首次合成的疏水杂化聚合物Bu4N+-POM-PS通过质子化反应形成了一个由亲水性H+-POM头部和疏水PS尾部组成的巨型两亲性聚合物。立刻，杂化的两亲分子就会自我组装成囊泡。进一步的热处理诱导从囊泡演化为含有包裹有PS冠状H+-POM纳米管的管状聚集体。经过这一转变，管状聚集体进一步长大，然后以平行的方式排列形成结构域。这一有趣的形态演化为我们提供了一个了解杂化两亲分子有趣的聚集行为的机会，同时也提供了生成POM纳米管的机会，该纳米管可能被用来创建潜在应用的纳米材料。
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.
