聚合物晶体体是一类中空结晶聚合物纳米粒子，其壳由具有破缺平移对称性的单晶形成。它们显示出与球形填料相关的有趣的机械、热和生物医学特性。先前报道的晶体是由准二维片层形成的，可以很容易地平铺在球形表面上。在这项工作中，报道了由一维聚合物晶体形成的聚合物晶体的形成。由于其一维生长习性，选择聚（3-己基噻吩）（P3HT）作为模型聚合物。 P3HT 晶体体是使用细乳液溶液结晶方法成功制备的，经扫描电子显微镜和透射电子显微镜证实。 X射线衍射（XRD）和选区电子衍射实验证实P3HT结晶成I型晶体结构。 XRD、差示扫描量热法和紫外-可见光结果揭示了曲率相关的结构、热和电光特性。
Polymer crystalsomes are a class of hollow crystalline polymer nanoparticles with shells formed by single crystals with broken translational symmetry. They have shown intriguing mechanical, thermal, and biomedical properties associated with spherical packing. Previously reported crystalsomes are formed by quasi‐2D lamellae which can readily tile on a spherical surface. In this work, the formation of polymer crystalsomes formed by 1D polymer crystals is reported. Poly (3‐hexylthiophene) (P3HT) is chosen as the model polymer because of its 1D growth habit. P3HT crystalsomes are successfully fabricated using a miniemulsion solution crystallization method, as confirmed by scanning electron microscopy and transmission electron microscopy. X‐ray diffraction (XRD) and selected area electron diffraction experiments confirm that P3HT crystallized into a Form I crystal structure. XRD, differential scanning calorimetry and UV–Vis results reveal curvature‐dependent structural, thermal and electro‐optical properties.
