SARFUS: Study of dibloc copolymer microphase structuration
In the experiment discussed here the thin layer of diblock copolymer is formed by spin-coating from solution. The initial diblock copolymer is quite disorganized, meaning that the material is not microphase separated and so the PS and PMMA segments are intimately mixed. When the dibloc copolymer is heated, the diblock will slowly organize. Sarfus was used to investigate the surface structure of the diblock copolymer. 

Sarfus: Characterization of adhesive nanometric layer on SiO2 surface
In this work, two well-known protective adhesives designed for microelectronic applications have been studied with the Sarfus technique. Theses adhesives are described as providing clean removal during masking operations but the presence of nanometric organic layers is shown.

Study of PDMS and 8CB prewetting films by Sarfus
The prewetting films of a methyl-terminated PDMS droplet and 8 CB liquid crystal are characterized by SARFUS. Thin layers of 0.7 and 3.3 nm are measured on both systems, respectively.

Characterization of a thermo-responsive polymer film in air and in water

A dynamic study of a thermo-responsive nanometer-thin polymer film is performed with the Sarfus 3D-IMM equipment. The ability to carry out an analysis in air as well as in liquid and to easily characterize a thermal transition with a live visualization of the layer quality and morphology is demonstrated.
