Surfactants spontaneously form worm‐like structures inaqueous solutions by changing the ambient conditions and/or bybeing adsorbed on different substrates. Vesicle formation has beenobserved by adding anionic charged surfactants to a cationic chargedsurfactant solution. In analogy to these systems, shape transitionsof so‐called crew‐cut amphiphiles in organic solventsand after an additional change of solvent have been investigated. Theadsorption behaviour ofpoly(butadiene–block‐2‐vinylpyridene)on chemically different substrates has been investigated by scanningfocus microscopy on different dried surfaces. This study shows thatnot only the ambient conditions acting in the solution but also thesubstrates used have a significant influence on the shapes formed.Furthermore, the morphologies in dependency of the chain length havebeen investigated.
