219. Porous graphene–carbon nanotube hybrid paper as a flexible nano-scaffold for polyaniline immobilization and application in all-solid-state supercapacitors.
Polyaniline (PANI) has been recognized as an ideal candidate for electrode materials in supercapacitors. However, the relatively low electrical conductivity and poor cyclic stability severely limit its potential applications. Therefore, a proper substrate with carefully designed nanostructures for PANI immobilization is highly desirable for realizing its full performance. In this study, three-dime...

217. Electrospun polymer nanofiber membrane electrodes and an electrolyte for highly flexible and foldable all-solid-state supercapacitors.
A sandwiched symmetric all-solid-state supercapacitor consisting of flexible electrospun polyaniline (PANI)/carbonized polyimide (CPI) nanocomposite membrane electrodes and a poly(vinyl alcohol) (PVA)/poly(acrylic acid) (PAA) nanofiber membrane-reinforced PVA/H3PO4 gel separator has been successfully fabricated. Needle-like PANI nanoparticles are vertically formed on the high electrically conducti...

Probing the Nanostructure, Interfacial Interaction and Dynamics of Chitosan-Based Nanoparticles by Multiscale Solid-State NMR
Chitosan-based nanoparticles (NPs) are widely used in drug and gene delivery, therapies and medical imaging, but a molecular-level understanding of the internal morphology and nanostructure size, interface and dynamics, which is critical for building fundamental knowledge for the precise design and efficient biological application of the NPs, remains a great challenge. Therefore, the availability ...

Copolymerization of poly (vinyl alcohol)-graft-poly (1, 4-dioxan-2-one) with designed molecular structure by a solid-state polymerization method
Poly(vinyl alcohol)-graft-poly(1,4-dioxan-2-one) (PVA-g-PPDO) with designed molecular structure was synthesized by a solid-state polymerization. The solid-state copolymerization was preceded by a graft copolymerization of PDO initiated with PVA as a multifunctional initiator, and Sn(Oct)(2) as a coininitiator/catalyst in a homogeneous molten state. The polymerization temperature was then decreased...

195. One-step synthesis of graphene nanoribbon–MnO2 hybrids and their all-solid-state asymmetric supercapacitors.
Three-dimensional (3D) hierarchical hybrid nanomaterials (GNR–MnO2) of graphene nanoribbons (GNR) and MnO2 nanoparticles have been prepared via a one-step method. GNR, with unique features such as high aspect ratio and plane integrity, has been obtained by longitudinal unzipping of multi-walled carbon nanotubes (CNTs). By tuning the amount of oxidant used, different mass loadings of MnO2 nanopart...

Critical Effect of Segmental Dynamics in Polybutadiene/Clay Nanocomposites Characterized by Solid State 1H NMR Spectroscopy
The segmental dynamics of rigid, intermediate, and mobile molecular components in carboxyl terminated polybutadiene (CTPB)/organo?clay (C18?clay) systems was characterized by fully refocused 1H NMR FID. In addition, 1H DQ NMR experiments allowed semiquantitative monitoring of changes in segmental dynamics near the interface. Both methods suggest a critical concent...

Reversible Cross-linking, Microdomain Structure and Heterogeneous Dynamics in Thermal Reversible Cross-linked Polyurethane as Revealed by Solid-State NMR
Polyurethane material is widely utilized in industry and daily life due to its versatile chemistry and relatively handling ease. Here, we focused on a novel thermal reversible cross-linked polyurethane with comprehensive remarkable mechanical properties as reported in our recent work (Adv. Mater. 2013, 25, 4912). The microphase-separated structure and heterogeneous segmental d...

Molecular Dynamics and Crystallization Precursors in Polylactide and Poly(lactide)/CNT Biocomposites in the Insulating State
European Polymer Journal 2013, 49(12), 4008-4019
ABSTRACT:
The early stages of the cold crystallization process and the formation of a rigid amorphous phase as seen by the dielectric response of polylactide, PLA, and composites polylactide/carbon nanotubes, PLA/CNT, are studied here by broadband dielectric spectroscopy for CNT concentrations below percolation. The ...

Tuning Solid-State Fluorescence of a Twisted π - Conjugated Molecule by Regulating the Arrangement of Anthracene Fluorophores
1-(5-(Anthracen-9-yl)-3-(4-methoxyphenyl)-4,5-dihydropyrazol-1-yl)ethanone was synthesized and crystallized to provide three types of crystals with different fluorescent colors and host–guest structures. Crystal structure analysis reveals that this compound possesses twisted π-conjugated structure and different degrees of distortion depending on guest molecules in the three crystal structures. T...
