General description

Tetraethylene glycol dimethyl ether or tetraglyme is an organic aprotic colourless solvent with film forming ability.

Application

Tetraglyme coating was applied on glucose sensors, such as Nafion by RF to render it “non fouling” and enhancing linking of bio mimetic molecules to the surface. Tetraglyme helps in selective adsorption of proteins while promoting cell adhesion. Other general uses include as an electrolyte in lithium ion battery.

A novel sulfur/graphene nanosheet (S/GNS) composite was prepared via a simple ball milling of sulfur with commercial multi-layer graphene nanosheet, followed by a heat treatment. High-resolution transmission and scanning electronic microscopy observations showed the formation of irregularly interlaced nanosheet-like structure...
