<scp>pH</scp> ?sensitive polymers: Classification and some fine potential applications

Stimuli-responsive materials in general and pH-responsive polymers particular have gained increasing interest during the last two decades. Their unique properties, which arise from their ability to exhibit sharp reversible changes response environmental pH conditions, made them suitable for various applications such as drug delivery specific body-site targeting, sensing actuation, membrane functionalization, separation techniques, well agriculture food industry even chemical industries. In present review, focus is on characteristics of terms origin, composition, preparation. Moreover, some important recent are reported discussed.
