4.Introduction of N-Octadecylsilane:

5.Synthesis method:

Regarding the synthesis method of octadecylsilane, the literature mentions the research progress of using metal nanomaterials to catalyze the polymerization of long-chain alkylsilane to synthesize polysiloxane.

For example, precious metal nanoparticles of gold can directly catalyze the monomer C18H37SiH3, and polysiloxane nanowires, nanofilaments, and nanotubes were obtained in the reflux digestion experiment of octadecylsilane and a small amount of water.

In this process, when the three Si-H in C18H37SiH3 contact the catalyst surface, Si-H breaks and Au-Si bonds are generated at the same time. Since the Au-Si bond is very weak, it is easily attacked by water molecules to further generate RSi(OH)x, which then polymerizes with each other to form Au/polysiloxane hybrid products.

In addition, nanosilver particles have also been used to catalyze the polymerization of C18H37SiH3 to obtain polysiloxane/nanosilver particle hybrid microspheres.
