General description

Hexamethyldisilazane (HDMS) is a bulk organo silicon compound.It finds major application as a silanizing agent, silylation with HMDS is carried out in the presence of an acid catalyst.The hydrophobic nature of HDMS coatings on various nanoparticles renders them resistant to water contamination and flocculation′s, during synthesis.

Application

It has been used as a
  • modifier to control the shape, formation of agglomerates,surface area and pore size of silica particles.
  • precursor for the depositing of SiNx on diamond like carbon films.
  • protective hydrophobic coating for nanoparticles.

This paper describes the synthesis and surface engineering of core/shell-type iron/iron oxide nanoparticles for magnetic hyperthermia cancer therapy. Iron/iron oxide nanoparticles were synthesized from microemulsions of NaBH(4) and FeCl(3), followed by surface modification in which a thin hydrophobic hexamethyldisilazane layer...
