[Journal of Materials Chemistry C]Constructing fully carbon-based fillers with a hierarchical structure to fabricate highly thermally conductive polyimide nanocomposites
Abstract： A novel kind of fully carbon-based filler (f-MWCNT-g-rGO) is constructed by a reaction between melted urea functionalized multi-walled carbon nanotubes (f-MWCNTs) and graphene oxide (GO) followed by chemical reduction. The corresponding highly thermally conductive polyimide (f-MWCNT-g-rGO/PI) nanocomposites are then fabricated through the combined method of in situ polymerization, ele...

【Materials Reports】Facile preparation of polypeptides:moisture insensitive and superfast ring opening polymeriz
Abstract:
Polypeptides with excellent biocompatibility，bioactivity and bio-degradability have been widely used in drug and gene delivery, tissue engineering，protein mimicking, antibacterial and other biomaterial applications. It has been more than 110 years. since Hermann Leuchs discovered N-carboxyanhydrides (NCA, also called Leuchs anhydride) for the first time in 1906.Ever since that ...

Electrochemical deposition of γ-MnO2 on Ag/rGO hybrid films as flexible electrode materials for asymmetric supercapacitor
The flexible electrodes are the essential components for fabricating modern flexible supercapacitors (SCs). In this study, a composite hybrid film integrated with silver nanoparticles (Ag NPs), reduced graphene oxide (rGO) and γ-MnO2 nanorods as a flexible electrode has been developed by the electrochemical deposition method. The substrate (rGO) of the electrode not only provides mechanical sta...

Sum Frequency Generation Vibrational Spectroscopy Using Evanescent Waves—Toward Probing Irregular and Complex Surfaces of Mesoscopic-Scale Materials
With the rapid development of materials science, on-demand techniques are highly needed with the capability to characterize materials in the micrometer and nanometer scales. In this work, we show that, by employing a prism geometry, total internal reflection sum frequency generation (SFG) vibrational spectroscopy allows for characterizing mesoscopic materials with irregular or complex surfa...

[Solar Energy Materials and Solar Cells]Construction of nanowire CH3NH3PbI3-based solar cells with 17.62% efficiency by solvent etching technique
1D Nanowire CH3NH3PbI3 thin films have been successfully constructed by solvent etching technique. The etching solution was consisted of a small amount of polar solvent in non-polar solvent, and the roughness of the film can be precisely controlled by the adding amount of polar solvent. A best and repeatable PCE of 17.62% was achieved from the CH3NH3PbI3-based solar cells device with nanowire fi...

【RSC Advances】Facile synthesis of hierarchically porous carbonaceous materials derived from olefin/ aldehyde precursors using silica as templates
Porous carbon is exceptionally useful, but it remains a great challenge to develop a facile route to prepare porous carbon materials with hierarchical structure and enhanced porosity. This work demonstrates a novel synthetic pathway for hierarchical carbonaceous materials (HCM) using isobutene and formaldehyde as carbon precursors via silica templates impregnated with phosphorus. Different from ...

【Materials Letters】Tunable field emission properties of carbon nanotube arrays by engineering Fe catalysts
High-quality carbon nanotube (CNT) arrays composed of nanotubes with different diameters and wall numbers were synthesized by water-assisted chemical vapor deposition (CVD) from engineered Fe catalysts. Interestingly, the distribution of nanotube diameter and wall number broadened over 2.5 times as the catalytic Fe thickness increased. The mean diameter and wall number of nanotubes increased mon...

【Journal of Materials Science】Electromagnetic and microwave absorbing properties of magnetite nanoparticles decorated carbon nanotubes/polyaniline multiphase heterostructures
Magnetite nanoparticles decorated CNTs/PANI multiphase heterostructures were prepared by polymerization of aniline monomer and an additional process of the coprecipitation of Fe2+and Fe3+. Scanning electron microscopy and transmission electron microscopy observation indicated that the monodispersed magnetite nanoparticles were uniformly decorated on the surface of CNTs/PANI. The formation of mag...
