Improving Performance of Polymer Photovoltaic Devices Using Annealing-free Approach via Constructing Ordered Aggregations in Solution
Low crystalline order has been proved to be one of the main hindrances for achieving high performance devices based on thin films composed of crystallizable polymer. In this work, we use a facile method to substantially improve crystallinity of poly(3-hexylthiophene) (P3HT) in its pure or composite film via the construction of ordered precursors in the solution used for thin film de...

High-Performance Electrocatalysts for Oxygen Reduction Based on Nitrogen-Doped PorousCarbon from Hydrothermal Treatment of Glucose and Dicyandiamide
A synthetic method was developed for the preparation of Ndoped
porous carbon through hydrothermal treatment at controlled
temperatures by using glucose and dicyandiamide as
precursors and ZnCl2 as an activation reagent. Nitrogen doping
was quantitatively determined by using XPS measurements
and identified in the forms of pyridinic, pyrrolic, graphitic, and
pyridinic N+Onitrogen atoms. Further st...

High performance filtration nanofibrous membranes based on hydrophilic poly(vinyl alcohol-co-ethylene) copolymer
A novel high performance hydrophilic poly(vinyl alcohol-co-ethylene) (PVA-co-PE) nanofibermembrane for filtration
media was prepared and characterized in this study. The PVA-co-PE nanofibers for the membrane preparationwere
fabricated based on a high throughput, cost effective and environmental friendlymethod developed
by us. The basic properties of PVA-co-PE nanofibrous membrane and commercially ...

Insights into the surface property and blood compatibility of polyethersulfone/polyvinylpyrrolidone composite membranes: toward high-performance hemodialyzer
Applications of blood purificationmembranes are fuelled by diverse clinical needs, such as hemodialysis, hemodiafiltration, hemofiltration, plasmapheresis, and plasma collection. For clinical usage, the adding of polyvinylpyrrolidone (PVP) is the general protocol for the design of antifouling and antithrombotic properties integrated artificial membranes. In the present work, to insigh...

215. High-performance flexible supercapacitors based on mesoporous carbon nanofibers/Co3O4/MnO2 hybrid electrodes.
In this work, self-standing Co3O4 doped CNF (CNFs/Co3O4) membranes were prepared through a facile sol–gel electrospinning and high-temperature carbonization process, followed by a subsequent in situ redox reaction in KMnO4 solution to obtain mesoporous MnO2 sheets coated CNFs/Co3O4/MnO2 composite membranes. The as-fabricated flexible CNFs/Co3O4/MnO2 membrane electrodes exhibit superior capacitive...

213. Flexible free-standing 3D porous N-doped graphene–carbon nanotube hybrid paper for high-performance supercapacitors.
The nanoarchitecture of carbon with assembled building blocks on diverse scales is of great importance for energy storage. Herein, we demonstrate high-performance supercapacitors by building a three-dimensional (3D) porous structure that consists of a N-doped graphene–carbon nanotube (CNT) hybrid. The 3D porous nitrogen-doped graphene–CNT (p-N-GC) hybrid paper was fabricated by using polystyrene...

Phosphorus–, nitrogen- and carbon- containing polyelectrolyte complex: preparation, characterization, and its flame retardant performance on polypropylene
A new polyelectrolyte complex (PEC), containing phosphorus, nitrogen and carbon elements, has been prepared from positively charged polyethylenimine and negatively charged phytic acid. The PEC shows good performance on improving the thermal stability and flame retardancy of polypropylene (PP). When the content of PEC is 20 wt %, the char residues at 600 oC for the PP/PEC composites (PP/20PEC) is 1...

Hemocompatibility and ultrafiltration performance of surface-functionalized polyethersulfone membrane by blending comb-like amphiphilic block copolymer
While polyethersulfone (PES) represents outstanding oxidative, thermal and hydrolytic stability as well as good mechanical and film-forming properties, the hemocompatibility of PES membrane must be dramatically enhanced to reduce injections of anticoagulants during hemodialysis.

A hierarchical porous carbon membrane from polyacrylonitrile/polyvinylpyrrolidone blending membranes: Preparation, characterization and electrochemical capacitive performance
Novel hierarchical porous carbon membranes were fabricated through a simple carbonization procedure of well-defined blending polymer membrane precursors containing the source of carbon polyacrylonitrile (PAN) and an additive of polyvinylpyrrolidone (PVP), which was prepared using phase inversion method. The as-fabricated materials were further used as the active electrode materials for su...

210. Enhanced visible-light photocatalytic performance of electrospun carbon-doped TiO2/halloysite nanotube hybrid nanofibers.
In this work, the effects of halloysite nanotubes (HNTs) on the visible-light photocatalytic ability of electrospun carbon doped TiO2/HNT (CATH) nanofibers have been explored. Structural and morphological investigations demonstrate that incorporation of HNTs into anatase CATH hybrid nanofibers was easily achieved by using sol–gel processing combined with electrospinning approach, thus HNTs could ...
