Poly Acrylic Acid Ethyl Acrylate as Smart Carrier for Rebar Inhibitor Delivery in Alkaline Condition

摘要

With ethyl acrylate, acrylic acid as monomers, an intelligent carrier material (PAE) was synthesized, and its swelling properties at different pH values, its cycle characteristics as well as its release control performance for inhibitors in alkaline solution were studied. The results indicate that the synthesized material is sensitive to pH and has excellent cycle performance which is suitable for controlling drug delivery in the pH range from 10 to 11.
