Abstract
A nanoporous film formed from a series of vinyl addition block polymers derived from functionalized norbornene monomers are disclosed and claimed. The nanoporous films as disclosed herein are useful as pervaporation membranes and antireflective coatings among various other uses. Also disclosed herein are the fabrication of nanoporous films into pervaporation membranes which exhibit unique separation properties, and their use in the separation of organic volatiles from biomass and/or organic waste, including butanol, phenol, and the like. The fabrication of nanoporous films into antireflective coatings are also disclosed.
