Process for manufacture of proton conductive polymer gel useful as backfill for sacrificial and impressed current anode systems

摘要

The process of the present invention provides for the manufacture of a novel proton conductive polymer gel useful as backfill for sacrificial and impressed current anode systems. The process of the present invention is carried out in aqueous phase thus providing a cheaper option besides the use of ingredients readily available in the international markets. The polymer used as backfill is transformed into a proton conducting form in the gelated network through an in-situ doping process during gelation. The gel product produced can be sliced to sheet of any desired size suitable and compatible to concrete or soil medium. The novelty of the product of the present invention is that it can be used as backfill between any anode such as sacrificial or impressed current mode and is adaptable to the concrete surface both in the presence of moisture or absence of moisture, which is not hitherto been achieved in prior art. Further, the specialty of the utility of this product, is its compatibility with all the sacrificial anodes such Mg, Al, Zn which is not hitherto been realized with any of the earlier chemical backfill known for this application.
