Deposition of polymers on solid surfaces allows the complete modification of the physico-chemical characteristic of a surface. Depending on the nature of the polymer deposited, it is possible to control such surface properties as hydrophilicity, hydrophobicity, adhesion and lubrication, biocompatibility and others [1]. In some applications it is also desirable to pattern polymer layers. Tuning the morphology of a surface and chemical structure is an effective way for creation of membranes, catalysts supports, cell culture media, antireflection coatings.

Here, we describe the simple patterning method, which is based on spontaneous dewetting of thin poly(glycidylmethacrylate) (PGMA) film. This polymer is well known as an universal coupling agent [2]. It was found that PGMA spincoated from different solutions may form homogeneous PGMA layer or undergoes dewetting and forms porous, chainlike or patched layers of PGMA. Type and size of the structures depends on concentration of PGMA and thermodynamic properties of the solvent and can be predicted. Obtained structures were amplified to the patterned polymer layers by grafting of the carboxy-terminated homopolymers.
