Methods for modifying a hydrophobic polymer surface and devices thereof
First Claim
1. A method of modifying a surface of a non-porous hydrophobic polymer substrate, the method comprising:
- contacting the surface of the non-porous hydrophobic polymer substrate with a liquid composition comprising a nucleophilic reagent and a catalyst, wherein the non-porous hydrophobic polymer substrate comprises a polymer having a backbone containing electrophilic linkages; and
maintaining the composition in contact with the surface of the hydrophobic polymer substrate in a manner sufficient to convert at least a portion of the surface from hydrophobic to hydrophilic by transesterification while retaining the mechanical and optical properties of the polymer substrate.

Abstract
Aspects of the invention include methods for modifying a surface of a non-porous hydrophobic polymer substrate having a backbone containing electrophilic linkages. In practicing methods according to certain embodiments, a liquid composition having a nucleophilic reagent and a catalyst is contacted with the surface of the non-porous hydrophobic polymer substrate and maintained in contact with the surface of the polymer substrate in a manner sufficient to convert at least a portion of the surface from hydrophobic to hydrophilic while retaining the mechanical and optical properties of the polymer substrate. Substrates, including containers, having one or more hydrophilic surfaces and kits suitable for practicing the subject methods are also described.
