| titleOfInvention | Low-cost preparation method of large-size SiC nanowire aerogel |
| abstract | The invention discloses a low-cost preparation method of a large-size SiC nanowire aerogel, which comprises the steps of taking green and cheap starch as a carbon source, taking metal silicon as a silicon source, taking water as a solvent, adding a proper amount of foaming agent, carrying out sol, foaming, gel curing, carbonization and in-situ reaction to generate SiC nanowires, and interweaving and interconnecting the nanowires to obtain the SiC nanowire aerogel. After starch is dissolved in water to form sol, a large-size and high-porosity porous carbon blank is formed after gel curing and carbonization, a carbon source is provided for silicon-carbon reaction, and a space and a template are provided for SiC nanowire growth; with the progress of silicon-carbon reaction, the carbon net is continuously consumed, and simultaneously, SiC nanowires are generated in large quantity and are mutually crosslinked to obtain the large-size SiC nanowire aerogel. The method not only greatly reduces the manufacturing cost, but also solves the technical problem that the aerogel is difficult to prepare large-size products, and promotes the application of the SiC nanowire aerogel in the industrial fields of heat insulation, catalysis, filtration and the like. |
