Soft-templated Synthesis of Carbon Micron-Buds

Abstract

Using coal tar pitch based amphiphilic carbonaceous materials (ACMs) as the precursor and amphiphilic triblock copolymer F127 as the only soft template, hollow Carbon Micro-Buds (CMBs) were synthesized. The concentration of F127, cF, and the mass ratio of F127 to ACM, r, are the key parameters of controlling the shape of the asprepared products. CMBs with diameters of about 1 μm were prepared under the condition of ci = 53.4 g/L and r = 2. CMBs were amorphous materials.
