Preparation of Fluorescent Conjugated Polymer Films with Different Emission Colors: Investigation into the Influences of Chemical Structure and Morphology
关键字：chemical structures，conjugated polymers，films，fluorescence，morphology
A series of PPV fi lms with different fl uorescent emission colors are prepared using a facile approach. Modifi ed from the conventional Wessling route, the labile sulfonium groups in the polymer precursor (pre-PPV) are partly substituted to various degrees by relatively stable methoxy groups, followed by a regular thermal elimination step to obtain PPV. Different chemical structures among these...

28. A simple approach for preparing transparent conductive graphene films using the controlled chemical reduction of exfoliated graphene oxide in an aqueous suspension
We report a simple method for preparing transparent conductive graphene films using a chemically converted graphene (CCG) suspension that was obtained via controlled chemical reduction of exfoliated graphene oxide (GO) in the absence of dispersants. Upon thermal annealing of the CCG films, the films displayed a sheet resistance on the order of 103 Ω·0-1 at 80% transparency (550 nm), with...

70. [Chemical Engineering Journal] Robust and flexible strain sensors based on dual physically cross-linked double network hydrogels for monitoring human-motion
Soft, stretchable, and elastic hydrogels have recently attracted immense interest due to their potential applications
in wearable strain sensors. However, most of hydrogel-based sensors exhibit poor mechanical properties.
Here, a robust, flexible and strain-sensitive conductive wearable sensor is prepared based on dual physically
cross-linked double network hydrogels consisting of core-...

【76 Chemical Engineering Journal】Selective Preparation of Biomass-Derived Porous Carbon with Controllable Pore Sizes toward Highly Efficient CO2 Capture
This work reports a selective chemical activation method for the controllable synthesis of porous carbons with pore sizes ranging from micropores to hierarchical micro/mesopores from date sheets. Through selectively controllable carbonization and combined activation processes, the as-prepared carbon materials exhibit a high specific surface area (3337 m2/g) mainly derived from ultra-micropores i...

Simultaneously Porous Structure and Chemical Anchor: A Multifunctional Composite by One-Step Mechanochemical Strategy towards High-Performance and Safe Lithium-Sulfur Battery
lithium-sulfur (Li-S) battery has been regarded as one of most promising energy-storage systems to meet requirements for high-energy-density in electric vehicles, advanced portable electronic devices, and so on. However, practical application of Li-S battery is restricted severely by easy dissolution of lithium polysulfides and high ?ammability of sulfur. Herein, we developed, for the first time, ...
