Thermostability of polymeric langmuir–blodgett films

Abstract

Communication: LB films stable against desorption up to 250°C have been produced from prepolymerized polyurethanes, polyimides and polyamic acid and studied using optical reflection, microscopy, ellipsometry, ESCA, FT‐IR and small angle X‐ray scattering (SAXS). Due to their stability, the materials could be used to prepare multilayer films or as matrices for dyes opening up applications in optics.
