| titleOfInvention | Functional micro-extraction probe with polysiloxane-modified graphene polymeric coating and preparation method thereof |
| abstract | The invention belongs to the field of analytical chemistry, and particularly relates to a functional microextraction probe with a polysiloxane-modified graphene polymeric coating and a preparation method thereof. The microextraction probe is a microextraction probe with a polymerized structure of stainless steel fiber-S-C-polysiloxane-S-C-bridging agent-S-C-graphene oxide, which is formed by sequentially assembling and bonding a polysiloxane functional monomer with a three-dimensional cage-shaped structure, a sulfhydryl bridging agent and modified graphene oxide containing ethylenic bond functional groups layer by layer through sulfydryl-alkenyl click chemistry and carrying out sulfydryl bond combination with sulfydryl modified on the surface of a stainless steel wire. The prepared polymeric coating has larger specific surface, delocalized pi-pi bond and hydrophobic effect, has good adsorption performance on volatile aromatic organic pollutants in environmental water, and can provide good pretreatment materials and technical support for environmental analysis. |
