Methods for forming polymer surface polymer layers using radical atom transfer polymerization (ATRP) are described. The method may include functionalization steps prior to surface initiated ATRP, such as hydroxylation and / or halogenation steps. The hydroxylation step can be performed in a solution that includes potassium persulfate, ammonium persulfate or lithium hydroxide. The halogenation step can also be performed in a solution. The methods described herein can be performed on hollow polymer fiber groups, including polymer fiber groups mounted on a module. |
