A polymer having a surface with increased hydrophilicity comprises a functionalized surface with a modified water contact angle less than the contact angle characteristic of an as-received, non-functionalized polymer surface. A method for making the hydrophilic polymer having the functionalized surface comprises exposing the non-functionalized surface to a plasma and a reactive gas.
