Polymer materials functionalized with basic salts

Abstract

A modified acid neutralizing polymer material includes a substrate having a surface including an acid neutralizing polymer material and a modified layer formed on the acid neutralizing polymer material surface. The modified layer includes a reaction product between a basic salt solution and the acid neutralizing polymer material surface. A method for preparing the modified acid neutralizing polymer material includes receiving a substrate comprising an acid neutralizing polymer material, applying a basic salt solution to the substrate to create a modified substrate through a reaction product between the basic salt solution and the acid neutralizing polymer material to form the modified acid neutralizing polymer material, allowing the basic salt solution to evaporate from the modified substrate, and optionally, removing unreacted basic salt material from the modified acid neutralizing polymer material.
