ABSTRACT:
Proteins are applied to a polymeric article by contacting the polymeric article with a protein and exposing the contacted polymeric article to a frequency with a sufficient power dissipation for a sufficient period of time. A frequency range for applying proteins to a polymeric article is between about 5 kHz to about 40 kHz with a minimum power dissipated of about 1 watt. As a result, polymeric articles so treated exhibit improved water wettability, proteins may be applied to the polymeric articles very rapidly and more uniformly than by other methods, and polymeric articles having selected zones of wettability may be produced.
