Containers with active surface and methods of forming such containers

Abstract

Provided are containers comprising: an enclosure member; and optionally an article at least partially within the enclosure member. The enclosure member and/or the article comprise an activated polymeric surface, wherein the enclosure member and/or the article comprise an activated polymeric surface, wherein the activated polymeric surface is formed by a method comprising treatment of a sulfonated polymeric surface with a composition comprising a protic acid. Also provided are methods of forming containers. The containers and their methods of formation find particular use in the storage of high purity chemicals useful in the electronics industry, and in the water, pharmaceutical and food and beverage industries.

1 . A container, comprising:
 an enclosure member; and   optionally an article at least partially within the enclosure member;   wherein the enclosure member and/or the article comprise an activated polymeric surface, wherein the activated polymeric surface is formed by a method comprising treatment of a sulfonated polymeric surface with a composition comprising a protic acid.   
     
     
         2 . The container of  claim 1 , wherein the enclosure member comprises an activated polymeric surface. 
     
     
         3 . The container of  claim 1 , wherein the article comprises an activated polymeric surface. 
     
     
         4 . The container of  claim 3 , wherein the article is an enclosure member liner. 
     
     
         5 . The container of  claim 3 , wherein the article is a container insert that is not an enclosure member liner. 
     
     
         6 . The container of  claim 1 , wherein the container contains an ultrapure chemical composition in contact with the activated surface. 
     
     
         7 . The active container of  claim 1 , wherein the container contains water, a pharmaceutical, a food, a beverage, or an electronic material, in contact with the activated surface. 
     
     
         8 . A method of forming a container having an activated polymeric surface, comprising providing an enclosure member or an enclosure member liner comprising a sulfonated polymeric surface, and treating the sulfonated polymeric surface with a composition comprising a protic acid. 
     
     
         9 . The method of  claim 8 , wherein the protic acid is chosen from one or more of nitric acid, hydrochloric acid, sulfuric acid, or acetic acid. 
     
     
         10 . The method of  claim 8 , wherein the composition comprising the protic acid further comprises an oxidizing agent that is different from the protic acid. 
     
     
         11 . The method of  claim 8 , further comprising after treating the sulfonated polymeric surface with a composition comprising a protic acid, treating the polymeric surface with a base.
