Polymère sensible au pH

Un polymère sensible au pH est un polymère ionique qui répond aux changements du pH du milieu environnant par la variation de ses dimensions. Ces polymères peuvent gonfler ou se contracter en fonction du pH de leur environnement. Ce comportement a lieu grâce à la présence de certains groupes fonctionnels dans la chaîne du polymère. Un polymère sensible au pH peut être anionique ou cationique répondant à des valeurs basiques ou acides de pH. Ces polymères peuvent être conçus av...
