The originally synthesized hydrophobic hybrid polymer Bu4N+-POM-PS is tuned into a giant amphiphile composed of a hydrophilic H+-POM  head and a hydrophobic PS tail through protonation. Immediately, the  hybrid amphiphiles self-assemble into vesicles. A further annealing  treatment induces an evolution from vesicles to tubular aggregates  containing H+-POM nanotubes wrapped with PS coronas. After  this transformation, the tubular aggregates grow further and then  arrange in a parallel manner to form domains. This interesting  morphology evolution provides us an opportunity to understand the  intriguing aggregation behavior of the hybrid amphiphiles and,  meanwhile, to generate POM nanotubes which might be utilized to create  nanomaterials for potential applications.
