributed to the inhibition of side reactions and the protective function of the tubular structure provided by the PPy coating layer. Moreover, the rate capability was also enhanced at high current density due to the increased electronic and ionic conductivity.

Summary: This study investigates the relationship between the morphology of PMMA monopolymers and PMMA-PHEMA copolymers with the expected nature of surfactant-free microemulsions (SFMEs) before polymerization. It is found that previously mesostructured, surfactant-free mixtures can produce porous polymers of different morphologies, while unstructured, oil-rich regions lead to solid, transparent polymers without nanostructured morphologies. Additionally, a surfactant-based reference system shows similar phase behavior and polymer morphologies as the comparable surfactant-free system, indicating the importance of the hydrotropic behavior of HEMA in this system.
