Description

Application

HDMS was used to silanize the surface of silicon wafer,cellulose. HDMS may be used to dehydrate cells of biomaterials for scanning electron microscopy (SEM). HDMS mediated ring opening polymerization of Α-helical polypeptides. Zinc blende nanocrystals were prepared in the presence of HDMS.

General description

Hexamethyldisilazane (HDMS) is a bulk organo silicon compound. It is hydrophobic in nature.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 flocculations, during synthesis.
