Membrane Materials for Gas and Separation (eBook, PDF)

Synthesis and Application fo Silicon-Containing Polymers

• Format: PDF

Produktbeschreibung

Si containing polymers have been instrumental in the development of membrane gas separation practices since the early 1970s. Their function is to provide a selective barrier for different molecular species, where selection takes place either on the basis of size or on the basis of physical interactions or both. * Combines membrane science, organosilicon chemistry, polymer science, materials science, and physical chemistry * Only book to consider polymerization chemistry and synthesis of Si-containing polymers (both glassy and rubbery), and their role as membrane materials * Membrane operations present environmental benefits such as reduced waste, and recovered/recycled valuable raw materials that are currently lost to fuel or to flares
