The incorporation of a fluorinated ether functionality into a polymer or surfactant to enhance C02-solubility

Steric Stabilization of Colloids by Poly(dimethylsiloxane) in Carbon Dioxide: Effect of Cosolvents

“…The incorporation of "CO 2 -philic" segments into block and graft copolymers has led to surfactants that can sterically stabilize colloids in liquid or supercritical CO 2 . CO 2 -philic polymers include poly(fluoroacrylates), poly(fluoroethers), siloxanes, and oligomers of propylene and butylene oxides (1,(3)(4)(5).…”

Catalytic Activation of Carbon-Fluorine Bonds by a Soluble Transition Metal Complex

“…We have recently shown that C-Si and C-H bond formation can proceed at competitive rates (13). In this case, only C-H formation takes place, undoubtedly because of the trans C6F5 and SiR, arrangement.…”

The effects of supercritical CO2 formulations on the removal of high-dose ion-implanted photoresists

“…4, the stripping efficiency was found to be dependent on the temperature at the constant pressure (10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20)(21)(22)(23)(24)(25). The stripping rate increased with the elevated temperature below 60°C, while the reverse results were obtained at 70°C and 80°C.…”

“…Fluorine and silicon-based surfactants were first used to form scCO 2 stable microemulsions due to the high solubility in scCO 2 [20,21]. While hydrocarbon-based surfactants are difficult to dissolve in scCO 2 , co-solvents and specific additives are usually added to increase the solubility of hydrocarbon surfactants in scCO 2 [22][23][24].…”
