A polymeric composite may be used for forming fluid separation membranes. The fluid separation membranes may go through a separation selectivity maximum as a function of operating conditions (e.g., temperature and/or pressure). The membranes may be formed from polyamide or poly (pyrrolone-imide). Polyamides may be formed by the condensation of a tetraamine, a tetraacid, and a diamine. Poly (pyrrolone-imides) may be formed by the condensation of a polyamide.
L'invention concerne un matériau composite polymère servant à former des membranes de séparation de fluides. Lesdites membranes peuvent passer par un maximum de sélectivité de séparation en tant qu'aspect de fonctionnement de conditions (par exemple, température et/ou pression). On peut constituer les membranes à partir du polyamide ou du poly (pyrrolone-imide). On peut constituer les polyamides par condensation d'un tétramine, d'un tétracide et d'une diamine. On peut former des poly (pyrrolone-imides) par condensation d'un polyamide.
