首次在没有任何球形材料作为模板的情况下，通过聚乙烯吡咯烷酮（PVP）稳定的磁性自组装过程合成了碗状镍纳米粒子。微量的掺杂碗可以诱导液晶（LC）分子进入完美的平面排列，这归因于它们的碗状形状和磁性自组装成一维结构。这将提供一种通过掺杂特殊纳米结构材料来建立液晶取向的新方法。
Nickel bowl-like nanoparticles have first been synthesized by a magnetic self-assembly process stabilized by polyvinyl pyrrolidone (PVP) without any sphere-like materials as templates. A trace of doped bowls can induce liquid crystal (LC) molecules into a perfect planar alignment, attributable to their bowl-like shape and magnetic self-assembly into a 1D structure. It would provide a novel method of establishing LCs alignment by doping special nanostructured materials.
