Patterned hydrophilization of nanoporous 1,2-PB by thiol-ene photochemistry.

We present an efficient method for functionalizing the large polymer-air interface of a gyroid nanoporous polymer. The hydrophilicity of nanoporous cross-linked 1,2-polybutadiene is tuned by thiol-ene photo-grafting of mercaptosuccinic acid or sodium 2-mercaptoethanesulfonate. The reaction is monitored by FT-IR, UV-Vis, contact angle, and gravimetry.
