Polydimethylsiloxane-diamond porous composite material for preconcentration of organic compounds

What is it about?

Polydimethylsiloxane based sorptive devices are light (floating at the surface of aqueous samples) and have a limited surface area. This results in incomplete contact with aqueous samples and slow adsorption kinetics due to dominant partiton mechanism in absorption of organic compounds of interest. A more developed porous structure of new material provides a better mass transfer, while embedded higher density microdiamond particles increase total density of material and it can sink in aqueous solutions to provide full contact with sample.

Why is it important?

New material provides a better performance in terms of kinetics and recovery. Moreover it has a better thermostability, which is important for thermodesorption related analysis.
