Synthesis of fluorinated polymers in supercritical carbon dioxide (scCO₂)
… were carried out in homogeneous phase with supercritical CO₂. Polymerizations were carried out at 140°C, 1500 bar and were initiated with di-tert-butyl peroxide (DTBP). In-line FT-NIR (Fourier Transform- Near Infrared) spectroscopy showed that complete monomer conversion may be obtained. …

Supercritical carbon dioxide-processed resorbable polymer nanocomposites for bone graft substitute applications
… In the presented work, we describe the use of supercritical carbon dioxide (scCO<sub>2</sub>) processing to create porous resorbable polymeric constructs reinforced by nanostructured, organically modified Montmorillonite clay (nanoclay). scCO<sub>2</sub> processing simultaneously disperses the …

The Manufacture of Polymer Nanocomposite Materials Using Supercritical Carbon Dioxide
The use of supercritical carbon dioxide (scCO₂) as a processing aid to help exfoliate nano-clays and improve their dispersion during melt blending in polymer matrices has been reported in the literature. One of the best processes in terms of improving the degree of nano-clay dispersion and …
