A Study on Anticorrosion and Antibiofouling Properties of Poly (NBA –co-AM/AMPSNa) Hydrogel

Abstract

            The Hydrogel poly (N-Tertiary butyl acrylamide-co-acrylamide/2-Acrylamido-2-methyl-1-propane Sodium sulfonate) (NBA-co-AM/AMPSNa) –HG47 was used as corrosion inhibitor on carbon steel in acidic medium. and as antibiofouling agent. The anticorrosion property of the hydrogel was determined by weight loss method, in 0.5M   HCl medium. The protective film that formed on the surface of the metal which resists the corrosion was confirmed by  FT-IR. The inhibitor’s type of protection is determined by electrochemical studies. The film formation is also confirmed by the surface morphology SEM and EDAX and hardness analysis. This shows the complex formation between the metal cation and the hetero atoms that are present in the Hydrogel. The antibiofouling against the   germination of zoospores of Ulva Lactuca   showed a promising result.
