Abstract

A method of making large ultrathin free-standing polymer films without use of a sacrificial layer includes the steps of providing a substrate, applying a polyelectrolyte material to said substrate, applying a polymer material onto said substrate and onto said polyelectrolyte material, and directly delaminating said polymer material from said substrate and said polyelectrolyte to produce the ultrathin free-standing polymer film.
