Poly(ethylene oxide) side chains are the key structures in a novel azobenzene polymer with improved properties: firstly, they increase film fluidity, thus supporting surface relief gratings (SRGs) with Ar ion lasers, and secondly, their cross-linking with formaldehyde fixates this otherwise thermally reversible surface modification. The Figure shows an SRG-modified film of the new polymer.
