Methods of forming a polymer layer on a polymer surface

摘要

Methods of forming polymer layers on polymer surfaces using surface initiated atom-transfer radical-polymerization (ATRP) are described. The method can include functionalization steps prior to performing surface initiated ATRP, such as hydroxylation steps and/or halogenation steps. The hydroxylation step can be carried out in a solution including potassium persulfate, ammonium persulfate, or lithium hydroxide. The halogenation step can also be carried out in a solution. The methods described herein can be performed on bundles of hollow polymer fibers, including bundles of hollow polymer fibers mounted in a module.

1. A method of forming a polymer film on a polymer surface, the method comprising the steps of:
halogenating a polymer surface having hydroxyl groups bonded thereto in a halogenation solution, the halogenation solution comprising hydrobromic acid, hydrochloric acid, phosphorous tribromide, phosphorous trichloride, hydroiodic acid, thionyl chloride, thionyl bromide, or combinations thereof; and performing surface initiated atom-transfer radical-polymerization on the polymer surface, wherein the surface initiated atom-transfer radical polymerization forms a polymer film on the polymer surface.
