The dewetting of thin films of low molecular weight diblock and triblock copolymers of poly(oxyethylene)/poly(oxybutylene) on silicon has been studied using video microscopy and X-ray reflectivity. Dewetted films were observed to comprise polygonal domains of polymer droplets, with a domain size of
## Abstract A polystyreneβ__block__βpoly(ethylene oxide) block copolymer bearing a photocleavable junction between the blocks is used to form nanoporous thin films with carboxylic acid functions homogeneously distributed on the pore walls. The presence of the carboxylic acid groups is evidenced by
