Fabrication and structure of carbon aerogel spheres prepared by inverse suspension/emulsion polymerization and ambient pressure drying

Journal of Applied Polymer Science (2007)

Ning Liu Shuting Zhang Ruowen Fu M. S. Dresselhaus G. Dresselhaus

Abstract Carbon aerogel (CA) spheres were fabricated by inverse suspension polymerization of an emulsified resorcinol–formaldehyde aqueous solution with a basic surfactant used as catalyst, and then drying by gradually heating the resultant sol–gel spheres at ambient pressure. The fabrication conditions, nanostructures of the resultant CA spheres, and their electrochemical properties were investigated. By controlling the time at which stirring started, the stirring speed, and the recipe of the emulsion solution, the diameter of the CA spheres can be controlled from 70 to 1000 μm. The internal carbon nanoparticles of the spheres are of a size ranging from 20 to 40 nm, and are interconnected into a three‐dimensional network. The highest surface area and mesopore volume of the spherical CAs thus prepared reach 626 m 2 /g and 0.69 cm 3 /g, respectively. These CAs can be used as an electrode in supercapacitors, and the specific capacitance is as high as 197 F/g. © 2007 Wiley Periodicals, Inc. J Appl Polym Sci 2007

Synthesis and Characterization of Copper-Doped Carbon Aerogels

Langmuir (2002)

Theodore F. Baumann Glenn A. Fox Joe H. Satcher Noriko Yoshizawa Ruowen Fu

We have prepared carbon aerogels (CAs) doped with copper through sol−gel polymerization of formaldehyde with the potassium salt of 2,4-dihydroxybenzoic acid, followed by ion exchange with Cu(NO3)2, supercritical drying with liquid CO2, and carbonization at 1050 °C under a N2 atmosphere. The materials were characterized by elemental analysis, nitrogen adsorption, high-resolution transmission electron microscopy, and X-ray diffraction. Results obtained indicate that this approach is an effective method for controlling both the amount and the distribution of a desired metal species within the carbon framework. We also found that carbonization of the copper-doped organic aerogels results in the formation of spherical copper nanoparticles within the carbon framework of the aerogel. The copper nanoparticles have a cubic crystalline structure and range in size from 10 to 50 nm. The Cu-doped CAs retain the overall open cell structure of metal-free CAs, exhibiting high surface areas and pore diameters in the micro- and mesoporic region.

Facile and Universal Defect Engineering Toward Highly Stable Carbon‐Based Polymer Brushes with High Grafting Density

Small (2023)

Zelin Wang Xidong Lin Youchen Tang Dongtian Miao Junlong Huang

Abstract Carbon‐based polymer brushes (CBPBs) are an important class of functional polymer materials, which synergistically combine the advantageous properties of both carbons and polymers. However, the conventional fabrication procedures of CBPBs involve tedious multistep modification, including preoxidation of carbon substrates, introduction of initiating groups, and subsequent graft polymerization. In this study, a simple yet versatile defect‐engineering strategy is proposed for the efficient synthesis of high‐grafting‐density CBPBs with highly stable CC linkages via free radical polymerization. This strategy involves the introduction and removal of nitrogen heteroatoms in the carbon skeletons via a simple temperature‐Fmed heat treatment, leading to the formation of numerous carbon defects (e.g., pentagons, heptagons, and octagons) with reactive C=C bonds in the carbon substrates. The as‐proposed methodology enables the facile fabrication of CBPBs with various carbon substrates and polymers. More importantly, the highly grafted polymer chains in the resulting CBPBs are tethered with the carbon skeletons by robust CC bonds, which can endure strong acid and alkali environments. These interesting findings will shed new light on the well‐orchestrated design of CBPBs and broaden their applications in various areas with fascinating performances.
