Elastic carbon foam via direct carbonization of polymer foam for flexible electrode and organic chemical adsorption
关键字：Elastic carbon foam, polymer foam, flexible electrodes
Commonly, commercially available carbon foam derived from polymers shows brittle characteristics. In this paper, the concept of preparing an elastic carbon foam via the direct carbonization of a polymer foam is presented. A novel carbon foam with a 3D elastic interconnected network was prepared by the direct carbonization of melamine foam. The as-prepared carbon foam exhibited characteristics incl...

05 Electrochemical characteristics of discrete, uniform, and monodispersed hollow mesoporous carbon spheres in double-layered supercapacitors
关键字：nanostructures, chemical vapor deposition, mesoporous materials, silica, supercapacitors
Core-shell‐structured mesoporous silica spheres were prepared by using n-octadecyltrimethoxysilane (C18TMS) as the surfactant. Hollow mesoporous carbon spheres with controllable diameters were fabricated from core-shell‐structured mesoporous silica sphere templates by chemical vapor deposition (CVD). By controlling the thickness of the silica shell, hollow carbon spheres (HCSs) with different di...

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...
